摘　　要：[目的]研究吊皮锥人工林的碳贮量情况。[方法]以广西国有维都林场27年生吊皮锥人工林为研究对象,采用标准木法、样方收获等方法对其碳贮量的分布情况进行研究。[结果]27年生吊皮锥人工林碳贮量丰富,林分的碳贮量为340.25 t/hm^(2),乔木层、灌木层、草本层、凋落物层和土壤层的碳贮量分别为128.21、0.11、0.18、3.76和207.99 t/hm^(2)。乔木层占植被层碳贮量的比例最大,为96.94%,其中吊皮锥地上、地下2部分碳贮量分别占76.02%和20.91%。[结论]吊皮锥人工林的碳贮量较为丰富,可作为较好的碳汇树种来发展。[Objective]To study the carbon storage of Castanopsis kawakamii plantation.[Method]The distribution of carbon storage of 27-years-old Castanopsis kawakamii plantation in Weidu forest farm of Guangxi Province was studied by standard tree method and quadrat harvest method.[Result]The carbon storage of 27-years-old Castanopsis kawakamii plantation was rich,the carbon storage of stand was 340.25 t/hm^(2),the carbon storage of tree layer,shrub layer,herb layer,litter layer and soil layer were 128.21,0.11,0.18,3.76 and 207.99 t/hm^(2)respectively.The tree layer accounted for the largest proportion of carbon storage in the vegetation layer,accounting for 96.94%,of which the aboveground and underground carbon storage of the cone accounted for 76.02%and 20.91%respectively.[Conclusion]The carbon storage of Castanopsis kawakamii plantation is rich and can be used as a better carbon sink tree species.
