From the perspective of city-transport system, this article applies space syntax to analyze the physical integration of cities. Traditionally, space syntax is mainly applied to urban areas, buildings, and other scales. However, when space syntax is applied to the configuration analysis of urban agglomeration, the change of scale causes changes in spatial perception and human behavioral patterns. Thus, we present a new method of space syntax. This method defines the lane and track between entrance and exit, and city as node, which represents small-scale space. Infrastructure, such as stations, entrances, and exits, are defined as links. The urban agglomeration is thus transformed into a topological network, and then displayed as a bipartite graph of cities and routes. We take the urban agglomerations in the Yangtze River Middle Reaches (YRMR) as the case study area and analyze its spatial configuration from the perspectives of local and integral, interfaces at different scales, gaps, evolution of the dual foreground and background networks, and evolution of the transport networks. The results reveal the way cities integrate with each other and further reveal the multi-scale spatial structure of urban agglomeration.

本文从城市-交通系统的角度，运用空间句法分析城市的物理融合。传统上，空间句法主要应用于城市区域、建筑等尺度。然而，当空间句法应用于城市群的配置分析时，尺度的变化会引起空间感知和人类行为模式的变化。因此，我们提出了一种新的空间句法方法。该方法定义了入口和出口之间的车道和轨道，城市为节点，代表小尺度空间。基础设施，如车站、入口和出口，被定义为链接。城市群由此转化为拓扑网络，然后显示为城市和路线的二部图。我们以长江中游城市群（YRMR）为案例研究区，从局部和整体、不同尺度的界面、缺口、双前景和背景网络的演化以及演化的角度分析其空间配置。的运输网络。研究结果揭示了城市相互融合的方式，进一步揭示了城市群的多尺度空间结构。
