| 摘 要： | 华蓥山地区地质灾害分布广、危及面积大且区内降雨量丰富,建立相应的区域预警系统,可以减小灾害带来的损失。选择影响地质灾害易发性的评价指标并将其量化,建立Logistic回归模型,计算区域内已划分各单元格地质灾害发生的概率值,同时利用Logistic回归模型对地区实时监测降雨信息进行统计分析,计算降雨量引发地质灾害的概率值。依托MapGIS平台分析生成研究区地质灾害危险性区划图、降雨量危险性分级图和预警等级图,并进行预警信息的发布。

Research on Regional Warning System of Geological Disasters of Huayingshan Based on Monitoring Rainfall |

| Abstract: | Huayingshan geology disaster wide distribution,endanger the area is large.Setting up a corresponding regional early warning system can reduce the loss of the disasters.We chose the geological disaster which was prone to influence the evaluation index,and established Logistic regression model,calculated probability values that area had divided each cell of geological disaster.Using Logistic regression model of real-time monitoring area rainfall information to statistical analysis,and calculated probability value of geological disaster caused rainfall.Based on analysis of the study area MapGIS platform,we generated geohazard danger zoning and rainfall classification figure and early warning risk level figure,and early warning information release. |
