摘 要:长江经济带生态文明建设水平的高低关系到长江流域绿色协调发展能力,深刻影响我国生态安全格局。从生态经济、生态环境、生态社会3个层面构建评价指标体系,使用改进TOPSIS方法模型测算长江经济带生态文明建设水平,利用地理加权回归模型(GWR)分析其影响因子。研究结果表明:(1)在2011—2020年,长江经济带生态文明建设水平整体上呈上升趋势,由东向西沿轴线逐步扩散。(2)各子系统建设水平异质性特征显著,生态经济建设水平东部高于西部,以长江下游地区和省会城市为核心向周围辐射发展;生态环境水平在各省会及其周边城市增长较快,而工业发展型城市有不同程度的降低。生态社会水平高值区集中分布在江浙沪地区,低值区分散分布于中上游各省会城市。(3)地形、常住人口城镇化水平、第三产业占比、恩格尔系数、科技财政支出占比均正向影响了研究区生态文明建设水平,每万人在校大学生数对生态文明建设水平呈弱负相关。The level of ecological civilization construction in the Yangtze River Economic Belt is related to the green and coordinated development capacity of the Yangtze River Basin,which profoundly affects the ecological security pattern of China.This paper constructed an evaluation index system from three levels(i.e.,ecological economy,ecological environment and ecological society)to measure the level of ecological civilization construction in the Yangtze River Economic Belt using an improved TOPSIS method model,and analyzed its influence factors using a geographically weighted regression model(GWR).Main findings of the study are as follows.(1)From 2011 to 2020,the ecological civilization construction level of the Yangtze River Economic Belt shows an overall upward trend,gradually spreading from east to west along the axis.(2)The construction level of each subsystem is characterized by significant heterogeneity,with the ecological economy construction level being higher in the east than that in the west,with the lower reaches of the Yangtze River and the provincial capital cities as cores radiating around.The ecological environment level grows faster in the provincial capitals and their surrounding cities,while the industrial development cities have different degrees of decrease.The high value areas of eco-social level are concentrated in Jiangsu,Zhejiang and Shanghai,while the low value areas are scattered in the capital cities of the middle and upper reaches of the provinces.(3)Topography,urbanization level of resident population,share of tertiary industry,Engel coefficient,and share of financial expenditure on science and technology all positively influence the level of ecological civilization construction in the studied areas,and the number of college students per 10,000 people is weakly negatively correlated with the level of ecological civilization construction.
