摘　　要：根据7块不同林龄杉木人工林标准地调查的数据,对亚热带杉木人工林生物量和碳储量及其垂直分布进行研究。结果表明:杉木人工林林木和各器官生物量随着林龄的增大而增加,树干所占比重最大且逐渐增大,在林龄28年时,乔木层的生物量最大为167.86 t/hm2。杉木人工林碳储量垂直分布序列为乔木层>凋落物层>草本层,分别为50.28 t/hm2、4.32 t/hm2、1.50 t/hm2,平均年固碳量分别为2.44 t/hm2·a-1、0.19 t/hm2·a-1、0.14 t/hm2·a-1。杉木人工林总平均生物量、总平均碳储量和总平均年固碳量分别为119.05 t/hm2、56.10 t/hm2、2.77 t/hm2·a-1。因此,乔木层作为森林生态系统中主要的碳库层,对于森林的碳汇功能发挥着重要的作用。Based on the data of 7 permanent plots, the storage and spatial distribution of carbon and biomass in Chinese fir plantations were researched in Jiangle County of Fujian Province. The results show that biomass of both arbor layer and organs increased significantly with the increasing of stand age, the tree trunk biomass occupied the largest share of whole tree and gradually increased, and when the stand age reached 28-year-old, the max biomass of arbor layer was 167.86t/hm^2; The carbon storages of arbor, understory layers and litter in vertical distribution ranked from big to small as follows： arbor 〉 litter 〉 understory layers, they values were 50.28 t/hm^2, 4.32 t/hm^2, 1.50 t/hm^2 respectively, their annual carbon storages of arbor, understory layers and litter were 2.44 t/hm^2·a^-1, 0.19, and 0.14 t/hm^2·a^-1, the average biomass, average carbon storage and annual carbon storage of total Chinese fir plantations were 119.05 t/hm^2, 56.10 t/hm^2, 2.77 t/（hm^2·a）. Obviously, the arbor layer as a major carbon stock of forest ecosystem plays an important role for collecting carbon.
