Abstract:: For the hot issues of the relationship between landuse and soil erosion changes, using the multisource remote sensing image data as data sources, based on the analysis of landuse changes and the dynamic changes of soil erosion in Chengguan District of Lhasa, this article discussed the extraction method of landuse and soil erosion changes information on the basis of remote sensing data such as MSS/TM/ETM+/CBERS, etc. And using GIS spatial analysis techniques, revealed the coupling relations between the changes of landuse and soil erosion. Studies have shown that grassland is the main landuse type in Chengguan District of Lhasa, the main factor of changes of soil erosion intensity is the grassland changes, therefore, the role of grassland in preventing soil erosion can not be ignored. This study provides a reference for monitoring and evaluation land degradation of different-scale, and a scientific basis for the regional planning and implementation of sustainable use.
