Therefore, on the basis of introduction of new con-cept of oceanographic ontology, an oceanographic ontology-based spatial knowledge query (OOBSKQ) method was proposed and de-veloped. Because the method uses a natural language to describe query conditions and the query result is highly integrated knowledge,it can provide users with direct answers while hiding the complicated computation and reasoning processes, and achieves intelligent,automatic oceanographic spatial information query on the level of knowledge and semantics. A case study of resource and environmen-tal application in bay has shown the implementation process of the method and its feasibility and usefulness. 关键词：海洋学数字海洋空间信息 OOBSKQ
