摘　　要：Based on the experience and achievement of the＂China Digital Ocean＂, the classification plan for Marine data elements is made, which can be classified into five, including marine point elements, marine line elements, marine polygon elements, marine grid elements and marine dynamic elements. In this paper, the technology of features and object-oriented method, a spatial-temporal data model is proposed, which can be applied in the large information system engineering like the ＂Digital Ocean＂, and this paper discusses the application of spatial data model, marine three-dimensional raster data model and relation data model in the building of Data Warehouse in ＂China Digital Ocean＂, and concludes the merits of these models.基于中国数字海洋建设的经验和成果,制定了海洋数据要素的分类方案,将海洋信息分为5大类:海洋点要素、海洋线要素、海洋面要素、海洋网格要素、海洋动态要素。采用基于特征的方法和面向对象的技术设计了适合数字海洋大型信息系统工程建设的时空数据模型,探讨了海洋空间数据模型、海洋立体格网数据模型、关系数据模型在数字海洋数据仓库建设中的应用,并总结了其优缺点。
