当下，城市规划的精细化趋势正在改变我们对空间实践的理解，不仅包括物理现实的营造，还涉及建成环境的运营和更新，以及使用者对空间的再创造。对此，规划研究应提供处理繁杂信息、协调异质行动者的理论工具。然而现有的组装思想善于描述现实集合的变化，缺乏对变化具体来源的理论和方法进行再现、分析和评判。为填补这一空白，本文重温了德勒兹关于“潜在”的本体论，作为变化来源的解释，并引入“边界空间”的概念和图绘方法，以作为规划学科的分析工具；此外，以北京旧城旧鼓楼社区为例，追踪了“疏解整治促提升”行动前后物质空间、居民行动、个体记忆以及更广泛的城市历史的互动。通过一系列图绘，研究发现：边界空间潜在网络与现实集合节点具有趋于一致的作用特征，可以提醒规划工作者在城市更新实践中顺应这种作用力。

The refinement of urban planning has posed new challenges to contemporary spatial practices beyond the construction of material spaces, requiring the management of complex information and the mediation between heterogeneous actors and their re-creation of space through use. Urban research is being challenged to provide appropriate theoretical tools. While mainstream assemblage thinking effectively describes how actual assemblages change, it lacks methodologies for representing, analysing and evaluating the concrete genesis of change. To fill this gap, this paper revisits Deleuze’s concept of “the virtual” as the ontological source of change and introduces the notion of “boundary space” as an analytical tool for urban planning. Taking the Jiugulou neighbourhood of Beijing Old City as an example, the study traces the changes in the material spaces, residents’ activities, individual memories and the broader urban history before and after the “Relocation, Remediation and Improvement” initiative. Through a series of maps, we discover that boundary space tends to maintain the consistency of the nodes of virtual networks and actual assemblages of a particular urban site. This paper reminds practitioners of urban regeneration to heed this natural force of boundary space.
