摘要：

从资源环境信息分类编码基本概念与分类对象的依据、数据分层与资源环境信息分类以及资源环境概念数据库与逻辑数据库设计角度，描述国家资源环境数据库信息分类编码的概念模式与分类方法，并在优化、整合现有各类专题资源环境与基础地理信息的分类编码方案的基础上，提出国家资源环境数据库综合信息分类与编码应用模式；指出面向GIS的资源环境信息分类编码是在概念水平上解决空间信息分层组织与属性数据库结构设计的重要方法，它对资源环境数据库视图的建立、系统间的数据共享与互操作具有重要意义；本文还就某些与信息分类编码相关的问题与需要进一步研究的工作进行了讨论。

关键词: 资源环境信息, 分类编码, 概念模式, 应用模式

Abstract:

This paper introduces the fundamental concept, conceptual schema, and the method of resources and environment information classification and coding, and describes the data layer organization, conceptual database, and the logical database of national resources and environment scientific database initiative. It then explores the application schema of resources and environment scientific database by optimization and integration of several thematic resources and environment and geographic information classification and coding scenario. The paper also illustrates the GIS-oriented geographic information classification and coding offers an important solution to the geospatial data coverage arrangement and structure construction of attribute data file in conceptual level, also an important approach for data sharing and semantic interoperability between different applications. Finally, the paper concludes by presenting some aspects of resources and environment information classification and coding, and also suggests the further work on this domain.

Key words: resources and environment information, classification and code, conceptual schema, application schema
