Abstract: With non intercropping as a control,milkvetch, mixture of ryegrass and milkvetch and ryegrass were respectively intercropped with young citrus trees and the relationships of underlying soil surface with rainfall and soil erosion were analyzed and simulated. The amount of eroded soil from intercropped plots was greatly reduced,being only 14.7% as compared with control on the average.The amount of eroded soil is decreased exponentially with increasing order of rain course and increasing coverage of soil surface.

Key words: Underlying surface, Intercropping in young citrus plantation, Soil erosion, Simulation study, alpine meadow, grazing intensity, community characteristics, soil factor
