| Abstract: | In the context that the Ministry of Water Resources has proposed the implementation of regional soil and water conservation assessment for various types of development zones, we analyzed the methods and technical points of soil erosion volume prediction. Taking Qing’an Development Zone as an example, the analysis of soil erosion prediction and soil balance estimation of China’s northeastern black soil area could provide reference for soil erosion calculation and soil and water conservation assessment in similar areas. Through the calculation and analysis, two conclusions are obtained: (1) considering the most unfavorable conditions, the largest amount of new soil loss is from industrial land in the prediction area; (2) for the planning and construction areas and the areas under construction, the plan of soil and water conservation for completed typical project could be used for analogous calculation of the regional soil excavation and filling methods. |
