摘要
针对当前地球物理勘探数据库系统一系列普遍存在的问题,如专业数据结构设计的复杂性、对数据处理加工要求和缺乏对专项成果数据的有效管理,开展了基于深部探测岩石圈结构的大地电磁测深成果数据库设计与实现。本课题以大地电磁测深基本理论、数据库技术和计算机技术为基础,收集以深部探测为主的全国各大区域大地电磁测深资料,并对其进行整理、分析和建模,设计与开发基于SQL Server 2005和Visual Basic 6.0的大地电磁数据库系统。该系统不仅可快捷地实现数据的检索、查询、编辑、输入、输出等基本功能,而且可进行大地电磁成果图件的存取和可视化操作。同时,本系统的研发将对开展中国岩石圈结构、地球动力学和地球构造演化的研究起到重要的技术支撑作用。
In view of the existence of a series of common problems in the current geophysical database system,such as the complexity of professional data structure design,the requirement of data processing and the lack of effective management of specific outcome data,the authors carried out the design and implementation of Magnetotelluric Sounding（MT） result database based on the deep lithosphere structure.On the basis of the basic theory of MT,database technology and computer technology,the authors collected,trimmed,analyzed and modeled MT data that are the major regional deep exploration data,and,on such a basis,designed and developed the MT database system based on SQL Server 2005 and Visual Basic 6.0.Some basic functions of the system that include retrieval,query,edition,and input / output can be achieved quickly and easily,and other functions of the system that include MT storage and visualization can be operated as well.Meanwhile,this MT database system can play an important technical support role in the study of China＇s lithosphere structure and geodynamics as well as the study of tectonic evolution of the Earth.
