古生物地层数据库建设及其意义

Construction of the biostratigraphic database and its significance

古生物地层数据库建设是一项长期而意义深远的学科基础工程。严格规范建库流程,建立古生物地层数据库数据关系和框架结构,开发运行软件,设置多种查询功能,突出实用性,实现成果共享。在新一代古生物地层资料收集、整理和研究基础上,尝试建立《中国地层标志化石数据库》。利用计算机技术,使资料系统化、标准化和数据化,完善中国年代地层表,统一地层划分对比标准,解决一些科研问题。建设涵盖各地质断代和全国范围的古生物地层学数据库,加强基础学科技术支撑作用,促进学科发展。

Construction of a biostratigraphic database is a long-term basic disciplinary project of far-reaching significance. The construction work includes standardizing the database construction flow process stricdy, establishing the biostratigraphic database data-relationship and framework, developing operating system softwares, setting several inquiry functions, giving prominence to practical applicability and sharing achievements. The stratobiomarks database of China （Web edition） has been constructed recently based on collection, collation and study of biostratigraphic data. The computer technique is used to systematize, standardize and digitize the data, improve the Chronostratigraphic Table of China, unify the standards of stratigraphic division and correlation and solve some scientific problems. The construction of the biostratigraphic database involves all geologic ages and countrywide biostratigraphic databases, and it can strengthen the techno-support function of the basic discipline and promote the development of biostratigraphy.
