| Abstract: | Based on the geological hazard investigation and zonation project in Jiulong County of Sichuan Province, the paper has researched the character and the contribution factor of the geological hazard, then discussed the application of GIS technology on the evaluation of geological hazard in Jiulong County, and depicted the route of risk evaluation based on GIS technology. Such as selection of evaluation factor, division of grid element, and result evaluation are the main parts of this study. The risk evaluation of geological hazard in Jiulong County which based on GIS can improve, the efficiency and the veracity of geological hazard risk evaluation, show its great superiority. |
