APPLICATION BP ARTIFICIAL NEURAL NETWORK IN HAZARD PREDICT OF LANDSLIDE

Because of complexity of the regional landslide hazard assessment, the relation between known variants and unknown ones is very strong nonlinear. The BP neural network has high non-linear mapping capacity, and a good result can be obtained with BP neural network to analyze the regional landslide hazard. The paper creates BP neural network by use of Matlab neural network toolbox,combining regional landslide hazard assessment, to examine and predict hazard of regional landslide.
