Assessing Urban Tourism Resource Ecological Carrying Capacity: A “Desired-Undesired” Dual Perspective Approach
Authors: Yang Rui , Xiong Yuan , He Hongman , Liu Yu 
Published: November 2024

AbstractThis study introduces a new approach to evaluate the ecological carrying capacity of urban tourism resources (UTRECC), emphasizing the perspectives of “desired” and “undesired”. Based on urban sustainability principles, this study categorizes the load of urban tourism resources into “desired load” and “undesired load”. Using tourism system theory, the study examines the carriers of four key subsystems related to urban tourism resource carrying capacity, including tourism attraction carrier, atmospheric environmental support carrier, waterbody environmental support carrier, and land environmental support carrier. A calculation model for UTRECC is constructed based on 11 carrier indicators and 5 load indicators. This method elucidates the performance of ecological carriers in urban tourism, suggesting that, within certain parameters, a higher carrying capacity index is preferable. Empirical research was conducted in four case cities: Beijing, Shanghai, Chengdu, and Guangzhou. The results reveal significant variations in the tourism resource carrying capacities of these cities, with Beijing and Shanghai exhibiting relatively higher capacities compared to Chengdu and Guangzhou. The findings offer valuable insights for the planning, development, and management of urban tourism, providing a robust framework for future assessments and adjustments of urban resources.
Study on the Spatial Interaction of Habitat Quality Pattern and Thermal Environment Based on InVEST—A Case Study of the Guangdong-Hong Kong-Macao Greater Bay Area
Authors: Wang Jiayu 
Published: November 2024

AbstractWith China’s urbanization advancing into an advanced phase, urban clusters experiencing swift expansion of urban land have emerged as “disaster areas” where ecological environment problems are highly concentrated. Therefore, paying attention to the habitat quality of urban agglomerations and their ecological cooling effect is crucial for improving the quality of the living environment and fostering sustainable development in the region. This research uses the Guangdong-Hong Kong-Macao Greater Bay Area (GHM-GBA) as a case study, applies the InVEST platform, Geographic Information System (GIS), and Binary Moran’s I index, and undertakes an investigation into the spatial interplay between the habitat quality pattern and the thermal environment within the urban clusters of the GHM-GBA between 2000 and 2020. Firstly, utilizing data on habitat threat density, the Habitat Quality Module on the InVEST platform is employed to measure the habitat quality and degradation extent of urban agglomerations. Secondly, based on MODIS satellite sensor data, the surface temperature is inverted and interpreted, and the spatial heterogeneity traits of the urban agglomeration’s thermal environment are examined. Then, the Binary Moran’s I index is used to clarify the spatial clustering and spatial dispersion relationship characteristics between habitat quality and thermal environment, including the network spatial distribution of regions with positive spatial correlation and negative spatial correlation. Ultimately, through the lens of urban design, this paper puts forward detailed planning recommendations to improve the quality of living spaces and thermal comfort within urban clusters. These suggestions serve as a reflection for the ecological sustainability, livability, and high-quality growth of the GHM-GBA.

Authors: Li Yichen , Jing Xiaoting 
Published: November 2024

AbstractWind, as one of the important elements of urban microclimate, plays a crucial role in the dispersion of air pollutants. Adequate improvement should be made to mitigate the impact of urban spaces on the wind environment. Green spaces along pedestrian streets are an essential component of the public activity space system, accommodating most outdoor communication activities for citizens. However, the design of existing green spaces along pedestrian streets is often based on past experience, lacking empirical research on the relationship between green spaces, wind environment, and pollutant dispersion. Therefore, the correlation research between tree array space and PM2.5 pollutant distribution in the air, and how to optimize the layout of tree array space by design means according to its distribution regularities, are the main research contents presented in this paper. Taking two important green spaces in Jiefangbei pedestrian street of Chongqing as the sample points for research, this paper adopts the methods of measurement and numerical simulation. Firstly, the pollutant concentration and wind environment in the green space are measured and analyzed, and then use the PHOENICS tool to simulate and compare the wind environment of the green space in the study area before and after optimization design. The results show that the concentration of pollutants is usually high in green space as the greening has aggregation of pollutants to itself; An obvious negative correlation is found between wind speed and the concentration of pollutants, good ventilation is an important means to alleviate the air with low quality; Reasonable design of tree array space based on microclimate can effectively improve the air quality in local space.

Published: November 2024

AbstractWith the rapid development of China’s social economy and the continuous improvement of urbanization, a range of issues impacting the quality of community spaces have emerged, including inadequate transportation, environmental degradation, insufficient amenities, housing and employment imbalances, as well as limited recreational areas. Consequently, there is an inherent public desire to establish healthy and livable communities that offer comfort, convenience, safety, and aesthetic appeal. This study examines the correlation between new urbanism and the concept of community environment livability by constructing an evaluation index system and model to quantitatively analyze Mianyang old city’s overall level of community environment livability along with its influencing factors. Additionally, it summarizes various types of communities in terms of their spatial distribution and characteristics while proposing optimization strategies tailored to each type. The results of this study show that: (1) the livability of Mianyang Old city community decreases gradually from south to north, from east to west, and there is a big difference between the south and north. The areas with high livability evaluation value are concentrated in the central area of the old city, while the “poor” area is distributed in the western fringe area; (2) The service facilities and living environment of the old city community are highly valued, while the employment and public leisure areas need to be improved; (3) The 28 communities can be divided into five types: “environment improvement type, quality optimization type, basic improvement type, housing security type and function repair type”, and the optimization strategy is proposed.

Effects of the Built Environment on Physical Activity in the Elderly: A Comparative Study Based on Machine Learning and Logistic Regression
Authors: Mu Junbo , Zhang Peng , Wang Xiaoping 
Published: November 2024

AbstractIn China, a conspicuous disparity exists among the built environments within urban and rural areas and the lifestyle requirements of the elderly, presenting a notable social issue. Throughout the urbanization process, the built environments in both urban and rural regions may not sufficiently address the preferences and requirements of the elderly demographic. This deficiency may encompass shortcomings in public transportation infrastructure, community services, and other aspects, consequently constraining the social engagement and activity scope of the elderly population. Despite the built environment at the community level being conducive to social interaction and physical activity among the elderly, the reality often deviates from their needs. Challenges such as insufficient pedestrian pathways, parks, and fitness facilities may impede the eagerness and capability of the elderly to actively participate in community life. To address these challenges, this study employed the Adaboost iterative algorithm and traditional logistic regression analysis to comprehensively grasp the influence of the constructed environment on the well-being of older adults. Through an examination of factors such as physical activity levels, dietary intake, and social interaction among the elderly, it was discerned that the built environment significantly influences the physical activity of older individuals, particularly in factors such as population density and residential areas. Additionally, a close correlation was observed between the built environment and the dietary intake of the elderly, indicating the potential influence of the built environment on their lifestyle. However, it is noteworthy that besides built environment factors, social demographic factors also play a pivotal role in determining social interaction among the elderly. This suggests that when considering the living environment of the elderly, attention should not solely be directed towards enhancing physical surroundings but also towards comprehending the influence of social environments on their lives. Therefore, future research endeavors should further propose strategic recommendations for creating “age-friendly” and "aging in one’s original place” environments in urban and rural areas of China, aiming to better address the diverse needs of the elderly and provide a more scientifically grounded basis for relevant policy-making.

AbstractThe situation of aging in China is becoming increasingly severe. As one of the main daily activity spaces for the elderly, community parks carry the function of meeting the activity needs of the elderly, affecting their choices of different physical leisure activities, and thus affecting their physical health and emotional perception. Faced with the problems of low-quality community park environment, lack of recreational facilities, and unreasonable layout of recreational spaces, how to build a livable and healthy community park environment for the elderly needs further detailed exploration. Under the guidance of the healthy aging strategy, multiple evaluation indicators were selected based on domestic and foreign literature. Three typical community parks in Chengdu were taken as research samples, and 218 scale questionnaires were collected as data basis. The SEM model was constructed by combining SPSS and Amos software for analysis. The results show that the built environment of community park recreation space has a positive impact on the emotional perception of the elderly through leisure interaction activities and sports and fitness activities, and all factors are interrelated. The three latent variables of service environment, accessibility and equipment are the most important influencing factors for the elderly to engage in leisure physical activities, among which the service environment has the most significant influence, which proves that the elderly pay more attention to the comfort of seats, the location distribution of activity squares, fitness facilities, shading facilities, seats, public toilets, pavilions and garbage cans when engaging in leisure physical activities. Promoting the construction of community parks suitable for the elderly is practically important. Finally, the paper puts forward some strategic suggestions for urban planning and design.
