摘    要:在遥感和地理信息系统软件支持下,提取并分析了参与研究区生态环境质量综合评价的6个参评因子:海拔高程、土地覆盖类型、植被指数、植被净初级生产力、年均温度、年降水量诸自然环境因子的现状。通过熵权法确定6个参评因子的权重值,建立研究区自然生态环境质量综合指标评价模型,并利用该模型对南水北调西线一期工程区的自然环境进行定量分析。

关 键 词:遥感  地理信息系统  熵权法  生态环境综合评价

Abstract:On the support of remote sensing and geogrphic information system software, six factors inpacting the eco-environmental synthetic evaluation of the studying area were extracted and analyzed, such as elevation, land-cover type, vegetation index, vegetation net primary productivity, annual average temperature, annual precipitation and other factors of the environment status. The eco-environmental comprehensive evaluation of the studying area was carded out based on the comprehensive eveluation model. The results showed that the quility of the eco-environment in the western route of the south-north water transfer project was good in general,and in the space distribution, the quility of the eco-environment in the southeast was better than in the northwest, which was in agreement with the investjigation results.
Keywords:Remote sensing  GIS  Entropy method  Comprehensive evaluation of eco-environment
