摘　　要：以上海市闵行区为例,从社会、经济、自然等方面构建了一套城市生态环境质量的指标体系,结合专家咨询和层次分析法,确定了各指标的权重体系.结合反映城市生态环境质量的指标体系和权重,采用基于矢量的空间叠加方法,对表征研究区域的城市生态环境质量的单因子和多因子的空间分异规律及其成因进行了探讨,为研究区域的城市生态化建设提供了决策支持.Based on a case study of Minhang district of Shanghai, a city ecological environment quality index system is established, which covers the society, economy and the nature and so on. The weight of indicators is decided according to experts＇ advice and the method of analytic hierarchy process. With the vector-based spatial overlapping method, an investigation is made into the spatial variation and its causes for eco-environment single-factor and multi-factor. The study result offers a decision support for city ecological development.
