摘要以上海市某街道为例，从城市构成要素的微观角度对街道空间进行分析和解读，提出了研究城市网络空间系统的策略。在方法论层面，本研究运用空间理论的相关研究方法，探讨了城市要素、要素空间及其空间网络系统的构建过程。分析内容包括集成度及其分布（总体入渗特征）、系统化程度和局部典型区的调整关系图。分析得出三个结论：从要素上看，田子坊街道空间呈不同尺度的环形连接，并平行连接，形成整体空间结构。在全球层面上，整合度的分布呈现出从街道到内部的点状渗透模式，具有局部核心。在局部和全局相关性方面，具有较高交通属性的空间倾向于增加局部和全局的整合，具有较强功能属性的空间倾向于增加局部与整体的分离。建筑的单元空间及其相关的浅层空间近似于整体协同度。
ABSTRACT Using a street in Shanghai as a case study, a strategy was developed to study an urban network space system by analyzing and interpreting street space from the microscopic perspective of urban composition elements. At the methodological level, this study, using research methods related to Space Syntax Theory, explored the process of establishing urban elements, element space, and a spatial network system for these elements. The analysis included the integration degree and its distribution (overall infiltration characteristics), the systematic degree, and an adjustment relationship graph for local typical areas. There are three conclusions drawn from the analysis: From the perspective of elements, the Tianzifang street space is annularly connected in circles on different scales and connected in parallel to form an overall spatial structure. At the global level, the distribution of integration degrees exhibits a dotted infiltration pattern from the street to the interior, with a local core. In terms of local and global correlations, spaces with higher traffic attributes tend to increase local and global integration, and spaces with stronger functional attributes tend to increase the separation of local from whole. The element space and its associated shallow space of buildings approximate the overall synergy degree.
