Abstract:In order to calculate the black soil erosion thickness by slope erosion under rainfall. The mathematical model which can forecast the deforming of the slope was builded. It consists of the equation of the slope flow continuous equation, slope flow water kinematical equation, slope soil erosion equation, slope deformed equation. This article calculated the black soil erosion thickness by slope erosion under rainfall. The result can predict the time limit of which the black soil erosion thickness can be eroded, and provides scientific basis for preventing loss of water and erosion of soil, reducing geological disasters, using cultivated lands reasonably and protecting ecological environment.
Keywords:black soil  erosion  deforming of the slope  numerical calculation
