对国家科学数据共享工程中地球系统科学领域数据资源的元数据信息进行抓取和处理,从不同的角度进行统计分析,展现当前地球系统科学领域已共享科学数据资源的基本情况,然后重点研究了科学数据资源的采集、生产和发布机构的特征及地域关系。结论表明:此领域科学数据的共享已具有一定的数据采集、生产和发布流程,相关机构及数据涉及的研究区域分布也形成一定的特征,但已共享科学数据资源量比较小,对科学数据的管理和共享处于初级阶段。

The metadata information of earth system science field data resources with China Scientific Data Sharing Project (SDSP) are downloaded and processed, from different angles, statistics and analysis on the metadata are conducted. The profile of the status quo of scientific data resources in earth system science field under the SDSP is presented. The data collection, production, and publish of scientific data resources and their geographical relations are focused on. The results show that scientific data sharing in the field has already formed a certain model for data collection, production, and publish; research region distribution for the data resources and relevant institutions has shaped a certain pattern. However, the quantity for sharing scientific data resources in earth system science field is quite small, scientific data management and sharing is in their initial stage.
