## 1 Introduction
Cultural zoning of these areas and the delineation of regions with similar cultural landscapes enable a deeper understanding of the diversity of cultural landscapes from a regional perspective. This, in turn, will provide scientific guidance for the protection of various types of traditional villages. Therefore, elucidating the characteristics of different cultural landscapes in villages and further investigating the patterns of cultural landscape differentiation across zones can offer valuable scientific insights and references for regionalized cultural heritage protection and sustainable development on a global scale. In light of the aforementioned points, both Chinese and international scholars have conducted extensive research and achieved significant findings in the domain of cultural landscapes and cultural landscape zoning. In terms of research scale, international researchers primarily adopt a macro-level perspective [19], utilizing the comprehensive attributes of cultural landscapes as criteria for broad zoning, but they often overlook studies at smaller scales such as the provincial and regional levels. In contrast, research on the cultural landscape zoning of villages in China predominantly emphasizes these smaller scales [20,21], focusing on typical cultural core areas, while cultural intermingling zones have received limited attention. Cultural intermingling regions are defined as transitional areas where multiple cultural circles converge, characterized by intricate natural geography and notable cultural diversity. This rich and varied nature renders the traditional villages and residential cultural landscapes in these intermingled areas exceptionally complex, making the analysis of their landscape characteristics and differentiation patterns more challenging compared to cultural core areas. In terms of research methodology, most studies remain qualitative and gradually integrate quantitative approaches. Qualitative research is mainly based on the descriptive method, the dominant factor method [22], and the landscape gene mapping method [23]. Among these, the landscape gene mapping method involves scholars introducing the biological concept of genes into traditional villages, thereby proposing the theory of village cultural landscape genes [24]. This method, along with geographical methods such as 3S (Geographic Information Systems, Remote Sensing, and Global Positioning Systems), spatial syntax [25], and complex adaptive systems (CAS) [26], as well as the gene chain method [27], is used to analyze traditional villages and propose research methods for identifying and mapping the cultural landscape genes of traditional villages. The quantitative and qualitative combined method mainly adopts the hierarchical analysis method and the geographic information systems combined method [20], as well as clustering methods to calculate village similarity [28]. Throughout the current research, the content has gradually expanded, but the research scale and research methodology have certain deficiencies. Firstly, the predominant focus of traditional village landscape research in China is on cultural core areas, the marginalized cultural integration areas in academic discourse. Recognizing the interdependent and complementary relationship between cultural core areas and integration zones; neglecting the latter results in a fragmented research framework for traditional villages. Therefore, it is imperative to broaden the research scope to encompass multicultural integration areas to enhance the overall research framework concerning villages and residential environments. Consequently, there is an urgent need to expand the research system for villages and dwellings to include areas of multicultural intermingling. Secondly, although quantitative research has been conducted on the selection of \"dominant factors\", methods such as the \"Delphi Method\" and \"Hierarchical Analysis Method\" are used to determine the superimposed weights.
