摘　　要：生态系统健康评价是生态学研究的热点之一.本研究以长江经济带的40个城市为研究对象,从系统活力、组织力、恢复力、生态服务功能和人群健康状况等5个维度构建城市生态系统健康评价模型,对其2006—2018年生态系统健康状况进行综合分析.研究表明从整体上看,2006—2018年长江经济带城市生态健康状况向健康方向发展,但不同城市间生态系统健康状况存在明显差异,还有一些城市生态系统处于亚健康或病态水平如恩施、宜宾、泸州与鄂州等.这为政府采取差异化的城市发展战略,进而实现长江经济带城市经济与生态环境的协调、可持续发展.Ecosystem health assessment is one of the hotspots in ecological research.This study takes 40 cities along the Yangtze River economic belt as the research object,five indices were selected to build urban ecosystem health evaluation index system,including system vitality,organization,resilience,ecological service function and population health status,and using the method of fuzzy mathematics evaluation on a comprehensive analysis of ecosystem health.The results show that the overall urban ecological health of the Yangtze River economic belt developed towards a healthy direction from 2006-2018.However,there are significant differences in the health status of the urban ecological systems along the Yangtze River economic belt,and some urban ecological systems are at a sub-healthy or pathological level,such as En'shi,Yibin,Luzhou and E'zhou.This result provides a theoretical basis for the government to adopt the strategy of differentiated urban development and realize the coordinated development of urban economy and ecological environment in the Yangtze River economic belt.
