摘　　要：对福建尤溪楠木(Phoebe bourmeiYang)幼龄林、中龄林和成熟林生态系统各组分含碳率和碳贮量进行了测定和比较研究.结果表明,不同发育阶段楠木林乔木层、林下植被层和凋落物层含碳率为42.64%—51.45%,表现为成熟林最大,中龄林次之,幼龄林最小,0—100 cm土壤层含碳率亦表现出同样的规律;随林龄增大,乔木层、凋落物层和土壤层碳贮量均逐渐增加,决定了生态系统总碳贮量也逐渐增大,成熟林生态系统碳贮量为210.32 t/hm2,分别是幼龄林和中龄林的1.67倍和1.26倍.Carbon content and carbon storage of Phoebe bourmei plantation of different growing stages were measured. The results show that the carbon content of the arbor trees, understory , litter and the soil for 100 cm depth is in the sequence of MP（mature-plantation） 〉 MAP （middle-aged plantation） 〉 MP（young plantation） ;the carbon storage of Phoebe bourmei plantation ecosystem increases with the age increment , which of MP is as much 1.67 times as that of YP, and as much 1.26 times as that of MAP, respectively.
