GIS技术在地质灾害危险性预测评价中的应用

Application of GIS technique in geological disaster risk prediction evaluation

以GIS技术为依托,结合层次分析法,介绍了地质灾害危险性预测评价方法,并以青藏铁路拉日段为例,采用层次分析法建立了研究区地质灾害危险性评价体系,同时利用Arcgis软件强大的空间数据分析与处理功能进行计算,最终得出研究区地质灾害危险性预测评价分区图。

Based on GIS technology, combining with analytic hierarchy process, the paper introduces geological disaster risk prediction evaluation methods. Taking Lari section of Tibet railway as an example, it establishes geological disaster risk prediction evaluation system by applying analytic hierarchy process, applies strong spatial data analysis and treatment functions for computation by applying Arcgis software, and finally achieves geological disaster risk predication evaluation distribution chart.
