Paper Abstract

It's well known that soil erosion is a complicated phenomenon. It's hard to express it with a uniform equation, however BP artificial neural network has great advantages of solving non-linear problems, so it can use BP artificial neural network to research on soil erosion quantitatively. In this research it lays out experiment in the east and west of Liaoning province. It measures 4 factors which mainly influence soil erosion except quantity of soil erosion. They are rainfall erosivity, slop, soil water content before rainfall and crop coverage. These data are composed of 85 samples in total. This paper builds double-layer BP artificial neural network for east region and west region respectively. It uses some samples to train BP artificial neural network and others to verify it. Research results show that judging from the errors these two BP artificial neural networks can be applied to research on soil erosion quantitatively. Simulative results can be used to confirm the rank of soil erosion. Comparing with the results of multi-factor orthogonal regression analysis using BP artificial neural network is much more approaching the real value. Besides it discusses the problems on BP artificial neural network application.
