Abstract

With MODIS-EVI data, Dimidiate Pixel Model is applied in analysis of the vegetation coverage change at Ertan reservaoir area in south China from year 2000 to 2009. Findings include: a) the study area mainly focuses on middle and high level vegetation; b) the overall vegetation coverage shows an increasing trend during last decade, while in some small parts of the area vegetation degradation exists.

基于遥感的二滩库区植被覆盖度估算及动态变化分析
利用MODIS-EVI数据,应用二次像元模型对2000 - 2009年中国南方二滩库区植被覆盖度变化进行了分析。研究结果表明:a)研究区以中高层植被为主;B)近10年植被覆盖度总体呈增加趋势,但局部地区存在植被退化。
