[Objective] Quantitative monitoring of soil and water loss in representative districts of soil and water loss in key control and prevention areas was conducted to grasp the relative conditions of soil and water loss, and to provide technical methods and theoretical support for dynamic monitoring of soil erosion.[Methods] High-resolution remote sensing images, DEM and rainfall data in Tongshan District of Xuzhou City and Ganyu District of Lianyungang City in Jiangsu Province were collected. And Chinese soil erosion equation (CSLE) was used as the basic algorithm to calculate the potential losses of soil and water.[Results] The area of soil erosion in Tongshan district was 1 917.82 km², mild loss area and above was 175.76 km², accounting for 9.16% of the total loss area. The area of soil erosion in Ganyu district was 1 511.2 km², mild loss area and above is 131.95 km², accounting for 8.73% of the total loss area.[Conclusion] The model parameters of the research are real and objective, and are not interfered by human factors. It is suitable for multi-period and/or large-scale dynamic monitoring of soil erosion, and will provide an efficient and feasible method for the dynamic monitoring of soil erosion in Jiangsu Province in the future.
