Abstract

The Yangtze River is China's longest river and its source region is sensitive to climate variation due to its high elevation. With the influence of global warming, the land cover change can be taken as the joint result of climatic factors. However, during the time when air temperature increased rapidly from 1975 to 2005, the relative importance of global warming to these land cover changes in Qinghai-Tibet Plateau is not well understood. To accurately assess the land cover change during 1975-2005, Landsat images and GIS techniques were used to monitor its distribution in 1975, 1990, and 2005. By overlay analysis, the dynamic patterns of land cover change were observed. The main transition patterns are the higher coverage grassland converted to lower coverage grassland (grassland degradation), grassland converted to swamped land, and the lower coverage grassland converted to sandy land (grassland desertification). The rapid increased air temperature was mostly responsible for the observed land cover change in SRYR.
