摘　　要：为了减少时态地理信息系统的数据冗余、提高运行效率,该文在对比分析多种时空数据基态修正模型的基础上,选择了一种只存储几个基态和相应变化信息的多基态修正模型,并以德州市某地区为例进行三维时空数据组织,实现了城市变化的三维动态展现,达到了城市变化三维时空可视化表达的目的。In order to reduce the data redundancy and improve the performance efficiency of TGIS,the paper presented a multi-base state amendment model that stores several base states and corresponding change information,based on the comparative analysis on a variety of base state amendment models.Finally,Dezhou City was taken as an example to realize the 3Ddynamic display,and the result could achieve the 3Dspace-time visualization expression for urban development.
