WDC-D地震前兆综合观测数据的抢救和整编
|
摘要
概述了地震前兆综合观测数据抢救和整编的必要性;介绍了前兆观测数据库的选取及特点;系统收集了首都圈范围内(包括5省2市)的地震前兆观测数据,并对其进行分析、整编并入库。通过WDC D项目支持,本专题共抢救和整编了8个单位共304个台站的前兆观测数据,其中专业台121个,地方台183个,共计1709个测项的344M前兆综合观测数据。同时,通过局域网和Internet为研究和分析人员提供了前兆综合观测数据的服务和数据共享。文中分析了WDC D项目数据共享服务的几种方式,即局域网内基于C/S结构的应用、广域网上基于B/S结构的数据下载服务及图形服务方式,并简要分析了这几种数据服务方式的优缺点。最后,在总结和分析所做工作的基础上,提出了几点建议。
The necessity and feasibility of integration and compilation of earthquake precursory observation data is briefly described in this paper. Also, the choice of database and its features are introduced. Earthquake precursory observation data within the Capital Circle Area including 5 provinces and 2 municipalities are systematically collected, analyzed, summarized and stored into CAPOMEN Database. With WDC-D support, the 344M earthquake precursory observation data of 8 departments are obtained and compiled, including 304 stations and 1709 observation methods. Of all the 304 stations, the professional stations are 121, and local stations are 183. Moreover, this system also uses WEB and FTP tools to exchange and share data with other users, and provides many services such as precursory data query, browse and down load for WWW users, which are used CAPOmen platform as the background database and based on Internet browsers. The 3 data share types of WDC-D database are presented, involved in the application based on Client/Server structure within an Intranet, and the data download and graphical service with Browse/Server mode in the Internet. The advantages and disadvantages of these data share services are mentioned in this paper. Finally, some proposals are provided for discussion.
