中文摘要：

从地球信息科学角度，分析了海洋现象的过程特性，并给出过程对象的BNF范式组织结构。把具有过程特性的海洋现象分级抽象为海洋过程对象、阶段对象、序列对象和状态对象，讨论了海洋过程对象的语义分级抽象与顺序、包含关系及过程对象内的演变机制，分析了通过过程对象隐式记录演变机制、过程对象存储表提供其程序接口，实现连续渐变表达机制在模型中的实现策略，发展了基于过程对象、过程对象关系表的模型的过程化组织结构。在Geodatabase9．2基础上，扩展过程对象的存储机制，构建海洋时空过程数据模型的原型系统（海洋时空过程数据库系统MarineSTPDMGDB和海洋系统功能平台MDMProtoTypeSystem），并给出其框架结构及关键技术实现流程。原型系统的构建及功能分析结果证明了模型的科学性与适用性，为“数字海洋”战略的实施提供了理论基础。

英文摘要：

In the view of Geo-information science, this paper analyzed the process characteristics of oceanic phenomena and gave the organizational structure of process objects based on BNF. Oceanic phenomena with process properties were hierarchically abstracted as Marine Process Objects, Stage Objects, Sequence Objects and State Objects. The hierarchical abstraction, the sequential and inclusive relations of marine process objects and its evolution mechanism were discussed. Besides an evolution mechanism being implicitly recorded by Process Objects and its procedures interface being provided by Object Storage Table, a strategy of continuity and gradual representation mechanism built-in marine data model was done. This paper also proposed the model＇s process organizational structure based on process objects and their relationship tables. On the basis of Geodatabase 9.2, the expanded storage strategy of process objects was developed, and the prototype system, which included marine spatio-temporal process object database system （Marine STPDMGDB） and marine system functional platform （MDM Proto Type System）, was constructed. Andthen the framework structure and the realization flow of key technology of prototype system were presented. Scientific value and applicability of the model have been proved by the construction of prototype system and the results of function analysis, which will provide basic theories for building ＂Digital Ocean＂.
