基于MGWR的乡村聚落演变特征及其影响因素研究
Research on the evolution characteristics and influencing factors of rural settlements based on MGWR:taking Wuyuan County as an example
摘要
Abstract
Clarifying the factors affecting the evolution of rural settlements is the basis for optimizing the spatial pattern of rural settlements.Taking Wuyuan County as the research area,this study uses methods such as landscape pattern index and hot and cold spot analysis to reveal the evolution characteristics of rural settlements in Wuyuan County,and uses a multi-scale geographically weighted regression model to analyze the factors affecting the evolution of rural settlements.The results show that the rural settlements in the study area show significant spatial heterogeneity characteristics of"dense in the middle and sparse around,dense in the south and sparse in the north",showing significant spatial positive correlation,and forming high-high clusters with Ziyang Town as the center;the multi-scale geographically weighted regression model shows the best performance in explaining the evolution of rural settlements.The role of each factor has obvious spatial non-stationarity and scale effect differences.The role of terrain relief and population density is at the micro scale,and grain production is a meso-scale factor.The distance to medical and health care facilities and village land size play a role at the global scale.The spatial optimization of rural settlements should consider the scale effect of influencing factors and build a multi-scale differentiated regulation system.关键词
