割裂与融合：日常生活视角下基于人群 活动的济南老城区公共空间异化与互融 更新研究

以当代老城区改造过程出现的隔离现象为切入点，从日常生活的视角出发，选取济南老城区具有公共空间异化特征的曲水亭片区作为观察和研究对象，运用以PSPL调研法、动线观察法为核心的多目标导向的人群活动综合调研方法，通过定性与定量相结合的方式解译老城区公共空间中存在的割裂现象和异化表征，并以其中4个典型的街道界面进行“空间-行为”模式的对比分析，总结出“流动型、闭环型、单层隔离型、双层隔离型”4类公共空间异化模式，从而更深层次地揭示公共空间异化产生的动因和机制。最后，在当代存量更新的语境下，基于日常生活与物质空间的动态关联，探讨走向社区融合的老城区公共空间互融更新策略，以期为老城区的活化利用和可持续发展提供途径。
