摘　　要：在地球系统科学数据共享网的长江中下游分节点建设中,全球气候-海面变化在中国东部地区的区域响应,是该节点系列数据库群建设的三大科学主题之一。在GIS技术和数据库技术的支撑下,通过对数据集建设的整体规划与技术实现,可望由通常的科学数据下载中心向科学数据服务中心转变。针对区域地球系统科学研究的需要,本文以气候-海面变化数据集为例,探讨了该数据集的建设目标,进行了数据集的整体规划与设计,该数据集由6个不同主题的科学数据库和文献库构成,文献库不仅是数据集的重要组成部分,同时历史文献也是重要的数据来源之一。进而讨论了数据库设计的区域编码规则、表结构和元数据描述;将数据检索划分基本数据、专题、空间和文献检索四类,并对用户检索的流程和机制进行了探讨。最后指出了以科学数据收集分析为目标进行数据集建设所需注意的相关问题。When constructing the GEODATA （Chinese Earth System Science Data Sharing Network） segment nodes of middle and lower reaches of the Changjiang River, regional response of East China to the world climatesea level change is one of the three science themes. Supported by GIS and database technology, through integrated programming and technologic implementation of the dataset, the science data download center will be transferred into the science data service center hopefully. Taking climate ＆ sea level change dataset as an example, this paper discusses the goal and carries out integrated planning and design of this dataset which is aimed at the research needs of regional earth system science. This dataset was constituted by scientific databases in six different themes and a literature e-library, being not only the vital part of database but also one of the important data sources of the historic literature. What＇s more, it discusses regional coding rules, table structures as well as metadata descriptions of database design, and data retrieval could be divided into four parts, namely, basic data, theme, spatial and literature search. Subsequently, its users＇retrieval process and mechanisms are probed. Finally, some related problems are pointed out in the dataset construction aiming at data collection and inspection.
