摘要

The environment of Greater Mekong Sub-region (GMS) was highly payed attention to its economic development. Remote sensing technology was a useful tool for global and regional environment monitor. The fractional vegetation cover (FVC) with 30m spatial resolution for GMS was extracted from the HJ-1/CCD data in this study. The vegetation covers were highly for the entire GMS, and the spatial differences were influenced by vegetation types. Besides, FVC product with high temporal resolution (5 days) and 1km spatial resolution were used to analyze the vegetation damages by typhoon Haiyan from 2ed to 10th Nov., 2013 based on a change detection method. The damage extents of forest by typhoon were much seriously than cropland and grassland for GMS memberships, especially for Vietnam and China (Guangxi). The vegetation damages varied from -50% to 10% in the 300 km suffer areas on the typhoon Haiyan pathway.
