摘　　要：流域生态环境质量对于流域可持续发展具有重要影响．借助RS和GIS技术获取土地利用数据，并以此为评价主要基础数据，通过生物丰度指数、植被覆盖指数、水网密度指数、水土保持指数和污染负荷潜力指数五个评价因子建立综合指数评价模型，对小清河流域1984-2010年生态环境质量进行分析评价．结果表明流域生态环境质量属于“一般”级别，生态环境总体有所改善，但仍需要继续加强流域生态环境保护力度，以促进流域可持续发展．The ecological environment quality plays an important role in basin sustainable development. The paper used the land use data as evaluation data, which was acquired through RS and GIS techniques, established comprehensive index evaluation model with five evaluation factors of species richness index, vegetation cover index, drainage density index, soil and water conservation index and pollutant burden poteneial index, and then evaluated the ecological environment quality of Xiaoqing River ecological environment quality belonged to the level basin during 1984 -2010. The result indicated that the basin of ＇moderate＇ , and ecological environment quality had been improved during 1984 -2010. The protection measures of basin ecological environment should be strengthen so as to motivate the basin sustainable develooment.
