With the implementations of global-change and other major science programs, there is an urgent need to collect and share multi-source heterogeneous mass of data at regional and even global scale systematically. Traditional data centers only provide downloading service, which significantly lacks services to diversified needs of users. Therefore, it is one of the main directions of data sharing network development to meet the demand for users and achieve spatially displaying and data mining based on GIS technology. Taking the construction of climate and sea-level change dataset in the Geodata-sharing network as an example, aiming at the management and retrieval of geo-scientific datasets, based on research of climate and sea-level change data model, in this article we carried out unified planning, designing and management of the related databases. Furthermore, ASP.NET, ADO. NET system development environment are used to build the retrieval system of climate and sea-level changes based on .NET and ArcIMS technologies. Users in a unified platform can achieve single retrieval such as basic data, thematic themes, spatial contents and literature searches or multi-angle integrated retrieval. Simultaneously, with the application of GIS, a number of data analysis and data mining functions are achieved preliminarily and the literature and related geodata visualization are also achieved. The user-oriented services to unified storage management, publication, retrieval and sharing are accomplished preliminarily, which is a valuable attempt to science data centers by converting the simplex data downloading centers to the multi-functional data service centers.
