摘要

摘要: 基于目录体系的政务信息资源整合有利于信息资源的共享和交换.针对自然资源和地理空间信息资源的特点，分析了国家电子政务资源目录体系，提出了面向综合决策的自然资源和地理空间信息资源整合改造的数据目录体系，这样的整合方法为信息资源的动态有机整合建立了基础，可以适应信息资源的动态变化，同时通过目录编制明确了数据提供者和共享部门，为信息资源的整合和共享建立长效机制提供了依据.

Abstract: E-government information resources integration based on catalog system are beneficial to the sharing and exchange of information resources. According to the characteristics of the natural resources and geo-spatial information resources, the paper analyzed the catalog system of e-government resources, and then put forward the data catalog system of the natural resources and geo-spatial information resources integration transformation to deal with synthesis decision-making. This integrated approach establishes the basis of the organic integration of information resources, and adapts to the dynamic changes of information resources. At the same time, through cataloging, it can make data providers and share sectors clear, and provides the establishment of long-term mechanism for the integration and sharing of information resources.
