西部地区国家乡村振兴重点帮扶县空间分布及影响因素

Spatial Distribution and Influencing Factors of Key Counties for Rural Revitalization in Western China

以西部地区160个国家乡村振兴重点帮扶县为研究对象,运用GIS空间分析等方法探析重点帮扶县的空间分布特征及影响因素。结果表明:(1)西部地区重点帮扶县为凝聚分布类型,从省域尺度来看,重点帮扶县的空间分布呈不均衡特征,70%以上的重点帮扶县分布在云南、四川、甘肃、贵州和广西5省(区)。(2)西部地区重点帮扶县整体上呈南密北疏的空间分布格局,主要形成川西南-桂西北、陇东南-宁西南两大高密度集聚片区。(3)西部地区重点帮扶县的空间分布是海拔高程、经济发展水平、区位交通和政策导向因素耦合的结果。

This paper takes 160 key counties for rural revitalization in western China as the research object, and uses GIS spatial analysis to analyze the spatial distribution characteristics and influencing factors of key counties.The results show that:(1) The key aid counties in the western region belong to the cohesive distribution type.From the provincial scale, the spatial distribution of the key aid counties is unbalanced, and more than 70% of the key aid counties are distributed in Yunnan, Sichuan, Gansu, Guizhou and Guangxi.(2) As a whole, the key counties in the western region are densely distributed in the south and sparsely distributed in the north, mainly forming two highdensity cluster areas: southwestSichuan, northwestGuangxi and southeastGansu, southwestNanjing.(3) The spatial distribution of key counties in the western region is the result of the coupling of altitude, economic development level, regional transportation and policy guidance factors.
