摘　　要：生态基础设施同城市生态安全和健康密切相关。鉴于目前此类问题中量化的不确定性和不完整性,从生态基础设施的概念出发,参考生态城市、园林城市等国际、国内有关指标标准,以大气系统、绿地系统和水文系统为依据,构建了评价指标体系;采用层次分析法和综合指数法建立了评价模型;对三峡库区4个重点城市即重庆主城、宜昌、涪陵、万州等2002—2005年间的生态基础设施品质演化进行了研究。结果表明:4城市生态基础质量都在上升;目前宜昌、涪陵属于较好等级,万州、重庆主城属于一般等级;4城市的生态基础设施质量状况排序由高到低为宜昌>涪陵>万州>重庆主城。通过评价分析,了解了三峡库区4个重点城市的生态基础设施质量状况,为三峡库区城市的规划建设提供了科学依据。Ecological infrastructure is involved with ecological security and health of cities. At present there are so many studies about it. However, quantitative study is much indetermination and imperfection. In this paper in order to ravel out this problem, the evaluation indexes system are established on the basis of air system, greenbelt system and water system from the conception and connotation of ecological infrastructure. They do not only consult inside and outside of Chinese ecological cities and garden cities but also consult with internal and international related index standard. Analytic Hierarchy Process （AHP） and the method of comprehensive index evaluation are applied to establish the evaluation model. Then it studies the quality and evolvement characteristics of ecological infrastructure in the ease of main town of Cbongqing, Yichang, Fulin, Wanzhou the four pivot cities of Three Gorges Reservoir Region from 2002 to 2005. Finally, the paper draws a conclusion by qualitative and quantitative analysis showing that the quality of ecological infrastructure of four cities is in rise. At present, the quality of ecological infrastructure of Yichang and Fulin remains with better grade; Wanzhou and the main town of Chongqing belongs to common grade. The integrated quality eonditins of ecological infrastructure of these four cities follow the sequence （ from high to low） ： Yichang 〉 Fulin 〉 Wanzhou 〉 main town of Chongqing. The quality of ecological infrastructure of four cities is known through evaluation analysis, which has provided a scientific basis for the cities Three Gorges Reservoir Region in programming.
