基于逻辑回归模型的山区城镇地质灾害风险评价方法
Risk assessment method of geological hazards in mountain towns based on logistic regression model
摘要
Abstract
Taking Xuanwo Town,Hanyin County as the demonstration zone and using slopes as the basic unit,this paper carries out large-scale and refined surveys of the geological environment.Logistic regression is applied to analysis the various hazard factor weights,establish a comprehensive index method model,and evaluate the susceptibility of geological hazards.Hazard risk of slope unit is assessed by taking the daily rainfall of 80mm as the rainstorm condition.Rick vulnerability is evaluated according to the threatened personnel and property targets.The risk level of slope unit under rainstorm condition is analyzed base on the geological hazard risk index and the vulnerability index of hazard-affected,and the geological hazard risk zoning is determined according to the principle of"same within the risk region and different between administrative regions",and the administrative villages as the boundary.The evaluation results are verified to be reliable using ROC curve test and through comparison with previous investigation results,and field reverification.关键词
