【摘要】 空间数据仓库是在数据仓库基础上对空间数据的扩展。建设地震空间数据仓库对研究地震的时间、空间、时空上的发生、发展规律,及开展地震的预测、预报、防灾、减灾工作具有重要的指导意义。我国的华北地区地震活动频繁,地震记录从历史、数量、完整性等各方面均优于中国其他地区,因而尝试构建中国华北地区地震空间数据仓库,开展了空间数据仓库构建方法的研究。更多还原

【Abstract】 Spatial data warehouse is the extension of data warehouse on the basis of spatial data. Building seismic spatial data warehouse is important for studying the law of seismic activity in time sequence, spatial area, and spatio-temporal distribution, as well as earthquake forecast, prevention and reduction. Earthquake happens very frequently in North China. Its seismic data records are superior to other areas of China in aspects of precision, quantity, and perfection. So the authors tried to build a seismic spatial data warehouse of North China for the study of the method of building spatial data warehouse.更多还原
