Study on Spatial Distribution of Surface Water Resources in Lhasa Based on RS and GIS

Abstract:

Surface water resources study has vital function for Lhasa and whole Tibet. TM images in 2000 and 2010, GIS and landscape ecological theory are applied to analyze the spatial distribution characteristics of Lhasas surface water resources. The results show: there are 6662 patches in 2000 and 6340 patches in 2010, which means there have disappeared 322 patches, while the area have increased 20.95km². The lakes class is the main surface water resources with 41.11% in 2000 and 41.03% in 2010. Tibetan Plateau is very sensitive to global cliamte change, espectially in water resouces. The areas of ice and glaciers, forested swamps, shrub swamps have no change. While other kinds of classs area shows increasing trend, especially rivers area, which increased 12.20 km².
