摘　　要：针对三维地理信息系统中的三维空间数据模型,结合城市规划工作,分析讨论了三维数据模型集成的必要性以及TIN与CSG、八叉树与TEN、矢量与栅格等混合数据模型实现的方法和思路,提出了在城市规划应用中模型集成的适用类型及有关要求。Based on many superiority of GIS and its wide application foreground in city planning domain, and investigation of other people, combining city planning, we analyze and discuss the necessity of integration of 3D data model and the method and thinking of realizing hybrid data model for 3D data model of 3D GIS such as TIN and CSG, Octree and TEN, vector and grid, and so on. Some suitable kinds of model integration and some requirements in application of urban planning are put forward.
