基于综合防治体系抗灾能力的泥石流沟风险评价
Risk Assessment of a Debris Flow Gully Based on Anti-disaster Ability of Comprehensive Prevention and Control System
摘要
Abstract
With the gradual advance of the comprehensive prevention and control system of geological hazards,the disaster prevention and mitigation awareness of the mountainous area masses has been greatly improved.On the basis of the traditional disaster inherent properties and inherent attributes of hazard bodies,this paper attempts to introduce the anti-disaster capability of the comprehensive prevention and control system into the assessment model and apply it to the risk assessment of a single debris flow.The assessment results show that the study area belongs to the high risk,moderate vulnerability,low anti-disaster ability and medium risk areas,the risk of expected results is lower than that of the traditional model of debris flow risk assessment results.The reason is that,with the gradual establishment of a comprehensive prevention and control system in our country,there are risks of geological hazards where there are varying degrees of anti-risk ability,this is the force and counterforce,disaster prevention should not only emphasize on the magnitude of the force and ignore the influence of counterforce,otherwise it will exaggerate the geological hazards negative energy and weaken the human positive energy of response to disaster,excessive disaster prevention will lead to the waste of resources.Reasonable risk assessment of geological hazards is an inevitable requirement of scientific and technological achievements into productive forces.关键词
