摘　　要：以上海老城厢为对象,通过设计实验探讨街区内部的巷弄体系——毛细血管——在旧城改造中对于风貌保护与传承的价值与潜力。选取不同时空语境下的2轮毕业设计成果,从形态学、类型学视角分析6个设计案例中对待内部巷弄体系的立场与设计策略,论证和总结不同策略对城市空间的影响,阐明保护巷弄的类型学特质是以毛细血管为线索的城市设计策略的关键。实验显示:保持巷弄的结构、形态、层级和空间尺度至关重要,在此基础上建筑的类型可以多样;建筑与巷弄达成紧密的空间关系是设计操作的核心。Through the case of the old Shanghai town,this research discusses the value and potential of“capillary”,the lane system within the urban blocks for the preservation and inheritance in the transformation of old city.Based on six cases from two rounds of diploma projects with different conditions,it analyzes the standpoint and design strategy to deal with the internal lanes system from a morphological and typological view,and discusses the influences of different strategies on the urban space.It clarifies that the protection of typological characteristics of the lane system is crucial for urban design strategies with the clue of“capillary”.The experiment shows that it is highly important to keep the structure,form,hierarchy and spatial scale of lanes.Based on this,the building types can be various,and it is the core to have a balance between the lanes and buildings in the design operation.
