摘　　要：针对都江堰虹口乡地质灾害高易发的现状,利用GIS技术与信息量模型相结合的方法,结合专家打分法,开展虹口乡地质灾害风险评价,将其划分为高度、中度、低度和极低度4级风险区地质灾害高低反映了该区域的地质灾害现状,具有较高的准确性,从而说明本文评价方法的有效性,为有效防治地质灾害及后期的灾害监测提供了科学依据。Dujiangyan is high prone to geological disasters. It could better able to master the distribu- tion of geological disasters through the analysis of the geological hazard research of the typical region- al. Taking the Hongkou County of Dujiangyan as the research object, using GIS technology combined with the information model and the expert scoring method to carry out the geological disaster risk assessment in Hongkou district. The geological disaster hazard can be divided into four levels： high, moderate, low and very low. Through the field investigation, the evaluation results can better reflect the geological hazards present situation. The evaluation results has the high accuracy, it can illustrate the validity of the evalua- tion method and provide a scientific basis for the effective prevention and control of geological disasters and disaster monitoring.
