Beijing Enterprises Water Group (China) Investment Limited, Beijing 100102, China）Abstract： Based on the study of the carbon sequestration capacity of the urban green space in 7 cases in North China, asystematic calculation method was proposed. The results showed that the carbon sequestration capacity per unit area of urban greenspace for Xiong'an New District was approximately 2.62 kg/a·m2. The carbon sequestration capacity of each vegetation communitywas in the descending order with arbor (2.66 kg/a·m2), shrub (2.59 kg/a·m2), and ground cover (2.01 kg/a·m2). The research resultswill provide a scientific basis for realizing the rational layout of the urban green space and promoting the construction of the low-carbon cities.Keywords： Urban Green Space；Carbon Sequestration Capacity；Xiong'an New District；Vegetation；Carbon SinkCLC number： X24 城市作为人类生产和生活的中心，容纳了当前世界过半的人口，导致城市人均能耗是农村地区的3.5 倍，超过 75% 的温室气体是从城市中产生...
