摘　　要：以湖北宜昌三峡翻坝运输江南公路沿线环境为研究对象,使用数据来源于卫星遥感图片,采用GPS、RS和G IS相结合的空间信息技术完成植被类型图、土地利用图。依照《生态环境状况评价技术规范(试行)》有关要求,计算出区域生态环境各项指数:生物丰度指数98.29、植被覆盖指数88.28、水网密度指数72.40、土地退化指数19.06、环境质量指数为93.53、生态环境状况指数74.55,评价区生态环境质量较好,生物多样性较丰富。Based on the images from satellite remote sensing, the environment in the area along Jiangnan Highway in Fanba, Sanxia in Hubei Province was studied to get distribution maps of vegetation pattern and maps concerning the situation of land utilization, by combining the technology of space information, i.e. , GPS, RS and GIS. According to the requests of the Technical Specification for Assessment of Eco-environment, different indices for local t were calculated including biological abundance （98.29）, vegetation coverage （88.28）, water-network density （ 14. 17 ）, land retrogression （ 19. 06）, environmental quality （93.53） and eco-enviromnental situation （74. 55） . It concluded that the environmental quality of the assessed area was quite good and rich in biodiversity.
