禁核试核查地震信息系统数据库实现技术研究

Research on database realization technology of seismic information system in CTBT verification

切实保障《全面禁止核试验条约》(Comprehensivenuclear-TestBanTreaty,CTBT)真正得到履行的主要技术手段是发展CTBT核查技术,以地震信息系统为基础的地震分析技术已经成为最为主要的技术手段。以GIS为基础建立地震信息系统,可以充分发挥GIS的强大的空间数据分析、拓扑分析和数据可视化处理能力。然而,地震信息系统数据库性能是整个系统功能实现的关键环节。通过分析传统地理信息管理中空间数据与属性数据分离管理模式的缺点,利用ArcSDEGeodatabase数据模型与大型关系数据库管理系统ORACLE结合,真正实现了空间数据与非空间数据一体化的无缝集成,并保留了Oracle的海量数据管理、事务处理、记录锁定、并发控制、数据库等功能。

<Abstrcat> Developing CTBT verification technology has become the most important method that makes sure CTBT to be fulfilled conscientiously. The Seismic analysis based on seismic information system (SIS) is playing an important rule in this field. Based on GIS, the SIS will be very sufficient and powerful in spatial analysis, topologic analysis and visualization. However, the critical issue to implement the whole system function depends on the performance of SIS DB. Based on the ArcSDE Geodatabase data model, not only have the spatial data and attribute data seamless integrated management been realized with RDBMS ORACLE really, but also the most functions of ORACLE have been reserved.
