摘要
滑坡危险性评价对滑坡的防灾减灾工作具有重要意义。基于信息熵理论建立了滑坡危险性评价模型,同时综合考虑影响滑坡演变的各种因素,在GIS下对四川省青川县滑坡的监测数据进行了分析和处理,获取了该研究区滑坡危险性区划结果,并将该区不稳定斜坡作为未来可能发生的滑坡进行验证,结果表明其评价结果基本符合实际情况。该评价模型可用于滑坡的危险性评价。
Landslide hazard assessment is very important for the landslide disaster mitigation and prevention.This paper establishes the landslide hazard assessment model based on comentropy theory and,by the comprehensive consideration of various factors that influence the landslide,obtains the landslide zonation with the spatial overlay function of geographic information system（GIS）.For the assessment of landslide hazards in Qingchuan County,Sichuan Province,the feasibility of this model is verified by taking the unstable slopes in the area as the possible future landslides.The results indicate that assessing results of the model are basically in accord with the reality,so this model can be used for assessing the risk of landslides.
