Geological Disasters Risk Assessment in Fushan District in Yantai City Based on AHP Information Method
摘要
Abstract
On the basis of detailed geological disaster investigation and data collection,selecting the slope elevation,slope,engineering geological rock group,distance to fault,distance to river and distance to road as the evaluation factors in the study area,by using Analytic Hierarchy Process,an evaluation system has been set up.Based on ArcGIS,combining with weighted information model,the susceptibility,hazard,vulnerability and risk assessment of geological disasters in Fushan district have been evaluated.The hazard assessment of Fushan district from high to low are 75.89km2,192.7km2 and 668.11km2.The evolution re-sults are verified by ROC curve.The AUC value is 89.9％.It is indicated that the evaluation has good accu-racy.On this basis,the risk has beem evaluated and divided into high,medium and low risk areas,with areas of 12.06km2,222.75km2 and 701.89km2 respectively.This study can provide important references for geological hazard prevention and ecological environment protection in Yantai city.关键词
