摘　　要：黄山区作为安徽省地质灾害频发区域之一,一直以来针对其地质灾害发育规律的研究较为缺乏。经过现场野外调查分析、结合GIS空间分析技术,基于“信息量模型法”从坡度、地形起伏度、坡体结构、断层缓冲层距离和工程地质岩组5个维度对其地质灾害发育规律进行探索,全面地对黄山区的地质灾害易发性进行综合评价。研究不仅为黄山区地质灾害的防灾减灾提供了科学依据,也为类似地形和地质条件区域的地质灾害研究提供了参考;同时,研究结果对于指导当地地质灾害监测预警、风险管理和应急响应具有重要意义。As a region prone to geological hazards in Anhui Province,Huangshan District has long lacked systematic research on the developmental patterns of such hazards.This study integrates field investigations with GIS spatial analysis and employs the Information Value Model(IVM)to explore hazard mechanisms across five dimensions:slope gradient,topographic relief,slope structure,distance to fault buffer zones,and engineering geological lithology.A comprehensive evaluation of geological hazard susceptibility in Huangshan District was conducted.The results not only provide a scientific basis for hazard prevention and mitigation in the study area but also serve as a reference for regions with analogous geomorphological and geological conditions.Furthermore,the findings offer critical insights for guiding local hazard monitoring,early warning systems,risk management,and emergency response strategies.
