“华北克拉通破坏”重大研究计划共享数据库及其科学意义

The shared database system of the key research project on “destruction of the North China Craton” and its scientific significance

在国家自然科学基金"华北克拉通破坏"重大研究计划支持下,在华北克拉通开展了宽频带地震流动台阵观测和人工源地震剖面探测,以及与克拉通破坏相关的地质和地球化学观测实验研究,产生了多种类型的海量地学观测数据.为了统一管理和充分利用这些宝贵的观测数据,建立了共享数据库系统.该系统基于Oracle大型数据库技术、ArcGIS技术和现代网络技术进行设计,采用成熟的B/S结构并遵循J2EE的MVC三层架构模式以Java语言进行了开发.系统实现了对相关观测数据的汇集、管理、处理和共享服务功能,提供了基于Internet的方便快捷的检索下载,以及基于WebGIS的图形化服务."华北克拉通破坏"重大研究计划共享数据系统的建立和数据共享,将有利于科学观测数据的深入挖掘和多学科综合研究,对实现该计划提出的研究目标及相关地学研究都具有重要的科学意义.

Under the support of the key research project on＂Destruction of the North China Craton（DNNC）＂set up by the National Natural Science Foundation,many research projects of have been carried out. These projects involve broadband seismic array observations,artificial deep seismic profiles,observation and experiment of geology and geochemistry.And they have produced many types of mass geoscience observation data.In order to manage systematically the observation data,the shared database system has been set up.The system is designed on the basis of the Oracle large-scale database、ArcGIS and internet technology, and developed by the B/S architecture,MVC three layer architecture model and Java program language.The system has the functions of data collection,storage,procession and sharing service.It can provide the convenient and fast searching and downloading,and graphical service by the WebGIS.The shared database system will promote the comprehensive utilization of observation data and multi-disciplinary comprehensive research.And it has important scientific significance to achieve the scientific research goal of the project and develop related research.
