摘　　要：三峡库区是我国水土流失比较严重的地区之一 ,面临着生物多样性下降、生态系统功能降低、农业非点源污染加剧、岸边污染带扩大、水质恶化等一系列的环境问题。本文在建立生态环境综合评价指标体系的基础上 ,根据三峡库区不同地区生态环境问题的相似性和差异性 ,进行了聚类分析。依据聚类分析结果可以将该区Besides serious soil erosion,the Three Gorge Region is faced with a series of environmental issues,such as diminishing biodiversity,degrading functions of the ecosystem,aggravating agricultural non point source pollution,expanding polluted zone ashore and deteriorating water quality.Based on a comprehensive eco environment evaluation index system,and similarity and dissimilarity of the eco environmental issues in different areas of the Three Gorge Region,clustering analysis was made.Results showed that the 19 counties(cities)in the region could be sorted into 7 groups of areas.
