Research on the Dynamic Change of Land Cover in Alpine Meadow Ecosystem

YU Long et al(Northwest Plateau Institute of Biology,the Chinese Academy of Sciences,Xining,Qinghai 810001)  
The authors monitored the dynamic changes of land cover in Haibei Research Station of Alpine Meadow Ecosystem with 1987 and 2000 TM datum based on the RS and GIS technology.The results showed that prominent change had taken place in the past 14 years.The land used for urban and rural residence was increasing rapidly,and the grassland was reduced and increasingly changed into unused land.It was also shown that wetland,the forest land and the comprehensive land-using index hws decreasing obviously,indicating that the desertification became stronger.
