Paper Abstract

Vegetation coverage and its changes are one of the hottest research branches in regional ecological environment change. An important research content of vegetation coverage is vegetation fraction. Hydropower exploitation cascade in a river basin inevitably makes vegetation fraction change. In this paper, the sub-pixel decomposition model and NDVI have been applied to quantitatively estimate vegetation fraction change of Qingjiang River downstream based on remotely sensed data. The results show that the overall vegetation environment has been greatly improved and the hydropower cascade development has a greater influence on vegetation fraction change in Qingjiang River basin form 1987 to 2004.
