| Abstract: | A brief introduction is made on calculation methods for soil and water loss in slope land of mountainous region in Beijing. The problem with calculation method of using runoff plot to estimate regional soil and water loss are detected. Methods of soil loss equation and runoff curve number model are introduced, and specific steps of calculating soil and water loss in slope land are discussed. Using 2013 as the typical year, soil loss and runoff in slope land of mountainous region in Beijing are calculated. It demonstrates that the study result is oractieal and can be referenced by other areas in calculation of soil and water loss. |
