摘要
国家发改委《青海湖流域生态环境保护与综合治理规划》自2008年正式启动以来,有力地推动了青海湖流域的生态环境保护,积累了丰富的生态环境数据。青海湖流域生态环境综合数据平台是生态监测体系中的数据集成中心,为发掘生态环境监测数据的科学价值,辅助生态环境变化过程中的科学研究,充分发挥青海湖流域生态环境监测体系建设项目的投资效益,并面向青海湖流域的生态环境研究提供科学数据服务。平台依托地理元数据技术,集成了开源GeoNetwork元数据系统,构建了一个集在线元数据编辑、数据可视化、数据汇交、管理、发布和共享等功能于一体的WEB系统,支持缩略图导航、分类导航、时空导航、关键词导航等多种数据导航方式,定义了一套快速数据服务体系,实现了从数据汇交、数据发布到数据共享的业务流程。该系统已初步实现了9个青海湖生态环境监测单位的数据整理与汇交,数据量约为200GB。
Ecological and environmental data in the Qinghai Lake Basin （QLB） have been systematically col- lected since the official launch of the Plan of Eco-Environmental Protection and Integrated Management of the Qinghai Lake Basin in 2008. The Plan has established a comprehensive monitoring system for ecology and environment studies in the QLB. The Data Center for Eco-Environment Protection in QLB （DEEP） is a data portal of the established monitoring system in QLB,aims which to collect,manage and disseminate ec- ological and environmental data to facilitate scientific studies in QLB. DEEP is built upon a geographic metadata architecture that is actually supported by the open source GeoNetwork, by which creation and edi- tion of geographic metadata is implemented. DEEP offers full data sharing functionalities,including metada- ta editing, data collecting, auditing, managing and publishing, as well as data visualization currently only for partial datasets. At present,DEEP holds 76 metadata and a total size of ecological and environmental data- sets of around 200 GB from9 participating organizations. The functional design and key technologies are presented in this paper.
