摘要

This paper applied MODIS images to capture LAI data and to evaluate the ecological environmental quality for Yangtze River drainage area. Based on 500mx500m grid data including LAI, topography, precipitation, heat, and other factors, the authors established a comprehensive assessment model of ecological environmental quality. Then we discussed types and spatial distributions of ecological environmental quality index. We found that Yangtze River drainage area had a middle-level ecological environmental quality to some extent, and that spatial difference in ecological quality was strongly impacted by the geographical differences of some natural factors, such as the altitude. Lastly we put forward some policies for ecological conservation in the research area.
