湖南省城乡融合发展的时空格局与响应过程

Spatio-temporal Pattern and Response Process of Urban-rural Integration Development in Hunan Province

城乡融合发展是城乡关系的高级形态和必然趋势,探究湖南省城乡融合发展的基本规律,对协调全省城乡关系、助推乡村振兴、实现高质量发展具有重要意义。采用主成分分析、聚类分析和地理信息系统(GIS)方法,探讨基于全省14个市州的城乡融合发展时空演变格局及响应模式。结明表明:全省各市州城乡融合发展水平普遍较低,其中城乡经济融合与城乡社会融合发展水平是城乡差距扩大的主要原因;全省不同地区城乡融合发展水平表现出一定的空间集聚性,可将湖南省内各市州城乡融合发展水平由高到低依次分为4类,Ⅰ类为益阳,Ⅱ类包括常德、永州,Ⅲ类包括株洲、邵阳、娄底、岳阳、张家界、湘西、湘潭、郴州、衡阳、长沙,Ⅳ类为怀化;2016—2022年,湖南全省各市州的城乡融合发展差距呈扩大趋势,且在湖南中北部地区与西部地区分别存在“高-高”“低-低”的空间集聚中心。

The urban-rural integration development is the advanced form and inevitable trend of urban-rural relationship.Exploring the basic laws of urban-rural integration development in Hunan Province is of great significance to coordinate the urban-rural relationship,boost rural revitalization and achieve high-quality development.Principal component analysis,cluster analysis and geographic information system(GIS)analysis methods are adopted to explore the spatio-temporal evolution pattern and response mode of urban-rural integration development based on 14 cities and prefectures in the province.The results show that the level of urban-rural integration development in cities and prefectures in the province is generally low,and the level of urban-rural economic integration and urban-rural social integration development is the main reason for the expansion of the urban-rural gap.The level of urban-rural integration development in different regions of the province shows a certain spatial agglomeration,and the level of urban-rural integration development in cities and prefectures in Hunan Province can be divided into four categories from high to low:class I is Yiyang,class II includes Changde and Yongzhou,class III includes Zhuzhou,Shaoyang,Loudi,Yueyang,Zhangjiajie,Xiangxi,Xiangtan,Chenzhou,Hengyang,Changsha,and class IV is Huaihua.From 2016 to 2022,the gap of urban-rural integration development in cities and prefectures in Hunan Province is expanding,and there are“high-high”and“low-low”spatial agglomeration centers in central,northern and western regions of Hunan Province respectively.
