摘　　要：建设长江流域绿色发展示范带是美丽中国建设的重大任务,开展城市绿色发展评估和障碍影响识别有助于推动长江流域绿色发展。构建了以水为纽带、体现“三水”统筹的长江流域城市绿色发展指标体系,基于CRITIC-熵权、TOPSIS、障碍度模型和系统聚类等综合评价方法,对流域内63个重点城市2012—2021年的绿色发展和障碍影响进行评估。结果表明:(1)共抓大保护以来长江流域城市绿色发展进程明显加快;(2)经济规模、生产率、环境效率对城市绿色发展的阻碍明显减小,产业结构重化工化、农业面源污染的阻碍更加突显,多数城市绿色发展都面临水资源开发程度高和经济社会用水效率低的障碍;(3)生态阻力型城市应重点加强水生态环境安全管理,降低资源开发强度,执行更严格的管控制度;经济阻力型城市应重点发展零污染产业,建立健全生态产品价值实现机制;效率阻力型城市应强化水资源刚性约束,推动工农业生态循环发展,大幅提高资源环境效率;生态-经济阻力型城市应率先推动涉水产业绿色改造和优化升级,提升市场竞争优势,同时加强涉水产业环境风险管理;混合阻力型城市应重点依靠创新驱动推动产业转型升级和资源环境效率提升,同时统筹好“三水”关系。As part of the construction of One Beautiful China,it is imperative to establish a demonstration belt for green development in the Yangtze River Basin.Identifying obstacles to urban green development and assessing the process can assist in promoting a green and high-quality development of the Yangtze River Basin.Currently available green development evaluation studies are unable to reflect the unique characteristics of the cities in the watershed,which are linked by water,and the requirements of“Three Waters”coordination(i.e.Water resources,Water environment,and Water ecology)in the new era of urbanization.Furthermore,identification of obstacles to green development and the improvement paths has not been sufficiently targeted.In existing studies,the entropy weighting method does not take into account the correlation between multidimensional indicators of green development.By addressing the shortcomings of existing research,this article developed a water-linked urban green development indicator system that can reflect the“Three Waters”coordination for the Yangtze River Basin,and adopted comprehensive evaluation methods including CRITIC-entropy,TOPSIS,obstacle degree model,and systematic clustering to assess the green development process and the impact of obstacles in 63 key cities in the basin from 2012 to 2021.In addition,the article proposed the differentiated approaches to promoting green development.The results show that:(1)The green development process of cities in the Yangtze River Basin has been significantly accelerated since the implementation of co-protection policy in 2016.(2)Although the obstacles to green development of cities have been significantly reduced due to economic scale,productivity,and environmental efficiency,heavy chemicalization of the industrial structure and agricultural non-point source pollution have become more prominent.Additionally,most cities faced barriers to green development due to high levels of water exploitation and inefficient economic and social water use.(3)Based
