摘　　要：从县域生态系统健康的概念和内涵出发,以自然生态子系统、社会生态子系统和经济生态子系统构建城市生态系统健康评价指标体系,采用层次分析法和模糊数学法构建评价模型,并以重庆三峡库区生态经济区19个区县为研究对象,对其县域生态系统健康状况进行了实例研究。结果表明:奉节、巫山、巫溪和城口的生态系统健康属于"不健康"等级;万州、忠县、丰都、武隆、石柱、垫江、梁平、开县和云阳处于"亚健康"等级;秀山、酉阳、黔江和彭水处于健康等级。通过分析,明确了生态经济区的生态系统健康状况,为生态经济区的可持续发展提供了参考和借鉴意义。The index system for urban ecosystem health assessment was established in terms of natural ecosystem, social ecosystem and economic ecosystem on the basis of the conception and connotation of urban ecosystem health. Analytic Hierarchy Process （AHP） and Fuzzy Mathematics were applied to establish the assessment model. Nine- teen districts and counties in the Three-Gorges Eco-economic Region in Chongqing were taken as a case study. Re- sults reveal that the ecosystems in Fengjie, Wushan, Wuxi, and Chengkou were assessed to be unhealthy. The eco- systems in Wanzhou, Zhongxian, Fengdu, Wulong, Shizhu, Dianjiang, Liangping, Kaixian, and Yunyan were sub-healthy, and those in Xiushan, Youyang, Qianjiang, and Pengshui belong to healthy grade. The countywide e- cosystem health in the region was obtained, which provides scientific basis for its sustainable development.
