Landslide Susceptibility Evaluation of Haidong Urban Area Considering Time Series InSAR
摘要
Abstract
Aiming at the misclassification results of false negative and false positive errors in the traditional landslide susceptibility evaluation model,we proposed an information-logistic regression(IV-LR)landslide susceptibility evaluation method considering time series InSAR.Taking Haidong urban area for example,we used SBAS-InSAR to obtain the annual average deformation velocity in the study area,and taking deformation velocity and tradition evaluation factor as the input variable of IV-LR model,generated a new landslide susceptibility map.The results show that the deformation velocity factor has an obviously influence on the IV-LR model.Compared with the original landslide sensitivity mapping that only considered tradition evaluation factor,the proportions of high and extremely high sensitive areas in the new landslide sensitivity mapping increase by 0.18%and 1.7%,respectively.The AUC increases from 0.901 to 0.925.The impact of misclassification results is effectively reduced,and the prediction accuracy is higher,which can provide a more reliable reference for the landslide prevention and control work in Haidong urban area.关键词
