中国可持续发展信息共享系统设计与关键技术研究

摘要

China's Sustainable Development Information Sharing System Nis a spatial data management and analysis system that possesses the base functions of web-GIS. Chinese sustainable development information can be accessed through this system. These data include information of vegetation and animals resources, microbe species, crop species, forest, land use, nature protected area, geology and mineral resources, ocean resources and environment, climate and integrated information of disasters. This paper illustrates the general content of Geo-Information sharing and its realization in Internet. Some technologies of information construction, search and retrieval, while specific to Sustainable Developing Information Sharing Network project, are described in details.%根据国家“九五”科技攻关项目《中国可持续发展信息共享示范》的目标要求，结合大容量可持续发展属性和空间信息的网络共享特点，从系统的结构、功能，可持续发展信息的规范化和网络化改造等方面进行研究与设计。其中包括：可持续发展信息共享网络体系结构、多元异构数据库的集成、可持续发展信息多站点综合分析与分布式计算、统计信息的空间化表达方法及空间多元统计分析和信息共享安全保障等信息共享关键技术问题。
