摘　　要：随着空间地理信息以及各种新型地图产品在各个领域的广泛应用,人们发现不同时期,应用需求对空间地理信息组织表达的要求是不同的,不同领域和部门对地理信息的组织表达方式也是不同的。但是,目前空间地理信息的共享和互操作、空间地理信息的多尺度分析与表达等,都要求空间地理信息的组织与表达要科学、合理和规范,否则难以满足测绘信息服务化及信息化测绘体系的建设。本文以交通类信息组织表达为例,详尽阐述当前空间地理信息组织表达的现状,分析其原因,并提出了解决这一问题的思路和方法,为今后信息化测绘体系建设、数据库数据组织和地理信息表达,提供理论和方法借鉴。With the wide application of spatial geographic information and multifarious new map products in various field, it is found that the demands for organization and expression of spatial geographic information are different in different periods and for different departments. But, nowadays it is required that the organization and expression of geography information should be scientific, reasonable and normative in the sharing and interoperability of spatial geography information, the spatial geography information＇ s multi- scale analysis and expression, and so on, Otherwise, the service-based mapping information and information-based mapping system can＇ t be built. Taking example for the organization and expression of traffic information, this paper introduces spatial geography information＇s actuality in detail, analyses the reasons, and puts forward the solutions and methods, proposes references of information- based mapping system＇ s construction, database＇ s data organization and geography expression at the aspects of theories and methods.
