摘　　要：实现地理空间数据由信息管理向知识服务跨越是当前地理信息科学研究热点之一。本文从探讨空间知识地图及其可视化相关理论入手,针对当前地图服务应用需求和发展趋势,研究了地理空间知识分类及其可视化要点、空间知识地图特征等内容,并基于用户与空间知识地图可视化的关联,探讨了空间知识地图可视化系统研究流程模型和关键策略。Currently, the development of geospatial data from information management to knowledge service was considered as one of the hot research fields in geographic information science. Started with the study related to the theory about geospatial knowledge map and its visualization, aiming at current map＇ s application needs and devel- opment trend, geospatial knowledge＇ s classification and visualization, geospatial knowledge map＇ s characteristics and other contents were analyzed in this article. Then the process model and essential strategy which can turn geo- spatial information visualization to geospatial knowledge visualization was researched based on the relationship be- tween users and geospatial knowledge visualization.
