摘要:
利用1988年TM图像和2003年ETM+图像，基于植被指数（NDVI），反演二滩库区米易县植被覆盖度，并借助GIS技术，对米易县1988-2003年植被覆盖动态变化进行分析。研究表明，研究区植被覆盖度变化与人类活动、自然因素有密切关系。其中二滩水库的蓄水作用对研究区生态环境变化产生重大影响，对植被覆盖度变化有重要意义。基于遥感技术进行库区植被覆盖度动态变化分析的研究思路和方法，将为水电开发生态环境影响的回顾评价提供重要的参考和借鉴。
Abstract:
Using TM image in 1988 and ETM+ image in 2003 and based on NDVI,this article analyzes dynamic changes about vegetation cover of Miyi county from 1988 to 2003 with the help of GIS.The result shows that there is close relationship between changes about vegetation cover and human activities and natural factors.Storing water in Ertan reservoir has significant influence on ecological environment changes and vegetation cover changes.The method that analyzes dynamic changes about vegetation cover in reservoir area can provides important reference and model for review appraisal on ecological environment influence which will be brought about by water and electricity development.
