中文摘要：

针对现有时空数据模型研究中存在的诸多不足,特别是基于事件的时空模型缺乏以空间对象个体为单位的时空变化贯穿式表达能力等缺点,提出一种基于事件的双序列时空数据模型,将状态变化与空间对象的变化用双重序列表达,用序列存储对象的变化解决了现有时空数据模型基于空间对象个体时空变化信息表达能力弱的问题.实验表明,该模型可有效用于时空数据管理.

英文摘要：

Spatio-temporal data model is one of the focuses as well as difficult issues in the spatio-temporal database and spatio- temporal GIS research. To overcome the shortage of existing spatio-temporal data models, especially the evenwbased model lac- king the ability to describe the spatio-temporal changes on spatial entities, the paper present an event-based dual-lists spatio- temporal data model. The model will express the spatio-temporal changes by double lists to solve the problem of lacking the a- bility of spatial entities individual spatic-temporal changes expression that is existing in spatio-temporal data model. The experi- mental results show that the model presented in this paper is valid in managing spatic-temporal data.
