| 摘 要： | 简单论述了地理本体的基本概念、结构，介绍了地理本体的建模方法，提出了基于地理本体的空间数据集成框架，采用基于公共属性模板的多本体向标准本体集成的混合构架，以水系要素中的“干出滩”类为例，实现了基于地理本体的空间数据集成过程及其数据的转换，解决了数据语义异构性所带来的数据共享难题。

| Abstract: | This paper briefly introduced the basic concepts, components and construction methods of geo-ontology. Integration framework of geospatial data based on geo-ontologies was presented. Geo-ontology integration is a hybrid architecture based on the common intension properties template. Finally, taking the class of dry shoal which is an element in hydrologic feature as a case study, it realized the progress of geo-ontology integration and the data transi- tion method. The difficult problem of data share caused by semantic heterogeneous was solved by this way. |
