摘　　要：中国城市发展正在经历从粗放式的增量扩张转向精致式的存量品质提升,这一重大转型需要应对新时期城市发展的新目标和新要求.具有小规模、渐进式、高品质特征的有机更新成为遵循空间形态发展和城市运行逻辑的有效途径.本文提出并阐释了城市有机更新的三个重要维度——类型维度、层次维度和过程维度,并认为这是理解有机城市更新处理新旧关系、尺度关系和持续过程的关键.唯有在尊重城市发展规律及加深对有机更新维度理解的基础上,通过常态化“细胞层面”和“针灸式”的更新模式,城市的生命力才会更加旺盛、城市空间才会更有活力.In China,urban regeneration is undergoing a significant transformation,changing from extensive,massive urban renewal to intensive,elaborate regeneration.Facing challenges associated with new urban development objectives in geography,climate,biology,economics,and cultural aspects,small-scale,gradual,high-quality-oriented alive regeneration is proposed as an effective strategy to follow urban spatial development and operation logic.This paper emphasizes three vital dimensions in alive regeneration:typology dimension,layered dimension,and process dimension,as well as spatial improvement"at the cellular level"and"acupuncture style"to promote comprehensive and systematic urban development for vibrant and dynamic urban lives.
