摘　　要：本文从压力源-压力流-压力汇的角度构建城市生态环境质量评价指标体系,并对上海闵行区的生态环境质量进行了评价,结果表明闵行区城市生态环境质量的压力源虽然逐年来有所增加,但是其城市生态环境质量的支持力则呈现逐年增大的趋势,故闵行区城市生态环境质量总体向较为理想的趋势在发展。The eco-envirenmental quality in Minhang District of Shanghai was evaluated by the evaluation indicators system of urban eco-envirenmental quality, which have been established on the basis of pressure-source, pressure-flow and the exchange point of pressure-pressure. The evaluation results show a yearly increase of both the pressure source and the supporting capability of the urban eco-environmental quality of Minhang District. However, the increase of the latter is much larger. Overall trend of the urban eco-envirenmental quality of Minhang District is to better in the development.
