摘　　要：应用GIS技术,以Arcgis为操作平台,对2013年松原市前郭尔罗斯蒙古族自治县发生M 5.8震群后砂土液化地震灾害进行综合分析研究,并建立了此次地震事件砂土液化灾害的数据资料库。利用Arcgis中的Arc Catalog对图形信息、数据属性信息等进行综合管理,方便地震行业相关数据的输入、存储、查询、管理和分析。运用Arcgis中的Arcmap对数据资料进行叠加和空间分析,使此次地震事件中的砂土液化灾害以直观的地图形式展示出来,方便进行更深入的地震灾害研究,也便于决策部门更明确此次地震砂土液化灾害发生的地理位置等情况,为今后的地震灾害研究提供数据基础和可参考的空间分析方法。The sand liquefaction disaster was comprehensively analyzed and researched by GIS technology on Arcgis platform after 2013 Qianguo Mongolian autonomous county M5.8 earthquake swarm, correspondingly, the sand liquefaction disaster database was set up on the Arcgis platform. The information of the database, such as graphical information, data attribute information was managed by ArcCatalog in Arcgis, which was convenient to input, storage, query, management and analysis the earthquake related data. Superposition and spatial data analysis were implemented to intuitively visualize the sand liquefaction hazards map, which was convenient for more in-depth studies of earthquake disaster, also facilitated the decision-making departments more clear the location of seismic sand liquefaction disaster, etc.,. The result can provide basis and referable spatial analysis method for the earthquake disaster research in the future.
