Spatial evolution and driving factors of rural settlements in the plateau lake area in central Yunnan
[Objective]The aims of this study are to analyze the evolution mechanism of rural settlement spatial patterns in the plateau lake area in central Yunnan,and to offer insights into regional rural development and spatial governance.[Methods]Ripley's K function for kernel density estimation to determine bandwidth,alongside the coefficient of variation of Voronoi diagrams,landscape indices,hot spot analysis,and other methodologies were used to examine the evolution characteristics of rural settlement spatial patterns from 1995 to 2020.Subsequently,the optimal parameters-based geographical detector model was employed to analyze the driving factors.[Results](1)The spatial pattern of rural settlements in the plateau lake area in central Yunnan generally exhibited the evolution traits of quantity increase-land expansion-local contraction.(2)Topography emerged as the predominant factor influencing the spatial distribution of rural settlements in the lake area.The interplay of social and economic factors continued to propel the evolution of settlement space,delineating stage characteristics linked to the urbanization process.(3)During the middle and late stages of urbanization,the spatial differentiation of rural settlements in each lake area escalated,with aggregation and contraction coexisting.[Conclusion]In the context of rural revitalization,it is essential to steer the functional transformation of rural areas in alignment with the developmental trajectories of individual lake regions.This involves enhancing the intensive utilization of rural construction land,safeguarding arable land,and promoting ecological restoration.Additionally,it is crucial to investigate optimal village layouts and land use strategies in regions experiencing population decline,ensuring sustainable rural development.
