地震灾害风险普查中的危险性计算与数据处理

Seismic Risk Calculation and Data Processing in the Survey of Earthquake Disaster Risk

主要介绍地震灾害风险普查工作中的地震危险性计算与数据处理,基于ArcGIS软件和Matlab、Python程序从标准格网的建立、数据处理、批量绘图和生成word文档的角度进行论述,以湖南省地震危险性计算与数据处理为例,完成了30″标准格网约28万个计算点的地震危险性计算与场地调整,并对地震危险性进行分级,批量绘制了14个地州市和122个区县的地震危险性图件以及批量生成word报告,并从详细的处理步骤与效率等方面进行分析。结果表明,使用ArcGIS软件平台批量绘图、结合Matlab、Python程序代码生成矢量数据shp文件与处理word文档,省时高效且可重复操作性强,可为从事地震危险性计算相关科研工作者提供参考。

This paper mainly introduces the seismic risk calculation and data processing in the survey of earthquake disaster risk work.We discuss the establishment of standard grid,data processing,batch mapping and the generation of word documents based on ArcGIS software,Matlab and Python programs.Taking the seismic risk calculation and data processing in Hunan province as an example,we completed the seismic risk calculation and site adjustment of approximately 280,000 calculation points in 30 second standard grid,and classified the seismic risk.Seismic risk maps of 14 cities and 122 counties in Hunan province were plotted in batches,as well as word reports were generated in batches.The paper detailed processing steps and efficiency were analyzed.We found that the use of ArcGIS software platform for batch drawing,combined with Matlab and Python program code to generate vector data shape files and process word documents,was time-saving,efficient and highly repeatable,which can provide a reference for researchers engaged in seismic risk calculation work.
