基于信息量模型的地质灾害风险性评价
Risk assessment of geological hazards based on information model:Taking Heyun Town of Qingyuan City as an example
摘要
Abstract
Heyun Town is a mountainous and hilly area with complicated geological environment conditions and high risks for geological disasters.In order to meet the needs of geological disaster monitoring and early warning,disaster prevention and mitigation and rural construction planning,and effectively protect the safety of people's lives and property,it is urgent to carry out a more systematic,detailed and refined investigation work in Heyun Town.In this paper,the existing hidden danger points of geological disasters,historical disaster data and field investigation data are taken as the basic data for evaluation,and the information model method is adopted,with landform(elevation,slope,slope shape,slope direction,topographic relief),geological background(rock and soil type,geological structure,soil layer thickness)and surface coverage(vegetation coverage and land use type)as indicators to carry out geological disaster risk evaluation.The whole area of Heyun Town is divided into high,medium and low risk areas of geological disasters.关键词
