Abstract  

The study area of this paper is Qinghai Lake, the largest salt lake in China, which lies in the northwest of Qinghai province. The data derived from TM image in 1986 and 2000. Based on Remote Sensing, GIS and Mathematical Statistics, we analyze quantity and spatial construction changes of the landuse types. We also discuss the influence of the land use changes on the Qinghai Lake' s environment. The result shows that the farmland, water area and residential area all increase by 5 930.82 hm2, 2 218.75 hm2 and 382.69 hm2respectively. But the forest land, grassland and un-used land decreased by 7 542.64 hm2,894.34 hm2and 95.28 hm2respectively. In the decreasing part of the grassland, 6 266.56 hm2grassland area changed into cultivated land and 601.40 hm2grassland area changed into sand.
