三维数字城市是目前GIS研究的热点问题之一，而城市三维空间数据能否得到有效组织和管理，直接决定三维数字城市建设的效果和质量。本文对城市三维空间数据的特征、数据管理技术以及存在问题进行逐一分析，并结合上海市三维空间信息的生产和管理经验，提出面向海量三维空间数据管理的策略，不仅为城市三维空间数据库建设中的关键技术问题提供了解决方案，也为三维空间数据在各领域更为广泛的应用奠定了基础。

The three-dimensional (3D) digital city is one of the current research foci of geographic information system (GIS) research. The features and quality of 3D digital city construction depend on the effective organization and management of 3D urban spatial data. This paper analyzes the features of both 3D spatial data and data storage technology, and identiifes and discusses existing problems in these ifelds. By examining the production and management of 3D spatial information in Shanghai, this paper presents possible strategies for facing the massive chal enges posed in the management of 3D spatial data. The proposed ideas offer potential solutions to key problems in the construction of 3D urban spatial databases, and also provide a strong foundation for further 3D GIS applications across a range of topic areas.
