摘　　要：基于福建省森林资源2020年度监测数据,测算厦门城市森林碳储量和碳固定量,定量评估厦门城市森林碳汇抵消城市能源碳排放效果。结果表明:厦门城市森林总碳储量为150.37万t,总固碳量为26.63万t·a^(-1),而厦门城市在2016—2020年间年均能源碳排放量为925.91万t,厦门城市森林总碳储量约占年均能源碳排放量的16.24%,城市森林碳固定量可抵消能源碳排放量的2.88%。厦门城市森林平均碳密度为32.46 t·hm^(-2),平均固碳率为5.75 t·hm^(-2)·a^(-1),不同林型和林龄的碳密度和固碳率存在差异。依据厦门城市森林固碳量特征,从提升城市森林资源面积、优化城市森林空间结构以及强化科学经营管理等方面提出增加碳汇的相应策略,为城市森林科学管理提供支撑。Based on the annual monitoring data of forest resources in Fujian Province in 2020,the distribution characteristics of carbon storage and carbon fixation in Xiamen City were estimated,and the effect of Xiamen urban forest offsetting energy emissions was evaluated.The results showed that the carbon storage of urban forest in Xiamen was 150.37×10^(4) t.The carbon sequestration of urban forest in Xiamen was 26.63×104 t·a^(-1),from 2016 to 2020,the average annual energy carbon emission in Xiamen was 925.91×10^(4) t,and the urban forest carbon storage was about 16.24%of the average annual energy carbon emission.The urban forest carbon fixation can offset 2.88%of the average annual energy carbon emission.The average carbon density of urban forest was 32.46 t·hm^(-2) in Xiamen City and the average carbon sequestration rate was 5.75 t·hm^(-2)·a^(-1).Carbon density and carbon sequestration rate was different from forest type and forest age.Based on the characteristic of the carbon fixation in Xiamen City,the project put forward corresponding strategies to increase carbon sinks from the aspects of improving the area of urban forest resources,optimizing the spatial structure of urban forest and strengthening scientific management and operation,so as to provide support for the scientific management of urban forests.
