摘要

[目的] 研究人居环境适宜性在时空尺度上的变化和驱动性因素，为城市建设和人居环境改善提供理论依据。[方法] 以江苏省为研究对象，构建由社会、经济、生态和建设环境4个维度组成的评价指标体系，采用熵值法、趋势分析法、地理探测器法等对2009，2013和2017年江苏省65个县域的人居环境适宜性进行定量评价研究。[结果] ①江苏省人居环境适宜性空间分异显著，总体呈现出“局部连片”，自南至北逐渐递减的空间分布特征。空间变化上，人居环境适宜性自南至北递减的空间分层显著度降低，中高水平、中水平和低水平地区连片分布趋势减弱。②2009，2013和2017年的江苏省人居环境适宜性的平均得分和变异系数分别为0.432，0.475，0.494和0.179，0.192，0.165。研究末期95.38%县域的人居环境适宜性得分上升，人居环境县级区域性差异减小。研究期间内，苏南地区各县域人居环境适宜性排名较稳定，苏中和苏北地区波动性显著。③地理探测研究表明，经济环境是江苏省人居环境适宜性演变的主要驱动力，社会和建设环境是关键动力，生态环境是次要动力。[结论] 未来江苏省应扩大经济规模，刺激消费水平，促进经济发展及均等化，并主要通过缓解老龄化危机，加强区域人口资源流动，降低工业污染物排放量，提高空气质量等方面加强人居环境建设。

Abstract

[Objective] The changes and driving factors of the suitability of human settlement on the temporal and spatial scale were studied in order to provide theoretical basis for urban construction and improvement of living environment.[Methods] Jiangsu Province was selected as the research object. An evaluation index system composed of four dimensions:social

economic

ecological

and construction environment was constructed

and entropy

trend analysis

and geographical detector methods were used to quantitatively evaluate the suitability of living environment in 65 counties in Jiangsu Province in 2009

2013

and 2017.[Results] ① The spatial differentiation of the suitability of human settlements in Jiangsu Province was significant

and was overall "locally contiguous" with a gradual decline from south to north. In terms of spatial change

the spatial stratification degree of the suitability of living environment declined significantly from south to north

and the trend of the contiguous distribution in the medium-high level

medium level

and low-level areas weakened. ② The average score and variation coefficient of the suitability of living environment in Jiangsu Province in 2009

2013

and 2017 were 0.432

0.475

0.494 and 0.179

0.192

0.165

respectively. The score of suitability of living environment increased in 95.38% counties

and the regional difference in residential environment decreased at the end of the study. During the study period

the suitability of the living environment of the counties in Southern Jiangsu Province was relatively stable

while that of the counties in Middle and Northern Jiangsu Province fluctuated significantly. ③ Geographical exploration showed that the economic

social

and construction environment was the main driving factor behind the evolution of the suitability of living settlements in Jiangsu Province

while ecological environment was the secondary driving factor.[Conclusion] To improve the living environment

Jiangsu Province should expand the economic scale

stimulate the consumption level

promote the economic development and equalization. Meanwhile

the government should strengthen the construction of living environment by alleviating the aging crisis

strengthening the flow of regional population and resources

reducing the discharge of industrial pollutants

and improving the air quality.
