Study on Calculation Methods of Rainfall Eroding Force in the Main Urban Area of Chongqing Municipality

The soil and water loss produced by rainfall and caused by excavated and filled spoil of the city and sloped land water erosion are the focal points to be studied on soil and water conservation due to the fast progress of urbanization and industrialization of Chongqing Municipality. Comparing with other models, the calculation results are very close to that of the established R value calculating model of rainfall eroding force. It has shown better operation performance. It can meet the applied requirements of predicting short-period soil and water loss of the key city area and working out a soil and water conservation plan of the municipality. The paper also introduces the characteristics of rainfall eroding force of the key area of Chongqing.
