基于高分辨率数据的农村居民点分布格局及影响因素研究
Research on the Distribution Patterns and Influencing Factors of Rural Settlement Based on High Resolution Data
摘要
Abstract
[Objective]The aims of this study are to analyze the characteristics of large-area distribution of rural settlements in southwest China from a high-resolution perspective,to explore the influence of different factors on the spatial distribution of rural settlements,and to provide a scientific basis for the spatial development of rural settlements.[Methods]With respect to the prevailing research inadequacies that struggle to balance'regional rules'with'internal fine structure',this study leveraged high-resolution rural settlement data,utilized kernel density,spatial hotspot detection,accessibility analysis,and geographic detectors to analyze the spatial distribution of rural settlements in Guangxi.At both global and patch scales,we investigated the spatial distribution characteristics of rural settlements,further analyzed the impact of natural,locational,and socio-economic factors on this spatial distribution.[Results](1)The overall distribution of rural settlements in the study area was significantly clustered,mainly characterized by small-scale,low-density,and complex shapes.The average density of rural settlements throughout the province was 5.59 per km2,with both scale and shape exhibiting significant clustering features of high values.(2)The distribution of rural settlements demonstrated notable differentiation.With the increase of elevation and slope,as well as the decrease of accessibility to farmland,roads,and water areas,the total area,scale,and density of rural settlements showed a declining trend.There was a large disparity in the spatial distribution of settlements under different geological backgrounds.Rural settlements in karst areas had a smaller total area but larger scale,more complex shape,and lower density.(3)Different factors such as natural,locational,and socio-economic variables had distinctly different influences on the distribution of rural settlements.Socio-economic factors had a strong'determining power'on the total area of rural settlement distribution.Locational factors,namely farmland and roads,played a dominant role in the scale and shape of rural settlement distribution.In contrast,natural factors exerted the most significant influence on the distribution density of rural settlements.[Conclusion]The spatial distribution of rural settlements in Guangxi has significant regional differences,and different factors have significant effects on rural settle-ments.关键词
