南京科巷片区曾经是一种合理、宜居的城市公共空间形态，然而随着外部社会环境条件的变化尤其是 2020 年新型冠状病毒肺炎疫情的冲击，使得科巷产生许多问题与矛盾，并在特殊时期产生了健康管理风险。选取南京科巷片区 6 条街巷空间为研究对象，从街巷空间体系、文化体系以及使用人群 3 个角度进行调研分析，梳理现状存在的问题，从健康生活的视角提出科巷改造的城市微更新设计策略：1）街巷空间的集约化利用；2）街道家具延续街巷文化；3）构建智慧生态化健康生活体系。

However, with the changes of external social environment, especially the impact of the 2020 Covid-19 epidemic, many problems and contradictions were created in alleys, and the risk of health management was generated in special times. This paper selects six streets and alleys in Kexiang District of Nanjing as the research object, conducts research and analysis from three perspectives of street space system, cultural system and users. By combing the existing problems, the paper puts forward the design strategies of urban smallscale regeneration from the perspective of healthy life: the intensive utilization of street space, the continuation of street furniture to street culture, and the construction of a intelligent and ecological healthy life system.
