摘　　要：目前在全球范围内,应对气候变化已经成为各国的核心议题之一,多个国家和地区提出了碳中和目标。城市气候环境变化与城市碳储量和碳汇能力直接相关,“双碳”目标也影响着未来人居环境的建设与发展。首先,基于高清卫星遥感影像反演推导,通过估算公式获得北京中心城区碳储量数值,形成中心城区现状碳汇能力初步评价。其次,以130个街道辖区单元为研究单元,对街区尺度碳汇能力进行评级。结合北京中心城区38个气象站的气象数据指标,展开碳储量、气候环境指标和植被指数之间的耦合性关系分析,定量研究植被对于碳汇能力提升和气候环境改善的影响。最后,从街区尺度视角,有针对性地提出提升碳汇能力和改善气候环境的相关策略——提高街区植被覆盖度、增加三维绿量和提高植被养护水平。Tackling climate change has now become one of the core issues of countries around the world,and several countries and regions have proposed carbon neutrality goals.Urban climate and environment changes are directly related to urban carbon storage and carbon sink capacity,and carbon peaking and carbon neutrality goals also affect the construction and development of human living environment in the future.Based on the inverse derivation of high-definition satellite remote sensing images,this research obtains the carbon storage value in the central urban area of Beijing through an estimation formula,based on which achieves a preliminary evaluation of the current carbon sink capacity thereof.Additionally,it selects 130 sub-district areas as research units to grade carbon sink capacity at the block scale and,in combination with the meteorological data indicators of 38 meteorological stations in the central urban area of Beijing,further analyzes the coupling relationship between carbon storage,climate environment indicator and vegetation index for a quantitative study of the impact of vegetation on the improvement of carbon sink capacity and climate environment.Finally,it puts forward pertinent strategies to improve carbon storage capacity and climate environment in the view of block scale,namely expanding block vegetation coverage,increasing 3D green quantity and improving vegetation conservation level.
