摘　　要：为研究乔木生长发育过程中温室气体排放等对城市环境造成的负面影响,本研究以芜湖市金桂树(Osmanthus fragrans var.thunbergii)为对象,运用混合生命周期评价技术核算其生命周期各阶段中的碳足迹。结果显示:CO 2是乔木生命周期排放的主要温室气体,占比达98.5%。随着日常管理维护频率的增强,碳足迹不断升高。机械燃油是直接碳排放的主要贡献者。外界经济系统的物质能源投入造成的间接温室气体排放比直接排放高出53.14%。本研究结果将为城市金桂树的管理方式提供决策支持,并为日后同类树种的管理提供数据与理论参考。In order to study the negative effects of greenhouse gas emissions on urban environment during the growth and development of trees,the carbon footprint of the Osmanthus fragrans var.thunbergii in Wuhu was calculated by using the hybrid life cycle assessment technology.The results showed that as the frequency of maintenance increases,the carbon footprint continues to rise.CO2 is the main greenhouse gas emitted in the life cycle of trees,accounting for 98.5%.Mechanical fuel is the major contributor to direct carbon emissions.Indirect greenhouse gas emissions caused by material and energy input in the external economic system are 53.14%higher than direct emissions.The results of this study will provide decision-making support for the management mode of Osmanthus fragrans var.thunbergii,and provide data and theoretical reference for the management of similar species in the future.
