摘　　要：采用组合赋权与地理信息系统(GIS)技术,对雪崩灾害的危险性进行了全面评估。首先,通过文献调研和实地考察,确定影响雪崩灾害发生的关键因素,包括气候、地形条件、以及其他相关因素;采用AHP和熵权法进行组合赋权确定综合权重,以反映各因素对雪崩灾害的不同影响程度;此外,利用GIS技术对综合权重进行空间分析和可视化表达,构建雪崩灾害危险性分布图。综合运用组合赋权和GIS技术,对禾木乡道X852线的雪崩灾害危险性进行有效评估。Combined weighting and geographic information system(GIS)technology were used to comprehensively assess the risk of avalanche hazards.Firstly,through literature research and field investigations,the key factors affecting the occurrence of avalanche disasters were determined,including climate,topographic conditions,and other related factors.AHP and entropy weight methods were used to determine the comprehensive weights to reflect the different impacts of various factors on avalanche hazards.In addition,GIS technology was used to analyze and visualize the comprehensive weights in space and construct an avalanche hazard risk distribution map.Combined weighting and GIS technology were used to effectively assess the risk of avalanche disasters on the X852 line of Hemu Township Road.
