地球系统科学数据共享软件研究与发展

Research and Development of Software of Earth System Science Data Sharing

地球系统科学数据具有分散、多源、异构、海量等特点，是全球变化创新研究和区域可持续发展决策等的重要基础。为了能够有效集成、共享这些数据资源，自2003年起在科学数据共享工程、国家科技基础条件平台等的支持下，开展了地球系统科学数据共享软件系统的研究。在回顾地球系统科学数据共享软件发展历程的基础上，重点介绍分布式地球系统科学数据共享软件的业务模式、总体架构、功能体系和部署应用情况。进一步剖析分布式地球系统科学数据共享软件存在的问题及面向长期运行服务的需求，结合云服务、Web2．0、移动通讯等新技术发展，指出地球系统科学数据共享软件下一步的重点发展方向。

Earth system science Data is dispersed, multi-sourced, heterogeneous, and massive in volume, which lays an important foundation for innovative research of global changes and regional continuous development. In order to integrate and share such data resources, with the support of Science Data Sharing Project and National Sci-Tech Infrastructure since 2003, China has conducted research on the Earth System Science Data Sharing Software. This paper focuses on the introduction of the business mode, general architecture, function system, and deployment and application situations of the distributed Earth System Science Data Sharing software. In addition, it analyzes the problem of this software and the requirement for long-term operation services. Together with the development of new technology, such as Cloud services, Web 2.0, mobile communication, this paper points out the orientation for the software system of earth system science data sharing in the next phase.
