基于熵权TOPSIS的湖北省城市人居环境质量时空分异研究

城市人居环境质量评价是改善城市人居环境质量、促进城市健康可持续发展的重要基础.该文以湖北省为研究区，从城市人居生活质量、生产质量和生态质量3方面选取18个指标构建城市人居环境质量评价指标体系，采用熵权TOPSIS法和地理探测器模型对湖北省17个市州2013—2018年的城市人居环境质量时空分异及贡献因素进行研究.结果表明： 1) 研究期内湖北省城市人居环境及其生活、生产和生态子系统质量总体上呈提升趋势，各地市州城市人居环境及其生活、生产、生态子系统质量的差距总体上呈缩小趋势；2) 湖北省城市人居环境质量在空间上呈现出“核心集聚、局部连片”的分布特征，且研究期内鄂西地区人居环境质量改善速度最快，鄂中地区次之，鄂东地区最小；3) 规模以上工业企业数密度、人均社会消费品零售总额、人均固定资产投资、城镇化率、公路里程密度是驱动湖北省城市人居环境质量提升的主要贡献因子，但随着时间演变，城市人居环境质量提升的重心将由少数的核心因子向多因子共建转变.

Research on temporal and spatial differentiation of urban human settlement environment quality in Hubei Province based on entropy TOPSIS

The evaluation of the quality of urban human settlements is an important foundation for improving the quality of urban human settlements and promoting the healthy and sustainable development of cities. In this paper takeing Hubei Province as the research area and selecting 18 indicators from three aspects of urban human settlement quality， production quality and ecological quality， an urban humansettlement environment quality evaluation index system is constructed. The entropy weight TOPSIS method and the geographic detector model are used to analyze the spatial-temporal differentiation and contributing factors of urban human settlement environment quality in 17 cities and prefecture in Hube Province from 2013 to 2018. The results are shown as follows. 1) During the study period， the quality of urban human settlements in Hubei Province and the quality of its life， production and ecological environment subsystems have been continuously improved， and the quality of urban human settlements in various cities and prefectures has been narrowing. 2) The quality of urban human settlements in Hubei Province has been improving in terms of space， presenting the distribution characteristics of “core agglomeration and local contiguousness”. During the study period， the human settlement environment quality has improved at the fastest rate in western Hubei， followed by central Hubei， and eastern Hubei is the smallest. 3) Per capita investment in fixed assets， total retail sales of consumer goods per capita， urbanization rate， number density of industrial enterprises above designated size， and highway mileage density are the areas that have improved the most during the study period. However， as time evolves， the quality of urban human settlements has improved. The focus will shift from a few core factors to multi-factor co-construction.
