摘　　要：“双碳”目标与城市更新行动在时空上高度耦合。城市绿地作为城市碳汇系统的重要组成部分,既是提升城市品质与生态效益的重要平台,又是从源头上提高城市整体碳汇水平的主要途径。本文以基于自然的解决方案为理论基础,通过文献综述与案例研究,分析城市绿地系统的结构、要素与功能关系及其生态过程对碳汇的贡献;揭示在城市绿地系统的全生命周期中,植被类型与群落结构对碳汇效能的影响;探究在微观、中观、宏观及地下、地面、地上等多尺度上,实现“绿、蓝、黄”碳汇融合功能的原理机制、设计策略及技术路径,同时强调绿地系统空间结构与维护管理策略的重要性,为推进碳中和导向下的城市更新行动提供理论支撑与实践范式。Carbon peaking and carbon neutrality goals and urban renewal actions exhibit high spatiotemporal coupling. As the core carrier of the carbon sink network, the urban green space system achieves multi-dimensional value coordination of human settlement environment improvement, ecological function optimization and biodiversity protection through the source regulation of spatial organization and functional configuration.This paper employed Nature-based Solutions(Nb S) as the theoretical framework, integrated multidisciplinary systems such as landscape ecology, urban climatology and soil microbiology, and analyzed the correlation mechanism of green space system structure, elements and functions and its carbon sink ecological process through literature review and comparative case studies.The study reveals the dynamic impact of vegetation type and community structure on carbon sink benefits throughout the life cycle, explores the principle mechanism, design strategy and technical path of realizing the integration of terrestrial(green vegetation), aquatic(blue water), and edaphic(yellow soil) carbon sink mechanisms at multiple scales such as micro, meso, macro, underground, ground and aboveground, and proposes spatial optimization strategies such as system modeling analysis, plant phenological cycle management and ecological and economic collaborative decision-making.An innovative multi-scale design paradigm for carbon sink systems has been established: in the spatial dimension, a vertical carbon sink system of underground root layer-surface vegetation layer-aerial canopy layer is formed, and a synergistic mechanism of green vegetation carbon sink, blue water carbon sink and yellow soil carbon sink is coordinated;in the temporal dimension, a full-cycle management and control process of carbon sink potential assessment in the planning stage, carbon sink capacity optimization in the design stage, carbon sink process implementation in the construction stage, and carbon sink efficiency monitoring in the operation and maintena
