作为城市更新的触媒，城市轨道交通的建设为存量地区交通站域城市空间的增效提质提供了重要机遇，也为城市存量发展带来新的动力。本文以传统“节点-场所”模型为基础，纳入轨道交通站域的“品质”感知维度，构建 “节点-场所-品质”三维魔方状态分析模型，探究在三维价值交互下存量地区轨道交通站域的更新潜力。以天津市中心城区内环地区为实证，研究结果显示：依赖型和失衡型站域分别占比高达35.49%和38.71%，平衡型和协调型则分别占比22.58%和3.22%；更新潜力较高的站域则集中分布在内环边缘地区，并且在建地铁站域的更新潜力也相对较高，而低更新潜力地区则集中分布于中心商务区。上述发现为大都市存量地区轨道交通站域的城市更新提供了理论支持和政策启示。

As a catalyst for urban renewal, the construction of urban rail transit provides important opportunities for improving the quality of urban space of transit station area in the downtown, and also brings new impetus to the inventory development. By incorporating the "Quality" dimension into the traditional "Node-Place" model to indicate the perception of spatial environment, this paper constructs the “Node-Place-Quality” Rubik's Cube state model, which aims to assess the renewal potentials of transit station areas in the downtown. By taking the central area of Tianjin as case study, the modeling results show that the proportion of dependent and imbalanced types of transit station area is as high as 35.49% and 38.71%, respectively, while balanced and coordinated types account for 22.58% and 3.22%, respectively; The transit station areas with high renewal potential are concentrated in the edge of the Inner Ring of Tianjin, and the renewal potential of transit station under construction is also relatively high, while the transit station areas with low renewal potential are agglomerated in the central business district (CBD). These findings provide theoretical support and policy insights for the urban renewal in the transit station area in the metropolitan`s downtown.
