Abstract

"Beijing-1" microsatellite is a new earth observation satellite which China has the right of its operation, management and controlment. It has various technological advantages. This paper explores the feasibility of using "Beijing-1" microsatellite data to estimate vegetation fraction. In this study the Drainage basin of Miyun Reservoir is selected as the study area, and the NDVI method for dimidiate pixel model is chosen as the study method. Through validating with field-investigated data, which is obtained by calculating the vegetation fraction on the digital photography of each land cover type, the average estimated accuracy of vegetation fraction of all land cover types is more than 87.5% in the study region. The result shows that using the "Beijing-1" microsatellite data to estimate and monitor the vegetation fraction at a large scale is feasible.
