摘　　要：地震数据集成共享在地震监测与分析中具有重要作用。为此,针对传统基于数字图书馆的地震数据集成化共享方法集成度低、共享率差的问题,研究一种新的地震数据集成与共享方法,该方法分为两个阶段,先是利用数据仓库技术对地震数据进行集成,包括数据抽取、清洗、归约、装载等;后建立共享平台,完成数据透明式访问,实现数据共享。结果表明:利用该文章所提出的方法对大规模地震数据进行集成化共享,集成度达到95.68%,共享率达到87.34%,为遥测地震监测与预防提供了有效的数据查询平台。Seismic data integration and sharing play a significant role in seismic monitoring and analysis.The conventional digital library-based seismic data integration and sharing method have the problems of low integration and poor sharing rates,so a new seismic data integration and sharing method are studied.The method is divided into two stages.First,seismic data is collected using data warehouse technology,including data extraction,cleaning,reduction,loading,etc;then a sharing platform is set up to complete the data transparent access,and the data sharing is realized.The results show that the proposed method’s degree of integration and sharing rate can reach 95.68%and 87.34%,respectively,providing an efficient data query mechanism for seismic monitoring and prevention of telemetry.
