| Abstract: | Landslide hazard is a complex system of holism, dynamic, open and random characteristics; and the artificial neural network model is a nonlinear dynamic system, which is fit for regional landslide hazard risk prediction. The BP model for the zonation prediction of the landslide hazard risk is established. Applying BP model and GIS technology, the landslide hazard comprehensive prediction of New Badong County is carried out. Based on hazard evaluating and vulnerability estimating, the landslide risk after the completion of Three Gorges Reservoir is predicted in study area. The applicability of BP model for landslide hazard risk prediction is proved. At the same time, the existing questions and the possible solving ways are put forward. |
