- Abstract:
-
The physical mechanism of soil erosion is so complicated that it is difficult to be described by the mathematical mode. According to the characteristic of vagueness, randomness and nonlinear of soil erosion process, the RBF neural network theory and method are applied to soil erosion prediction. With Xingmu small watershed as the research case, the application of RBF neural network method was adopted to construct soil erosion prediction model, and flood season rainfall, runoff coefficient, soil capacity, organic matter content and porosity and so on were used as input layer variables, and yearly soil erosion modulus were used as the output layer variable. Through the simulation training and the forecast, results obtained through RBF neural network were precise, RBF neural network could be used as soil erosion prediction model, compared with the traditional BP neural network, RBF neural network could give the higher accuracy prediction results. RBF neural network model shifts soil erosion prediction problem into the impact factor and erosion modulus nonlinear problem, the model of the simulation and forecast provides a new way to complex law of soil erosion research.
