摘　　要：以县(市)区域为研究对象,通过分析山洪灾害孕育的暴雨、地形、河流水系等主要影响因子,采用GIS工具进行提取与处理,利用AHP法计算各因子的权重,最后各图层加权综合计算获得县域山洪灾害危险性图,根据历史山洪灾害数据来验证结果的可靠性,以期为山洪灾害风险识别和管理提供科学依据。Taking county （city） areas as research object, by analyzing the main influencing factors such as torrential rain, topography, river system and so on, the paper uses GIS tool to extract and deal with each factor, and calculate the weight of each factor by AHP method. Finally, the county mountain torrents hazard map is obtained by weighted comprehensive calculation of each layer, and the reliability of the result is verified according to the historical mountain torrents disaster data, in order to provide scientific basis for the identification and management of mountain torrents disaster risk.
