Abstract The relationship of thevegetation index and soil erosion was discussed by the spatial overlay statistics of the soil erosion and vegetation data.The vegetation index is gotten from NOAAAVHRR,and classified eight grades.The soil erosion data is by visual inter-preting LANDSAT TM imagery. It is show classified eight that wind soil erosionaccounts for 80.7% of all kind of erosion in vegetation grade 1, congeliturbation erosion and wind erosion dominate in vegetation grade 2 respectively acxeounting for 46.9%and 42.2%，and water erosion dominates from vegetation grade 3 to grade 8. Wester erosion above very heavy dominates in vegetation grade 3.Wind erosion with very heavy dominates in vegetation grade 1.
