中国"数字国土"工程的方法论研究

“数字国土”是新世纪的一项宏伟工程,也是对“数字地球”和“数字中国”战略计划的响应,其核心问题是分布式点源空间数据库和属性数据库建设。分布式主题数据库建模,“多S”结合与集成,三级网络结构,信息标准化体系,海量数据入库,计算机辅助设计等关键技术的攻克,是实现区域地质调查了与矿产资源的信息化前提,而信息安全是“数字国土”的保障,作为合理而完善的解决方案,除了制定总体规划和系统结构外,还应当制定切实可行的对策和实施步骤,这需要借鉴国际上国土资源信息系统建设和地球信息科学方向发展和最新成果,并根据我国国土资源勘查与管理的特殊布局,通过周密的系统分析和系统设计来制定。

Discussion on Methodology of "Digital Land and Resources of China" Project

Digital State Land and Resources", a grand project in the 21st century, is a response to the state strategic plans called "Digital Earth" and "Digital China", respectively. Its core is the construction of distributed point source spatial database and attribute database. The important problems of technology are the modeling of the subject database, the "multi S" integration, the three level network structure, the computer aided design of geological maps, the information standardization system, the entry of numerous data to the database and the information security. This grand project needs a set of logical and perfect solutions. Problem shooting countermeasures and procedures are suggested that have incorporated latest achievements in the construction of land and resources information system in the world and those in the development of geoinformatics, and followed the overall system analysis and system design in line with the special pattern of the Chinese land and resources exploration and management.
