Abstract5.12 大地震发生后,成都市的都江堰等西部 5 个市县均遭受了不同程度的破坏。因此,地质灾害风险管理显得尤为重要。通过 GIS 技术,利用贡献率叠加模型对研究区域进行 3km×3km 的格式化处理,叠加地质灾害中各个因子图层,得出危险性等级区划图。再通过对承灾体的调查确定承灾对象,对承灾体进行易损度等级划分图。最后将危险度与易损度进行叠加得到风险区划等级划分图。风险区划图不仅有利于对地质灾害风险进行管理,而且为灾后重建整体规划提供直接的参考依据。
Other AbstractWenchuan earthquake caused great damage to Dujiangyan and other four counties of Chengdu. So it is important to the geological disasters risk management . The research area were divided to 3km×3km grids by the GIS technology and contribution weight model. We can get the zoning map of hazard by superposition layers of geological disasters and the zoning map of vulnerability by the analyzing the main disaster. After these two steps the risk zoning map is achieved .The zoning map is not only help to the geological disasters risk management, but also provide for the overall planning of post-earthquake reconstruction.
