数字省、数字城市建设是数字地球的重要方面和基础 ,具有现实意义和价值 ,可操作性高。在进行数字省建设过程中 ,迫切需要各部门之间的信息共享 ,特别是大比例尺空间基础信息和公共基础信息。信息共享平台将在各部门建立分布式的网络分中心 ,对各部门现有的数据库进行规范化、网络化和空间化改造 ,建立信息共享体系。本文以福建省政务信息共享平台为例 ,详细分析了数字省信息共享平台的总体结构设计、模块功能设计及实现过程 ,并就系统实现过程中的体会及今后发展方向进行了讨论。

The construction of Digital Province and Digital City serves as the base and constitutes an important actor of Digital Earth During the construction of Digital Province, the reconstruction and exploitation of the existing information resource and information sharing among government departments are important components of Digital Province So it is necessary in the process of construction of the distributed information sharing platform to standardize the reconstruction, realize information sharing among all the departments and avoid repetition of information construction. This information sharing platform will build distributed network center in every relevant department to deal with the above task This paper takes Fujian Province as a case to analyze in detail the structure of Government Information Sharing Platform of Fujian Province, which includes various linkages that form an integrated structural framwork such as the research and development of information sharing policy as well as standard and technology; the construction of information sharing software and hardware; the development of government Office Automation system; the reconstruction of standardization, networking and spatialization; the construction and update of government basic information database; the reconstruction and integration of the existing application system The Fujian Province Information Sharing Platform is made up of seven sub systems, including platform management system, metadata management and data dictionary system, database management system, data management system, data handling and analysis system and data presentation system The paper introduces the components of each sub system and its function At last the system realization process is described in detail The author also discusses the development direction in the future
