摘要： 在基于有向三角形的空间数据模型的基础上，融入了时态信息的存储、表示及操作，形成了一个较为完善的时空数据模型。该模型较好地处理了时态信息和空间信息的关系，为时空查询语言的研究与设计奠定了良好基础。

Abstract: This paper proposes a relatively complete spatio-temporal data model that integrates storage, representation and operation of temporal information with the spatial data model based on directed triangulation.The model well handles the relationship between temporal information & spatial data, which sets good foundation for research and design of spatial-tcmporal inquire language.
