基于多因素加权灰靶决策模型的滑坡灾害危险性评价
Landslide risk assessment based on multi-index weighted grey target decision model
摘要
Abstract
Starting from the geological environmental conditions within Wanzhou district in Chongqing, the 11 influencing factors were selected, including elevation, slope, precipitation, human engineering activity and so on. Based on grey target decision theory, the weights for screened evaluation influencing factors were determined based on grey association analysis method, and then multi-index weighted grey target model about hazard susceptibility assessment of landslide was established. According to off-target distance, landslide risk classification standards are established, and then the landslide risk rating was divided into high, moderate and low. Based on weighting-grey target decision evaluation model, 6 landslides risks in study area were assessed and analyzed. Each landslide risk was obtained.Compared with evaluation results of adaptive euro-fuzzy inference system, ANN and PSO-BP algorithm, the evaluation results are consistent with actual situation and reasonable. Thus, the model can provide a new idea for landslide hazard evaluation.关键词
