摘要：
Wenchuan 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 3kmx3km 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.
