城市三维网络模型是针对当代城市所面临的空间需求与环境容量,局部空间与整体空间等矛盾,以高密度城市或城市高密度地段为对象的关于城市内部空间结构模式的初步探索。城市空间的效益是其基本的着眼点。本文从层次和结构等方面阐述了城市三维网络模型的基本建构,并讨论了其演进和发展的趋势。 The urban three-dimensional network model is aiming at the contradiction between the space demand and the environmental capacity, the local space and the overall space confronting the contemporary cities, and the initial exploration of the urban interior spatial structure pattern in high-density cities or high-density urban areas. The benefits of urban space is its basic focus. This paper elaborates the basic construction of urban three-dimensional network model from the aspects of hierarchy and structure, and discusses its evolution and development trend.
