“三生”视角下长沙市城市空间宜居性评价

Evaluation of the Livability of Urban Space In Changsha from the Perspective of “Production-Living-Ecology”

基于“三生”视角建立城市空间宜居性评价指标体系,通过空间分析方法从宜居性综合程度、单因素空间分异现状和耦合度分析长沙市城市空间宜居性,结果表明:(1)生产、生活、生态单因素宜居性程度空间分异特征明显;(2)城市空间综合宜居程度较高,空间分布上呈现出“大分散,小集聚”特征,宜居程度高的地区集中在中心城边缘区;(3)生产、生活、生态间的耦合度存在较大差异,其中耦合度最高的是“生产—生活”,呈现一定的空间错位。

Based on the perspective of“Production-Living-Ecology”,this work establishes an evaluation index system about urban space livability.The spatial analysis method is employed to analyze the livability of urban space in Changsha from the comprehensive degree of livability,the status of single factor spatial differentiation,and the degree of the coupling.Our results show that(1)characteristics of the spatial differentiation of production,living and ecological single factor livability are manifest;(2)urban spatial comprehensive livability is high,the spatial distribution shows the feature of“large dispersion and small agglomeration”,and concentrated areas with high livability are located in the edge area of the center city;and(3)there is a large difference in the coupling degree between production,living and ecology.The highest degree of the coupling is between production and living,which exhibits a certain degree of spatial delocalization.
