Susceptibility evaluation of landslide in the high-tech region of Zhenjiang based on weighted information
The key to the accurate evaluation of geological hazard susceptibility is to select the influencing factors and factor classifi-cation reasonably.According to the actual situation of the study area,seven index factors have been selected to build the landslide in-fluence factor index system.The continuous index factors of evaluation have been optimized and graded with the landslide disaster pro-portion and the abrupt point of information curve under each factor condition.Based on the grading and the ArcGIS platform,the infor-mation model weighted by analytic hierarchy process was used to evaluate susceptibility of landslide in the high-tech region of Zhen-jiang.The study area was divided into high,medium and low risk area,which corresponded well with the distribution of existing land-slides.This evaluation method can provide reference for the evaluation and control planning of landslide geological hazards in low moun-tain and hilly areas.
