中文摘要：

地理时空对象的变化过程实质上是地理事件序列的集合,地理事件的检测是实现空间数据库自动更新的关键所在.为提高时空数据更新的自动化水平,以土地利用数据更新为例,通过对地理事件概念、特征的分析,定义了5种地理事件类型.在此基础上根据专题数据的空间拓扑约束、语义逻辑约束以及拓扑语义约束,结合空间相似度理论,提出了一种基于拓扑与空间相似性的地理事件检测方法,定义了原生事件和次生事件,并以此描述地理事件间的衍生关系.在土地利用现状管理信息系统中的应用,证明了该检测方法在土地利用数据更新过程中的可行性和有效性,为事件更新的进一步自动化奠定了基础.

英文摘要：

The change process of geographical spatio-temporal objects is essentially a set of geographical event sequences,so geographical event detection is the key to realize the automatic updating of spatial database.To improve the automatic updating level of spatio-temporal data,taking data updating land use of as an example,five types of geographical events were defined by analyzing the concept and features of geographical events.Then,according to the thematic data constraints of spatial topology,semantic logic and topo-semantic,combined with the spatial similarity theory,this paper proposed a method of geographical event detection based on topology and spatial similarity,and defined protogenic event and secondary event to describe the derivative relationship between two geographical events.The application in land use data management information system proves that the detection method has practical feasibility and effectiveness in the process of land use data updating,which lays the foundation for further automation of event updating.
