GIS-based USLE(Universal soil loss equation)was used to predict the spatial pattern of soil erosion in the black earth region of China.The primary results indicated that soil loss was 0~60t/(hm2 a)in the study area with the area of zero erosion
slight erosion
moderate erosion
intensity erosion
accounting for 28.7%
56.2%
18.6% and 0.1%respectively.The little soil loss occurred with 0~5t/(hm2 a)at the top of slope
big soil loss of 3~15t/(hm2 a)on the slope shoulder and back slope.GIS-based USLE can efficiently predicted soil loss distribution on top of the slope
slope shoulder and back slope other than the distribution of soil deposit and gullies at the foot of the slope.
