摘　　要：森林通过吸收大气中的二氧化碳固定到碳库中,在“双碳”目标中起着碳中和的重要作用。本研究基于大冶市2019年林业资源二类调查小班数据,采用材积源生物量法对大冶市森林资源的植被碳储量和碳密度进行测算,结果表明:大冶市现有森林植被碳储量114.36×10^(4)t,平均植被碳密度为23.66 t·hm^(-2);碳储量较高的区域主要集中分布在大冶南部山区,灌木林碳储量占比最高,其次为马尾松林;马尾松林的平均植被碳密度最高,达到35.64 t·hm^(-2)。该测算结果可为大冶市实现“双碳”目标以及森林资源的科学管理提供数据基础和决策依据。Forest plays an important role in the“carbon peak,carbon neutral”goal by absorbing carbon dioxide from the atmosphere and fixing it into the carbon pool.In this study,the vegetation carbon storage and carbon density of the forest resources in Daye City were calculated using the volumn to biomass method based on the forest resource inventory data in 2019.The results showed that the carbon storage of existing forest in Daye was 114.36×10^(4)t,and the average vegetation carbon density was 23.66 t·hm^(-2).The areas with higher carbon storage were mainly distributed in the southern mountain area of Daye,and the shrub forest had the highest carbon storage,followed by Pinus massoniana forest.The average vegetation carbon density of P.massoniana forest was the highest,reaching 35.64 t·hm^(-2).The measurement results can provide data basis and decision-making basis for the realization of the“carbon peak,carbon neutral”goal and the scientific management of forest resources in Daye City.
