江苏省城市人居环境质量的空间格局

Spatial Distribution Pattern of Urban Human Settlement Environment in Jiangsu Province

以居住环境、社会经济环境、公共服务环境、生态环境4个一级指标,以及24个二级指标构建了城市人居环境质量的综合评价指标体系,运用不平衡分析、熵值法、相关分析等方法研究了江苏省城市人居环境质量的空间分异格局.结果表明:1)江苏省城市人居环境质量相对于人口规模呈现出不平衡局面.2)城市人居环境质量总体和各类水平均呈现自南向北递减的特征.3)江苏省城市人居环境质量的差异与经济发展水平的相关性较高,但城市人居环境质量的区域差异程度远低于经济发展水平的区域差异程度.

Human settlements are the foundation and carder for a city to realize its sustainable development. In this study a comprehensive evaluation system of urban human settlements was set up with 4 first-level indexes and 24 second-level indexes, including the living, socio-economic environments, public service environments, and ecological environments. Methods of disequilibrium analysis, standard deviation, entropy, differentiation coefficient were employed to study the spatial differentiation on urban human settlement environment in Jiangsu province. The results indicated that： Firstly, in contrast with the urban population size, the level of the urban human settlements in Jiangsu Province demonstrates an imbalance situation. Secondly, the overall and each kind of level of the urban human settle- ment quality take on the degressive distribution characteristic from south to north. Finally, the level of economic development has a high correlation to the difference on the level of the urban human settlements in Jiangsu Province. Besides, the degree of the regional difference of urban human settlements＇ level is far lower than that of the economic development.
