Abstract—Dynamic changes of the wetland in Qinghai-Tibet analysis can provide certain theoretical basis for the protection
Plateau were analyzed by using images of the TM (Thematic of wetland and water resources etc.
Mapper) in 1990, the ETM+ (Enhanced Thematic Mapper Plus)
in 2000 and the CBERS (China and Brazil Earth Resource
II. STUDY AREA
Satellite) in 2006 as the main data source in this paper. And
through puter interactive visual interpretation the Qinghai-Tibet Plateau, the study area, situates at the
wetland data of different periods in Qinghai-Tibet Plateau was southwest part of China, between the longitudes 73°20′–
obtained. The results show that the existing wetland area is about 104°20′ E and the latitudes 26°10′–39°30′ N. It covers a total
km2 in Qinghai-Tibet Plateau. The total area of the area aro
