Abstract We do the cross radiation correction with the RS data of BJ-1 and TM data at the corresponding period,and calculate the vegetation coverage degree in the area of Da Hingganling Mts,establish the soil erosion spatial information database of this area.Based on the RUSLE theoretically,with the ground investigation,we established soil erosion repository,construct the soil erosion monitoring method coupling the spatial information and repository,grading the intensity of soil erosion in Da Hingganling Mts.The tested results indicated that the method we introduced has a better reliability,and BJ-1 can meet the demand of dynamic soil erosion monitoring.The obtained calibration parameters of BJ-1 has a certain reference value.
