Geological Hazard Susceptibility Study Based on Information Value and Information Value-Logistic Regression Model Integration Method—A Case Study of Majian Town,Zhuji City
摘要
Abstract
For the study of the reliability of two methods,the Information Value Model Comprehensive Method and the Information Value-Logistic Regression Model Comprehensive Method,in the assessment of geological hazard susceptibility in rural towns,Majian Town in Zhuji City,north Zhejiang Province,was selected as the research subject.By applying quantitative mathematical and statistical principles,nine influencing factors were selected:slope,aspect,height difference,slope type,thickness of the covering layer,lithology and litho-structural characteristics,slope structure,distance to the fault,and slope height.The Information Value Model and the Information Value-Logistic Regression Model were used in conjunction with the assessment of the susceptibility to valley debris flow,to comprehensively assess the designated slope units.The results showed that both methods were able to assess the susceptibility of geological hazards relatively objectively and accurately,with AUC values of 0.901 and 0.899,respectively.This indicates that the Information Value Model Comprehensive Method performed slightly better in terms of rationality and accuracy.This study provides important technical support for the investigation and assessment of geological hazard risks in the related rural towns.关键词
