The centralized development of urban space is beneficial for improving urban efficiency, while decentralized development is beneficial for improving the ecological quality of cities. On the basis of the traditional high-intensity development TOD model at the station, this article reconstructs the existing urban spatial structure through a hierarchical rail transit network system, enabling areas outside the station to achieve low-density and high-quality ecological development. To achieve this new structural process of urban space, this article reveals the basic characteristics of the TOD model from the perspective of flow patterns, analyzes its driving and implementation mechanisms, and proposes urban space development strategies and ecological spaces under this model.
