## Abstract

Based on system theory and human-land relationship theory, the evolution characteristics of the habitat environment of scenic fringe rural tourism sites are summarized in three aspects, including self-organisation, periodicity, and volatility. Taking the tourism circle of Xiananshan Village in Liandu District in Lishui as an example, the spatial and temporal changes in the flow of tourism factors are taken as the main driving factors, and a dynamic model of the evolution of the habitat environment of scenic fringe rural tourism sites is constructed. The regulation process is to clarify the inner connection between the spatial and temporal patterns of rural habitat environment and the tourism development process and to seek the habitat environment of rural tourism sites on the edge of scenic areas.

## Body

## 1. Introduction

Scenic-edge rural tourism sites are rural tourism destinations developed on the edge of famous scenic areas and with scenic areas as their core, relying on rural-specific tourism resources and stable sources of tourists from scenic areas [1, 2]. This special type of tourism place has both the general characteristics of rural tourism places and its own uniqueness, often combining many features such as geographical spatial dependence, complementary tourism resources, shared source markets, and relatively lagging regional economy and complexity of interest subjects, becoming a key support area for coordinating integrated regional development and an important geographical support for tourism transformation and expansion of quality in core scenic areas. It is also one of the important areas of concern for human geography and tourism geography in China. With the transformation of the tourism life cycle in core scenic areas, rural tourism sites on the periphery of scenic areas have gained rapid development opportunities, but they have also triggered a series of human-land relationship crises, prompting widespread concern for the habitat of this type of area [3]. Therefore, how to deal with the potential threat of tourism development to the habitat of scenic rural tourism areas, explore the spatial and temporal characteristics and mechanisms of the evolution of the habitat of scenic rural tourism areas, and seek appropriate models for the construction of the habitat of scenic rural tourism areas has become one of the important issues facing various disciplines, including tourism science [4].Since 2006, the comprehensive development of China’s new rural construction and the upgrading and adjustment of the rural industrial structure have provided good conditions for carrying out rural habitat construction and research, and the research horizon has shifted from the evaluation and improvement of rural habitat at different spatial scales [5, 6] to the integration of multidisciplinary research, in which the planning and design [7], evolutionary laws [8], construction methods of rural habitat [9], and other issues have attracted the continuous attention of scholars. Overseas rural habitats have mainly focused on the theoretical system of rural settlements [10], the evolution and mechanism of rural habitats [10, 11], and the sustainable development of rural habitats [12]. However, there is still room for further research on the habitat environment of this unique geographical unit, which is the edge of the scenic area. The spatial and temporal evolution characteristics and mechanisms of the habitat environment of this type of area are obviously unique, involving many disciplines such as tourism geography, ecology, economics, and sociology, and need to be explored and expanded innovatively under a new research idea and theoretical framework [13].It is noteworthy that some Chinese tourism scholars have become aware of the interaction between tourism and habitat and have conducted exploratory studies. Some scholars have analysed the intrinsic relationship between tourism development and the quality of urban habitat [14] and through quantitative analysis have found a significant positive correlation between the level of habitat development and the attractiveness of urban tourism [15]. Some scholars have also studied that rural habitat from the perspective of urban-rural integration has attracted the attention of scholars [16]. Although Chinese tourism scholars have begun to engage in research on the habitat environment, the research results are still rather scattered and thin, and the habitat environment of rural tourism sites on the edge of scenic areas has not received sufficient attention, and the relevant basic theoretical research is particularly insufficient. Related to this is the multiperspective study of rural tourism sites; for example, in the social and cultural aspects of rural tourism sites, the residents’ perceptions [17], dynamics, processes, types, and inheritance patterns of cultural changes in rural tourism sites have been analysed [18–20]. In terms of the spatial structure of rural tourism sites, the spatial structure characteristics, evolutionary patterns, and optimization paths of rural tourism sites around cities are analysed from different spatial scales [21–23]. All these show that rural tourism land as an independent geographical unit has greater research value and application space and also provide a good academic reference for the design of this paper.


## 2. Related Work

### 2.1. Current Status of Research in the Urban Fringe

In 1936, the German geographer Herbert Louis first proposed the urban fringe zone when he studied the geographic structure of Berlin from an urban morphological perspective [24], and in the 1960s, the British MRG Conzen, who focused on the urban landscape, proposed the urban fringe zone not only as a way of explaining changes in the urban landscape [25] but also as a means of ordering the complex process of urban development. He argues that the urban fringe is the frontier of urban territorial diffusion but that this expansion is not a steady progression but rather a cyclical change in three states, acceleration, stasis, and deceleration, and graphically compares this cyclical structure of urban development to the annual rings of trees. In his study of the structure of the edge zone of the town of Alnwick in Northumberland, he identified three components: the inner edge zone, the middle edge zone, and the outer edge zone. In China, the study of the urban fringe began in the 1980s and developed rapidly in the 1990s, when the theoretical framework for the study of the urban fringe in China took shape [26]. Many scholars have discussed and researched the concept, geographical definition, and characteristics of urban fringe areas. In addition, [27] planning and land use methods of urban fringe areas have been studied in some detail. In recent years, the emergence of urban villages has become a new direction of research related to urban fringe areas. [3] analyses the formation mechanism of urban villages from the perspective of land use, argues that the prerequisite for urban village transformation is land conversion, and proposes a specific policy framework for land and housing conversion in urban villages, putting forward the idea of “bottom-up” village-oriented urban village transformation.


### 2.2. The Current State of Research in Rural Settlement Landscapes

In China, ecological research on rural landscapes has mainly focused on the construction of “equivalence.” The rising movement of “ecovillages” has positive theoretical and practical implications for the ecological construction of rural landscapes in China, and the construction model of “ecovillages” provides new ideas for the design of rural landscapes [12].The Danish scholar Giman was the first to propose the concept of “equivalence,” which is defined as “a human-scaled settlement.” Within the settlement, human activities do not damage and be integrated into the natural environment, support healthy human development, and are sustainable into an unknown future. In Japan, [13] has designed three models of ecovillages, depending on the urban influence on rural areas: (1) the ecovillage model for large urban fringe areas; (2) the ecovillage model for typical agricultural areas; and (3) the ecovillage model for remote mountainous areas.The pattern of landscape evolution is different for villages near large cities, urbanised villages, and remote isolated villages. [14] also found that the trend towards industrial agriculture led to a concentration of population and the expansion of new villages, but at the same time, thousands of small villages were abandoned and gradually disappeared, resulting in a fundamental change in the structure of rural settlements. [15] systematically explores the evolution of rural settlements from prehistory to the present, selects three types of villages, agricultural, mining, and pastoral, and illustrates their evolution in terms of different time periods, natural environments, village sizes, cultural contexts, and differences in people’s perceptions of the landscape.In Europe, [16] suggests that the sustainable development of the countryside and healthy village life requires the revitalisation of the entire rural area in terms of its nature, human, and built environment, with a focus on the preservation of rural settlements. The cultural landscape of rural settlements is actually a socioecological adaptation of people to the natural ecological environment of the countryside, and each landscape is an active adaptation to the natural geographical environment [28]. The study finds that the cultural landscape of rural settlements in China is a kind of kinship culture, with specific cultural forms and forms, forming a pluralistic regional culture, which works together with other human cultures. [29] introduces the rural settlement landscape as a dynamic interweaving of natural and human landscapes, reflecting the common values of the group formed by nature, social, humanistic, technological, historical, mythological, and psychological consciousness in the region.

## 3. Definition of Urban Fringe Areas

Over the years, scholars in China and abroad have held different views on the definition of urban fringe, and the use of the concept is rather confusing. Similar to the term “urban fringe,” there are other terms such as city country fringe, urban fringe, area of urban sprawl, and urban shadow area.One of the first people to address the concept of a transition zone between urban and rural areas was the German geographer Herbert Louis. In his year in Berlin, he identified certain areas that were formerly part of the city boundaries but were later encroached upon by the built-up area and became part of the urban area, which he called the urban fringe, and pointed out that this zone had many significant differences from the built-up area, with its unique spatial structure, housing types, services, and so on. This concept was subsequently deepened and refined by many planners, architects, geographers, and other scholars from all walks of life. A more precise definition of the urban fringe was provided by [10], who described it as “a zone of change in land-use, social and demographic characteristics, located in a land use transition zone between a contiguous built-up area and a suburban area, and a purely agricultural hinterland with an almost complete absence of non-agricultural housing, non-agricultural land-use and non-agricultural land-use.” At present, most Chinese scholars consider the urban fringe as a kind of discontinuous territorial entity formed at a specific stage of urban development, close to urban areas, and a zone continent in which the social and economic elements between urban and rural areas are intensely transformed. This paper argues that the urban fringe is a transitional zone where the urban and rural hinterlands meet and is a product of the combination of urban and rural areas, with obvious mixed urban-rural characteristics, and its landscape features also combine the landscape characteristics of urban and rural areas.The urban and rural areas are two very different heterogeneous bodies, and the urban fringe is the part where these two heterogeneous bodies are combined. However, where this combined part starts and how to define the scope of the urban fringe has been the focus of academic discussion.According to Friedman’s qualitative approach, which is based directly on the daily commuting range of people’s experience, the area around the city is classified as the urban fringe, where the inner fringe is about 10-15 km and the outer fringe extends up to 2550 km [11]. Some Chinese scholars have used the length of people’s commuting time to measure the urban fringe from a psychological perspective. They argue from the actual situation in China that urban transport in China is still dominated by public transport, and therefore, the extent of the urban fringe in China should take into account the spatial and temporal distance of a one-hour commute by public transport (including buses as well as BRT and rail transport) [14].


### 3.1. The Human-Place Relationship in Tourism

Based on the theories related to human-territory relations proposed by [15] and the characteristics of tourism geography, the theoretical content of tourism human-territory relations can be summarized from a philosophical perspective as shown in Figure 1.Figure 1
Theoretical framework of tourism-man-land relationship.This system is engaged in tourism activities of human and geographic environment elements in a certain territorial space range, in accordance with certain laws intertwined, constituting a certain structure and function of the complex open system [21], with distinctive tourism, regional, open, dynamic, and comprehensive characteristics. The “people” are in the active position in the tourism-human-land relationship and can passively recognize, use, change, and protect the geographical environment; the study of “people” is about improving tourism satisfaction. “Geographical environment” refers to the geographical environment related to tourism activities, including the natural environment, human environment, and its composite environment of tourism places; geographical environment is the material basis and spatial place of human tourism activities, geographical environment affects the geographical characteristics of human tourism activities and restricts the depth, breadth, and speed of tourism activities; in research, the “land” is the effective protection and sustainable use of tourism resources and environment. Tourism “human-territory relationship” refers to the formation of a specific tourism region in the relevant constraints and interdependence of objective relations, including human tourism activities on the geographical environment of the relationship of dependence, the geographical environment on human tourism activities constraints, and the geographical environment of the interaction of cause-and-effect relationships, and human tourism activities affect the geographical environment.Although most scholars believe that the tourism experience is the essence of tourism [28], there is no consensus on the nature of tourism geography phenomenon and the nature and research core of tourism geography. Based on the theoretical perception of tourism human-terrestrial relations, tourism geography is a science that object is the “tourism territorial system.” The theory of human-territory relations is an important basis for the construction of the theoretical framework of tourism geography. The human-territorial relationship in tourism is not static; the material cycle and energy transformation between the two subsystems of human tourism activities and the geographical environment lead to dynamic changes and developmental evolution of the human-territorial system of tourism [22].Scientific methodology is an important tool for exploring scientific issues in tourism geography. Empiricist, positivist, humanistic, and structuralist methodologies are undoubtedly common and effective research methods in tourism geography. The analysis of the territorial system of human-territory relations in tourism is not enough to rely on qualitative research alone but needs to be combined with quantitative analysis [21]. The two major methodologies are derived from the characteristics of the discipline of geography, namely, the comprehensive and systematic analysis method and the regional and area analysis method [24].


### 3.2. The Basic Framework of Tourism Geography Theory

Based on the theoretical perspective of the relationship between people and place, the theoretical framework of tourism geography is constructed based on the tourism activity system and the geographical environment system, with the theory of the relationship between people and place as the core and the theories of related disciplines integrated, in accordance with the development requirements of the systematization and scientificization of tourism geography theory, taking into full consideration the disciplinary attributes of tourism, regional, comprehensive, and application of tourism geography. The theory of tourism geography includes both the theory of tourism geography science from the perspective of “people” and the theory of tourism geography science from the perspective of “place,” while the theory of tourism human-territory relationship from the perspective of “people-territory synthesis” is always the most important one. Through interdisciplinary exchanges and theoretical borrowing and integration, the theoretical essence of tourism geography from related disciplines (such as tourism, geography, philosophy, history, sociology, economics, ecology, environment, management, and ethics) can be absorbed to enrich the theoretical content of tourism geography and build a complete theoretical system of tourism geography as shown in Figure2.Figure 2
Theoretical framework system of tourism geography.“People” are the dominant factor in the interaction between tourism and human-territory relations. All people involved in tourism activities are the object of studying in tourism geography. Theories related to the study of “people,” such as tourism demand theory, tourism psychology, tourism anthropology theory, tourism marketing theory, stakeholder theory, experience tourism theory, tourism sociology theory, and tourism aesthetics theory, can be used as the theoretical basis of tourism geography.“Land” is the special place where human beings carry out tourism activities and the basic factor of tourism human-land relationship. Any geographical environment related to tourism activities, including the natural environment, human environment, social environment, and even artificial environment, can become the object of tourism geography research. Theories related to the study of “place,” such as theories of physical geography, human geography, landscape ecology, and environmental science, can also be used as the theoretical basis of tourism geography.The theory of tourism geography is from the perspective of “human-land integration.” Tourism geographic phenomena and patterns are the product of the interaction between the natural environmental complex and the tourism activity complex. Between human tourism activities and the geographical environment, there are complex relationships of human visitation behaviour, tourism development and utilization, industry operation and economy, community participation, government policy regulation and control, and tourism spatial organisation. Theories related to the study of these relationships, such as regional economic theory, urban planning and tourism planning theory, tourism industry geography theory, tourism transportation geography theory, tourism community participation theory, and tourism enterprise management theory, can also be used as the theoretical basis of tourism geography.

## 4. Case Area Overview

Located in the town of Bihu, Liandu District, Lishui City, Zhejiang Province, the village of Xiananshan is a Lishui Municipal Cultural Heritage Protection Unit, with more than 40 old houses with rammed earth facades in existence, the oldest of which is more than 400 years old and was built during the Wanli period of the Ming Dynasty, making it a veritable ancient village [27]. In recent years, as the standard of living has improved, villagers have moved to live outside, and the village once became a hollow village. In order to protect the ancient village, the government has carried out two maintenance repairs on Ha Nan Shan, but it remained uninhabited and the village gradually went into decline.Nowadays, every courtyard in Ha Nan Shan is a landscape and every dwelling is a story, truly achieving “five hundred years outside, five stars inside.” The village of Xiananshan, like a pearl swaying in the town of Bihu in Lishui’s Liandu District, attracts visitors from all over the world, both vibrant and inheriting the original village culture, with its landscape layout as showed in Figure3.Figure 3

### 4.1. The Self-Organising Nature of System Evolution

The growth and evolution of the system mainly relies on the exchange of material and energy between the system and the outside world and is subject to the interaction of various internal and external dynamics, which is the result of the interaction between the system’s self-organisation and other organisations. The evolution of the state of the habitat system of the rural tourism edge of the landscape has a temporal procedure, with its own movement process of creation, development, and extinction, through the nonlinear action of various elements under the rise and fall movement, to promote the generation of a new orderly structure within the system. However, not all ups and downs will cause sudden changes in the system, small ups and downs have no direct impact on the generation of new orderly structure of the system, and it only allows the system state to deviate temporarily, as long as the system does not exceed the critical point of sudden changes, eventually will return to the original stable state. If the system continues to exchange material, energy, and information with the outside world, quantitative changes may lead to qualitative changes, and a small random disturbance may be amplified by nonlinear effects near the critical point, crossing a certain threshold, which may cause structural instability in time, space, and function of the habitat system, and the habitat system enters a new evolutionary stage (Figure4).Figure 4
Self-organisation evolutionary path.This dynamic movement process shows a strong correlation with the development process of the core landscape. In the primary stage of the development of the core scenic area, the core scenic area has absolute advantages and is extremely attractive to the development of the surrounding rural tourism areas, and the flow of tourism factors is concentrated in the core area, and the corresponding rural tourism area habitat system is in a slow and spontaneous evolutionary stage. With the development of social and economic development, the core scenic area development tends to saturate, and the corresponding flow of tourism factors began at the core scenic area around the rural area diffusion, and the continuous input of external energy and the original system gradually disintegrated and jumped to a new, stable, and orderly structure state.


### 4.2. The Cyclical Nature of System Evolution

From the perspective of the self-organised evolutionary path of the habitat system and the “core-edge” territorial structure, the evolution of the habitat system in rural tourism areas shows a strong cyclical nature. With the transformation of the tourism life cycle of the core scenic area, there is a complex energy output-input relationship between the surrounding rural tourism site habitat system and the core scenic area, and its system stability is poor:(1)dCdt=rCK−CK,where dC/dt represents the instantaneous increment of the habitat capacity of a rural tourism site, r is the growth rate of the habitat capacity of a rural tourism site, C is the existing rural habitat capacity, and K represents the saturation of the rural habitat system under a certain socioeconomic environment (the indicator varies from period to period, i.e., the threshold for the synergistic development of the system elements. In general, at r>0, the steady state of the rural habitat system changes abruptly from C=0 to C=K. At the same time, the rate of system evolution varies depending on the value of K, thus forming a different picture of system evolution (Figure 5).Figure 5
Rural tourism attractions of scenic spot edge type.When theC value is infinitely close to the K value at a certain stage, the saturation state of the period is reached, and the rural habitat system in the peripheral area is at a critical point, which is also a key stage for the government and enterprises to intervene strongly, and the threshold of the system needs to be increased K. The government can replan and develop the tourist attractions from the perspective of sustainable tourism development on a larger spatial scale and link up with the surrounding rural tourist areas for development. The government can create a second attraction in addition to the core scenic area and create a regional integrated barrier-free tourism area, while the surrounding rural tourism areas will be integrated and optimised within the system, leading to the upgrading of the structure and function of the habitat system and entering a new evolutionary cycle. Overall, the evolution of the rural habitat system shows a spiral trend. According to the system dynamics mechanism proposed by [30], it is known that the evolution of the habitat system of the rural tourist areas in the fringe area is a combination of segmented continuous logistic curves, and the combined evolution model of the system is
(2)dCdt=riC−∑j=1i−1Kj∑j=1iKj−C/Kj,i=1,2,3⋯⋯,n;j=1,2,3⋯⋯,m,whereri is the growth rate of habitat capacity at each stage and Kjis the threshold value for the jth stage of habitat evolution. Based on this mathematical model of system evolution, the trajectory of the evolution of the habitat system of the scenic fringe rural tourism site can be modelled (Figure 5).


### 4.3. Fluctuations in the Evolution of Systems

At a macrolevel, the stages of evolution, direction of evolution, and rate of evolution of the habitat system of scenic fringe rural tourism sites are closely linked to the spatial and temporal transformation of the flow of tourism elements in the core scenic area, which means that the external driving forces of the evolution of the habitat system are relatively certain, and the coupling mode, degree of action, and development trend of the two systems can also be determined. In a sense, therefore, the cyclical nature of the evolution of habitat systems in scenic fringe rural tourism is definable and predictable. The basic factors mainly refer to the natural geographical conditions, traditional farming patterns, traditional cultural customs and traditional living habits, etc. These factors, which have been accumulated over a long period of time, play a relatively stable role in the formation and development of the habitat environment in rural tourism areas, and the relationship between people and land is relatively harmonious (Figure6(a)). The new factors include the innovation of the grassroots organisational system, the introduction of national rural tourism and rural development policies, and the change of the rural land system and household registration system. These new factors accelerate the evolution of the habitat environment in rural tourism areas, and the evolution is faster, but due to the instability, complexity, and intersectionality of these new factors themselves and the process of action, the development of the habitat environment in rural tourism areas shows a certain degree of oscillation (Figure 6(b)). Mutation factors mainly refer to events with unforeseen impacts, such as the construction of major development texts for regional tourism, major pollution events in the ecological environment or natural disasters. These sudden change factors may achieve significant changes in the habitat of rural tourism sites in a relatively short period of time (Figure 6(c)).Figure 6

### 4.4. Influence Mechanisms on the Evolution of the Habitat of Rural Tourism Sites on the Edge of the Landscape

The habitat system of scenic fringe rural tourism sites is a dynamic and open composite ecosystem, and the ecological-geographical process of its evolution is more intense under the periodic stimulation of the material and energy flow of the core scenic area; therefore, it is necessary to sort out and summarize the process of the evolution of the habitat system in this typical region. The evolution of the habitat environment in rural tourism areas on the edge of the landscape follows the general rules of system evolution but at the same time has its own special requirements, which are reflected in the general trends and special dynamic mechanisms of system evolution. The structure of the habitat system is in the process of continuous evolution, and when it exceeds a certain threshold, it breaks the boundary of the original system and realises the structural upgrade and functional transformation of the system. This quantitative to qualitative spatiotemporal coupling process is driven by the spatiotemporal transformation of the flow of tourism elements, which takes the form of spatiotemporal evolution of tourism flows, capital flows, and land use patterns and the spatial structure of settlements. As the habitat environment is a composite ecosystem, its evolution process has certain similarities with the ecological community succession. Borrowing some ideas from biology, ecology, and environmental science, the spatial process of the evolution of the habitat environment in the scenic fringe-type rural tourism area is divided into four processes, namely, invasion, competition, reaction, and regulation, to build a dynamic model of the evolution of the habitat environment in the scenic fringe-type rural tourism area as shown in Figure7.Figure 7
Influence mechanism.The competition process is essentially the unification of the differentiation process and the symbiosis process of the habitat system in the core and peripheral areas. The differentiation process is the main motive force in the evolution of the habitat environment in rural tourism sites, and the symbiosis process is the key stage for the orderly development of the habitat environment in rural tourism sites. The inflow of tourism factors interferes with the self-organising function of the rural tourism habitat system, and the coupling strength of the two systems, the core scenic area and the peripheral area, hovers at the critical point of the qualitative change of the system, at which time the rural tourism habitat system is in a chaotic, disorderly, and conflicting vortex. Beyond the critical point, the various functions of the system will show the characteristics of homogeneous convergence and heterogeneous exclusion and eventually form a new state of the habitat environment in the geographical space, as showed in Figure8.Figure 8
View of the courtyard.The regulation process is to clarify the inner connection between the spatial and temporal pattern of rural habitat environment and the tourism development process and to seek the path of constructing the habitat environment of scenic fringe-type rural tourism sites. The competition process can achieve the maximization of resources and spatial value, but there are also serious divisions and social inequity. At this point, the timely intervention of other organisations can ensure the sustainable development of the habitat system in rural tourism sites, and therefore, effective regulation by the government is particularly important. Before regulation, it is necessary to summarize the process of habitat evolution and habitat effects in scenic fringe rural tourism sites, in order to provide a basis for the government’s intervention and regulation content.


## 4.1. The Self-Organising Nature of System Evolution

The growth and evolution of the system mainly relies on the exchange of material and energy between the system and the outside world and is subject to the interaction of various internal and external dynamics, which is the result of the interaction between the system’s self-organisation and other organisations. The evolution of the state of the habitat system of the rural tourism edge of the landscape has a temporal procedure, with its own movement process of creation, development, and extinction, through the nonlinear action of various elements under the rise and fall movement, to promote the generation of a new orderly structure within the system. However, not all ups and downs will cause sudden changes in the system, small ups and downs have no direct impact on the generation of new orderly structure of the system, and it only allows the system state to deviate temporarily, as long as the system does not exceed the critical point of sudden changes, eventually will return to the original stable state. If the system continues to exchange material, energy, and information with the outside world, quantitative changes may lead to qualitative changes, and a small random disturbance may be amplified by nonlinear effects near the critical point, crossing a certain threshold, which may cause structural instability in time, space, and function of the habitat system, and the habitat system enters a new evolutionary stage (Figure4).Figure 4
Self-organisation evolutionary path.This dynamic movement process shows a strong correlation with the development process of the core landscape. In the primary stage of the development of the core scenic area, the core scenic area has absolute advantages and is extremely attractive to the development of the surrounding rural tourism areas, and the flow of tourism factors is concentrated in the core area, and the corresponding rural tourism area habitat system is in a slow and spontaneous evolutionary stage. With the development of social and economic development, the core scenic area development tends to saturate, and the corresponding flow of tourism factors began at the core scenic area around the rural area diffusion, and the continuous input of external energy and the original system gradually disintegrated and jumped to a new, stable, and orderly structure state.


## 4.2. The Cyclical Nature of System Evolution

From the perspective of the self-organised evolutionary path of the habitat system and the “core-edge” territorial structure, the evolution of the habitat system in rural tourism areas shows a strong cyclical nature. With the transformation of the tourism life cycle of the core scenic area, there is a complex energy output-input relationship between the surrounding rural tourism site habitat system and the core scenic area, and its system stability is poor:(1)dCdt=rCK−CK,where dC/dt represents the instantaneous increment of the habitat capacity of a rural tourism site, r is the growth rate of the habitat capacity of a rural tourism site, C is the existing rural habitat capacity, and K represents the saturation of the rural habitat system under a certain socioeconomic environment (the indicator varies from period to period, i.e., the threshold for the synergistic development of the system elements. In general, at r>0, the steady state of the rural habitat system changes abruptly from C=0 to C=K. At the same time, the rate of system evolution varies depending on the value of K, thus forming a different picture of system evolution (Figure 5).Figure 5
Rural tourism attractions of scenic spot edge type.When theC value is infinitely close to the K value at a certain stage, the saturation state of the period is reached, and the rural habitat system in the peripheral area is at a critical point, which is also a key stage for the government and enterprises to intervene strongly, and the threshold of the system needs to be increased K. The government can replan and develop the tourist attractions from the perspective of sustainable tourism development on a larger spatial scale and link up with the surrounding rural tourist areas for development. The government can create a second attraction in addition to the core scenic area and create a regional integrated barrier-free tourism area, while the surrounding rural tourism areas will be integrated and optimised within the system, leading to the upgrading of the structure and function of the habitat system and entering a new evolutionary cycle. Overall, the evolution of the rural habitat system shows a spiral trend. According to the system dynamics mechanism proposed by [30], it is known that the evolution of the habitat system of the rural tourist areas in the fringe area is a combination of segmented continuous logistic curves, and the combined evolution model of the system is
(2)dCdt=riC−∑j=1i−1Kj∑j=1iKj−C/Kj,i=1,2,3⋯⋯,n;j=1,2,3⋯⋯,m,whereri is the growth rate of habitat capacity at each stage and Kjis the threshold value for the jth stage of habitat evolution. Based on this mathematical model of system evolution, the trajectory of the evolution of the habitat system of the scenic fringe rural tourism site can be modelled (Figure 5).


## 4.3. Fluctuations in the Evolution of Systems

At a macrolevel, the stages of evolution, direction of evolution, and rate of evolution of the habitat system of scenic fringe rural tourism sites are closely linked to the spatial and temporal transformation of the flow of tourism elements in the core scenic area, which means that the external driving forces of the evolution of the habitat system are relatively certain, and the coupling mode, degree of action, and development trend of the two systems can also be determined. In a sense, therefore, the cyclical nature of the evolution of habitat systems in scenic fringe rural tourism is definable and predictable. The basic factors mainly refer to the natural geographical conditions, traditional farming patterns, traditional cultural customs and traditional living habits, etc. These factors, which have been accumulated over a long period of time, play a relatively stable role in the formation and development of the habitat environment in rural tourism areas, and the relationship between people and land is relatively harmonious (Figure6(a)). The new factors include the innovation of the grassroots organisational system, the introduction of national rural tourism and rural development policies, and the change of the rural land system and household registration system. These new factors accelerate the evolution of the habitat environment in rural tourism areas, and the evolution is faster, but due to the instability, complexity, and intersectionality of these new factors themselves and the process of action, the development of the habitat environment in rural tourism areas shows a certain degree of oscillation (Figure 6(b)). Mutation factors mainly refer to events with unforeseen impacts, such as the construction of major development texts for regional tourism, major pollution events in the ecological environment or natural disasters. These sudden change factors may achieve significant changes in the habitat of rural tourism sites in a relatively short period of time (Figure 6(c)).Figure 6

## 4.4. Influence Mechanisms on the Evolution of the Habitat of Rural Tourism Sites on the Edge of the Landscape

The habitat system of scenic fringe rural tourism sites is a dynamic and open composite ecosystem, and the ecological-geographical process of its evolution is more intense under the periodic stimulation of the material and energy flow of the core scenic area; therefore, it is necessary to sort out and summarize the process of the evolution of the habitat system in this typical region. The evolution of the habitat environment in rural tourism areas on the edge of the landscape follows the general rules of system evolution but at the same time has its own special requirements, which are reflected in the general trends and special dynamic mechanisms of system evolution. The structure of the habitat system is in the process of continuous evolution, and when it exceeds a certain threshold, it breaks the boundary of the original system and realises the structural upgrade and functional transformation of the system. This quantitative to qualitative spatiotemporal coupling process is driven by the spatiotemporal transformation of the flow of tourism elements, which takes the form of spatiotemporal evolution of tourism flows, capital flows, and land use patterns and the spatial structure of settlements. As the habitat environment is a composite ecosystem, its evolution process has certain similarities with the ecological community succession. Borrowing some ideas from biology, ecology, and environmental science, the spatial process of the evolution of the habitat environment in the scenic fringe-type rural tourism area is divided into four processes, namely, invasion, competition, reaction, and regulation, to build a dynamic model of the evolution of the habitat environment in the scenic fringe-type rural tourism area as shown in Figure7.Figure 7
Influence mechanism.The competition process is essentially the unification of the differentiation process and the symbiosis process of the habitat system in the core and peripheral areas. The differentiation process is the main motive force in the evolution of the habitat environment in rural tourism sites, and the symbiosis process is the key stage for the orderly development of the habitat environment in rural tourism sites. The inflow of tourism factors interferes with the self-organising function of the rural tourism habitat system, and the coupling strength of the two systems, the core scenic area and the peripheral area, hovers at the critical point of the qualitative change of the system, at which time the rural tourism habitat system is in a chaotic, disorderly, and conflicting vortex. Beyond the critical point, the various functions of the system will show the characteristics of homogeneous convergence and heterogeneous exclusion and eventually form a new state of the habitat environment in the geographical space, as showed in Figure8.Figure 8
View of the courtyard.The regulation process is to clarify the inner connection between the spatial and temporal pattern of rural habitat environment and the tourism development process and to seek the path of constructing the habitat environment of scenic fringe-type rural tourism sites. The competition process can achieve the maximization of resources and spatial value, but there are also serious divisions and social inequity. At this point, the timely intervention of other organisations can ensure the sustainable development of the habitat system in rural tourism sites, and therefore, effective regulation by the government is particularly important. Before regulation, it is necessary to summarize the process of habitat evolution and habitat effects in scenic fringe rural tourism sites, in order to provide a basis for the government’s intervention and regulation content.


## 5. Conclusions

Based on the theory of system theory and human-land relationship, the system characteristics of the habitat environment of rural tourism sites in the edge of scenic areas are summarized in three aspects, including self-organisation, periodicity, and fluctuation of system evolution. This cyclical fluctuation is influenced by many factors and presents uncertainty and diversity in the evolutionary path and rate.Drawing on some concepts from biology, ecology, and environmental science, the process of habitat evolution in rural tourism sites on the edge of scenic areas is divided into four processes, namely, invasion, competition, reaction, and regulation, and a dynamic model of habitat evolution in rural tourism sites on the edge of scenic areas is constructed.
