面向黑河流域生态水文过程集成研究的科学数据汇交与管理

科学数据汇交是科学数据共享的重要数据支撑,在重大科学研究计划中更需要考虑数据的汇交与共享。国家自然科学基金委员会于2010年正式启动了“黑河流域生态-水文过程集成研究”重大研究计划(以下简称“黑河计划”)后,就将黑河计划的数据汇交与管理进行了多次讨论,于2012年推出《黑河计划数据汇交与共享管理条例》(以下简称“管理条例”),由黑河计划数据管理中心负责具体执行。黑河计划数据管理中心基于管理条例,设计并实现了面向黑河计划的科学数据汇交管理系统。回顾了科学数据汇交的发展现状,介绍了管理条例的核心内容,设计了黑河计划数据汇交的技术流程,并将数据提供者的权益保护嵌入到数据服务流程中,并根据黑河计划特点进行数据共享管理。针对数据汇交系统在实现中的关键技术问题进行了讨论,包括集成GeoNetwork系统实现元数据的撰写、以提高数据质量为目标的数据审核、高效的数据服务以及数据的知识挖掘4个方面。

Design and Implementation of Data Collection System for Integrated Research on the Eco-hydrological Process of the Heihe River Basin

Data collection could play an important role in the promotion of science data sharing,it is especially important in the major scientific research programs.While the integrated research on the eco-hydrological process of the Heihe River Basin (hereinafter referred to as “Heihe Plan”) was officially launched in 2010 by National Natural Science Foundation of China,the rule of data collection and sharing was also discussed by the experts of the Heihe Plan,and it was carried out in 2012 by the Heihe Plan data center.The current development of the scientific data collection was reviewed,then the core of the rule of data collection and sharing of the Heihe Plan was introduced,a series of workflow were designed for the data collection system with protecting the intellectual property of the collected data.The key technologies are discussed from four aspects in the implementation of the data collection system:the integration of GeoNetwork,the data auditing system to promote the data quality,the fast data service system and the data mining supporting system.
