摘要
以紫阳县地质灾害为研究对象,以ArcGIS为平台,通过选取地形地貌、构造岩性等评价因子,采用确定性系数法的概率分析,对地质灾害的诱发因素进行概率统计,进而建立量化指标体系,采用GIS叠加分析,完成了对紫阳县地质灾害发育环境、发育类型和分布规律、危险性评价等工作的研究。
This article is based on the geological hazards in Ziyang county to be the object of study, with ArcGIS as a platform, by properly selecting evaluation factors of topography and geomorphology and structural-lithologic, etc, and uses the certainty factor method to ensure the inducing factor grades of geological hazards and establish quantitative index system. The GIS overlay analysis function is taken to finish the study of the developing environment, developing type, distribution law and hazard assessment of the geological hazards in Ziyang county.
