英文摘要	In order to integrate distributed and isomerous earth system scientific data resources and provide one stop data sharing services for different users, a distributed data sharing platform is needed urgently in China. In this paper, we analyze interoperability requirements of the distributed earth system scientific data sharing platform (ESSDSP) in the first place. Then the general framework of the platform based on service-oriented architecture (SOA) is designed. This platform comprises one main center, one authentication center and several sub-centers in which core functions are encapsulated into web services. Through this incompact architecture, it can not only implement the interoperability among distributed data centers, but also easily integrate other software systems. Furthermore, these web services can be accessed by third party software such as e-business, e-government and so on to achieve data sharing function. Finally we introduce the design, implementation and deployment of some core web services in detail, i.e. data centers' information synchronization service, distributed metadata synchronization management service and multi-resource data access service. This platform was deployed in Earth System Scientific Data Sharing Network(ESSDSN), one of National Infrastructure and Facility Development Environment Building for Science and Technology Industries Program of China. In practice, it comprises one main center, one authentication center and 13 sub-centers. So far, if has integrated 10.23 T Byte data resources and 17 T Byte data resources have been downloaded by 34,597 users.
