| 建设与保护城市绿地作为基于自然的解决方案（NbS）的重要策略之一，对减缓气候变化、实现“碳达峰”及“碳中和”具有积极的作用。从多尺度视角全面认识城市绿地碳汇功能，分析其实现途径及其机理，有利于实现城市绿地全生命周期固碳能力提升，助力城市“双碳”目标实现。从城市绿地斑块、城区绿地系统、市域生态空间3个尺度切入，剖析碳汇功能的实现途径及机理，总结各尺度促进绿地碳汇效应提升的关键途径。建议未来应开展城市绿地全生命周期碳汇功能评估框架研究；进行城市绿地碳汇与其他功能间权衡协同关系研究；探究城市绿地碳汇功能景观格局驱动机制。 |

| Abstract: |
| As a Nature-based Solution (NbS), the construction and protection of urban green spaces has a positive effect on the mitigation of climate change and the achievement of carbon peaking and carbon neutrality goals. Comprehensively understanding the carbon sink function of urban green space from a multi-scale perspective and analyzing the realization approach and mechanism can help to improve the carbon sequestration capacity of urban green space throughout the life cycle and achieve carbon peaking and carbon neutrality goals. Taking the three scales of urban green space patch, urban green space system, and urban ecological space as the entry points, this research analyzes the approach and mechanism of carbon sink function, and summarizes key approaches to improve the green space carbon sink effect at each scale. In the future, it is necessary to implement research on the evaluation framework of the carbon sink function of urban green space throughout the life cycle, to study the trade-off and synergistic between the carbon sink and other functions of urban green space, and to explore the driving mechanism for the landscape pattern of the carbon sink function of urban green space. |
