Abstract	The indulge persecution of sandstorm had attracted great attention of many countries around the world. Chinese government and the Chinese academy of science going with some other countries have devoted a large amount of vigor to study the crucial environment problem. Following the study development, an international cooperation organization has been established to clarify the produce mechanism, transfer process and the environment impact of sandstorm. The organization includes many researchers come form USA, Japan, Korea, and so on. The main source areas of sandstorm all located in the arid and semi-arid regions where there have immeasurable bound, hard natural condition and bad traffic condition. The case study region of Beijing surrounding area includes 61 counties that belong to three provinces and autonomous regions, which is one of the sand sources of Asia sandstorm. In order to fully understand of the sandstorm form and development, we analyzed the land use degradation of Beijing surrounding area during the latest ten years. 71 scenes Landsat TM/ETM, 611 scenes DRG and DEM data had been processed in our study. This paper made a detail describe of using Landsat image data and high resolution DEM data to construe the soil erosion and vegetation degenerate. The study has extracted data set of land use information and the temporal change of land use degradation from TM/ETM image data in Beijing surrounding area. The time span is from 1990 to 2000. Three indexes i.e., the assessment index of land using degradation, construction relative index and compare relative index of land using degradation had been used to analyze the dynamic land use degradation changing in research region.
