The 3S techniques are the integration of Global Positions System and Remote Sensing and Geographical Informatin System, and are efficient for the study of soil erosion. 3s techniques can quickly monitor the changing process of the soil erosion, the result can supply evidence for the government's land protection decisions. This paper introduces the standard of the soil erosion grading, then studies the method of assessing the vegetation covering ratio, slopes and land utilizing in TM image:vegetation covering ratio is extracted by TM432 and NDVI,the slopes data come from DEM, infield distribution data is obtained from land utilizing distribution map. We analyse soil erosion status and its change in the northeast of Hubei province with low hill and hill land through analyzing the vegetation covering ratio, slopes and land utilizing synthetic:in the sustain ARC/INFO software. This paper analyze the intensity and distribution of soil erosion in the Northeast of Hubei Province by 2000's TM image, and analyze its change by comparing the data between 2000 and 1995.
