摘　　要：文章结合九龙县地质灾害调查与区划项目,在对全县地质灾害特征和影响因素调查基础上,探讨了GIS技术在九龙县地质灾害危险性评价中的应用,描述了GIS图形处理和空间分析功能支持下的地质灾害危险性评价思路,并介绍了评价因子选取、栅格单元划分、结果评价等问题。分析结果表明,将GIS技术应用于九龙县地质灾害危险性评价中可以提高评价效率和准确性,评价效果较好。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.
