摘　　要：地震应急基础数据库是综合地区自然地理、社会人文经济、行业统计、开展救援等相关数据的综合性数据库,在地震应急、震害防御过程中发挥重要作用,是地震应急指挥技术系统的重要组成部分,其建设和更新具有复杂性、艰巨性和长期性的特点。随着互联网地图的兴起,产生海量的POI数据,具有覆盖面广、种类覆盖度高等特点,因此,考虑将其作为更新地震应急基础数据库的一个重要数据来源。通过分析二者的数据结构特征,提出3种有针对性的更新模式。并以学校数据的更新为例,讨论数据更新的具体方法。经验证,该方法能对地震应急基础数据库进行查漏补缺,较好地完善地震应急基础数据库。The earthquake emergency basic database is a comprehensive database that integrates natural geographic,socio-economic,industry statistical,and rescue-related data.It plays an important role in earthquake emergency response and seismic damage prevention and is the lifeblood of the earthquake emergency command and control system.Its construction and updating are complex,arduous,and long-term.With the rise of internet maps,massive POI data has been generated,which has the characteristics of broad coverage and high category coverage.Therefore,it is considered an important data source for updating the earthquake emergency basic database.By analyzing the data structure characteristics of the two,three targeted update modes are proposed.Taking school data updating as an example,specific methods for data updating are discussed.The results show that this method can identify and fill gaps in the earthquake emergency basic database,and can effectively improve the completeness of the earthquake emergency basic database.
