| 摘 要： | 采用传统的袭扰系数法划分地质灾害易发区方便易行,但往往忽略了地质环境条件、人类工程活动等因素的重要影响.在MAPGIS技术支持下,采用综合危险性指数评价模型,将地质灾害发育强度、地质灾害形成条件等各因子的权重指数进行叠加,计算单元的综合危险性指数,以此划分易发区,避免了袭扰系数法存在的局限性,划分结果更趋合理.

| Abstract: | The traditional harassment coefficient method is very convenient to divide the geo-hazards prone areas but neglects factors of the geo-environment and people's engineering activities etc.Based on the MAPGIS technology,a composite index model is adopted to compose the weighted indexes of the geo-hazards growth strength and formed situation.According to the risk composite indexes,geo-hazards prone zones are set off,which can avoid the limitation of the traditional harassment coefficient method. |

| Keywords: | geological hazards susceptibility zoning risk composite indexes strength weighing |
