摘要
对福建省南平市安曹下35 a生楠木林碳库及分配进行研究.结果表明,楠木林碳库为172.138 t.hm-2,其中乔木层碳库占楠木林碳库的40.14%,矿质土壤层碳库占55.99%,而林下植被层、枯枝落叶层、粗木质残体3个分室碳库所占比例之和不超过5%.楠木林的干材(干+皮)碳库占乔木层碳库的71.14%,楠木林根系碳库占乔木层碳库21.93%,楠木林枝和叶碳库所占比例总和不超过5%.因此,楠木林碳库主要分配在乔木层和土壤层.
The carbon storage and its allocation of the Phoebe bournei plantations in Nanping of Fujian Province were studied. The total carbon storage in Phoebe bournei was 172. 138 t · hm^-2, of which the carbon storage of tree layer accounted for 40. 14% , and that of the mineral soil occupied 55.99%. The total carbon storage of the undergrowth, litter layer and coarse woody debris （CWD） occupied no more than 5%. In the allocation of tree carbon pool to various organs, stem and bark, root accounted for 71.14% and 21.93% , respectively. The carbon storage of litter occupied no more than 5%. In conclusion, the most of carbon storage was allocated in tree layer and mineral soil.
