摘　　要：地理空间信息的图形符号显示标准化是地理空间数据规范化的重要组成,也是其走向数字化、网络化和移动化的必备条件,以确保地理空间信息在感知和认知上的一致、有效和准确,提高其通用性使之能在更广泛领域中沟通和共享。本文通过参照有关国际国家标准和对大量相关文献的调研,对符号分类体系、显示介质、视觉感知、视觉变量、分级表达、颜色标准等方面进行了探讨,以期对地理空间信息图形符号的显示标准的制定提供一定参考或借鉴。Standardization of graphic symbols being used for geospatial data display is a formidable task in facilitating applications of spatial data in a wider range of fields and disciplines. This way, geospatial information can be ensured of its consistency, effectiveness and accuracy in both perception and cognition during its transmission process. This study reviewed relevant international and domestic standards and literatures on spatial data representation and discussed such digitally-based spatial data visualization issues as symbol classification system, display medium, visual conception, visual variable, classification display and color standard. It provided some suggestions on the future formalization of a standardized graphic symbol system for computer screen display of geospatial information.
