广东省县域乡村人居环境质量评价及其影响因素

Spatial Distribution and Influencing Factors of Rural Human Settlement Quality in Guangdong Province

以县域尺度为研究单元,构建乡村人居环境质量评价指标体系,采用全排列多边形指数、GIS空间分析、空间计量模型等方法探讨广东省县域乡村人居环境的空间分异及其影响因素。结果表明:广东省县域乡村人居环境质量空间差异显著,两极分化明显,其中高值区集中在珠三角近郊区,低值区主要分布在经济落后的偏远贫困县;各子系统间差异明显,类型以一般、良好为主,且各分项子系统空间分异由大到小依次为经济发展>生产生活>生态环境;从影响因素看,人口集聚对乡村人居环境质量为负向效应,经济发展水平、产业结构状况、基础设施建设、公共服务保障、生态环境治理等均为正向促进作用,其中经济发展水平是影响乡村人居环境质量空间分异的主导因素。

Taking the county scale as the research unit,this paper constructs the quality evaluation index system of rural human settlements,and discusses the spatial differentiation and influencing factors of rural human settlements in Guangdong Province by using the the fully arrayed polygon aggregate index method,spatial analysis method of ArcGIS,and spatial regression model.The results show that:there are significant spatial differences and polarization in the quality of rural human settlements in counties of Guangdong Province,in which the high-value areas are concentrated in the suburbs of the Pearl River Delta,and the low-value areas are mainly distributed in remote and poor counties with backward economy.There are obvious differences among subsystems,and the main types are general and good,the spatial differentiation features of each subsystem are different,the order is:economic development>living-production>ecological environment.From the perspective of influencing factors,population agglomeration has a negative effect on the quality of rural human settlements,and the level of economic development,industrial structure,infrastructure construction,public service guarantee and ecological environment governance all play a positive role.Among them,the level of economic development is the primary factor that affects the spatial differentiation of rural human settlements.
