摘要： 交通规划在空间规划体系框架下需要厘清空间结构与网络结构间的适配关系，基于OD的传 统交通分析理论很难适应空间规划体系框架下的空间构造分析。基于流空间理论的“以流定形”设 想，通过挖掘网络关系下的流动要素，以网络和流诠释空间要素间的关系，形成支撑城市发展的空 间交互模型基础。在“以流定形”的研究范式下，提出以空间活动系统研究替代网络交通流分析， 并遵循空间中的关系-空间中的活动-空间中的网络的逻辑对相关问题进行探讨。

Abstract： Since transportation planning involves the spatial framework it is necessary to clarify the adaptive relationship between space layout and network structure in transportation planning. However the ODbased traditional transportation analysis theories can hardly be applied to the spatial analysis under the framework of spatial planning system. Based on the concept of “shaped by flow”, this paper develops the spatial interaction model of urban development through discussing the spatial elements relationship between network and flow. Under the research pattern of “shaped by flow”, the paper proposes to replace the analysis of network transportation flow with the spatial activity systems, and follow the logic of the relationship between activities' space and network space to discuss relevant issues.
