摘　　要：传统的基态修正模型仅能显式存储宗地变更的父子关系和变化类型,不能在2个不同时间快照间进行关联检索.在已有时空数据管理方法的基础上引入地理事件,通过事件序列组织差文件来解决前后版本数据库之间时态拓扑关系和空间拓扑关系关联的难题,根据时空地理对象的空间拓扑关系和时态拓扑关系模型,提出了81种时空拓扑关系并进行综合呈现.通过地籍数据库增量更新过程进行验证,结果表明,提出的模型能够较完整地存储与表达该模型下的时空拓扑关系,可以通过改进的STSQL语言进行时空查询,在时空数据的管理上具有一定的应用价值.The traditional model of the base state with amendments can only record explicitly the changes of parentchild relationships and the types of parcels,but it can＇t solve the problem of associated query between two different time snapshots.The theory of geographical events was introduced and the events increment files were used to solve the association problem of temporal topology and spatial topology between different versions of the database.Combining the model of temporal topology with that of spatial topology,81 kinds of spatio-temporal data topology relations were comprehensively displayed.In terms of the verification of the incremental updating process of cadastral database,the above-mentioned model can fully show and store the spatio-temporal topology relationships,and implement the spatio-temporal query by the improved STSQL language.It can express the temporal and spatial topological relations intuitively.This model can be applied in spatio-temporal data management.
