Estimation and Dynamic Changes Analysis of Vegetation Coverage in the Ertan Reservoir Area Based on Remote Sensing

摘要

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.
