摘　　要：针对二维欧氏空间内的移动区域对象在时空关系变化建模中存在的问题,该文提出了一种时空关系变化序列模型,并建立了时空关系变化概念邻域图。采取基于时间片的时空数据模型,通过分析移动区域间随时间变化的拓扑、距离和方位关系,解决时空关系变化的集成建模问题。该方法能有效刻画移动区域的动态时空特征。Aiming at the problems existing in the modeling of changes of spatio-temporal relations between moving regions in two-dimensional Euclidean space,this paper proposed a change sequence model of spatio-temporal relations,and established the conceptual neighbourhood of spatio-temporal relations changes.This strategy presented a way of analyzing the topology,distance and orientation relations between moving regions changing with time based on the spatio-temporal model upon time slice to deal with the problem of integrated modeling of changes of spatio-temporal relations.This method could effectively characterize the dynamic spatio-temporal characteristics of the moving regions.
