摘　　要：本文利用图情领域最新研究成果,提出了空间知识服务的基本概念,并从服务内容、服务对象和服务提供者、服务方式等3个方面对地理信息服务和空间知识服务进行了辨析。为了实现空间知识服务,今后需要在用户知识需求建模、地理空间知识网络构建、知识检索、知识组合和知识可视化等方面做更深入的研究。This paper proposed the fundamental concept of geospatial knowledge service on the basis of the newest research solu- tions in the field of library and information service. Then it critically analyzed the relation between geospatial knowledge service and ge- ography information service in three aspects： service content, service object and provider and service pattern. At last, in order to real- ize geospatial knowledge services, it put forward that people need to do some deeper researches in the four aspects as users＇ knowledge demand modeling, geospatial knowledge network constructing, knowledge retrieval and combination based on semantic web, and knowl- edge visualization.
