外文摘要：The Zoige Wetland lies in the northeastern Qinghai-Tibet plateau, a region that is highly sensitive to global environment change because of its high elevation and cold environment; thus, it's a hotspot for land use and cover change (LUCC) research. In this study, we used Landsat images to monitor LUCC in this region using GIS techniques, as well as topographic, vegetation, and soil maps combined with field investigations. LUCC processes from 1975 to 2005 in the Zoige Wetland were gained through visual interpretation of multi-temporal remote-sensing images at a scale of 1:100,000. The monitoring result shows that the region's eco-environment degraded steadily in the 30 years.
