摘　　要：对26年生楠木人工林和杉木人工林的乔木层+林下植被层C储量及其分配进行了研究,结果表明:楠木林乔木层C储量为61.7 t.hm-2,小于杉木林乔木层C储量(72.7 t.hm-2);而楠木林林下植被层C储量为1.5 t.hm-2,大于杉木林林下植被层C储量(1.0 t.hm-2)。楠木干材的C储量较小,仅为杉木干材C储量的71.1%;但26年生楠木人工林尚未达到蓄积生长的数量成熟阶段,因此仍具有较高的固C潜力。Carbon storage and component for the tree layer and undergrowth were compared between two 26-year-old plantations of broad-leaved species,Phobe bournei,and conifer species,Cunninghamia lanceolata（Chinese Fir）,in Youxi, Fujian Province.The results showed carbon storage of tree layer was 61.7 t·hm^-2 for Phobe bournei,which was lower than that of Cunninghamia lanceolata（72.7 t·hm^-2）;but the carbon storage of undergrowth was 1.5 t·hm^-2 for Phobe bournei,which was higher than that of Cunninghamia lanceolata（1.0 t·hm^-2）.The carbon storage in Phobe bournei plantation accounted for 71.1% of Cunninghamia lanceolata plantation.However,stock volume of 26-year-old Phobe bournei plantation was still in a period of fast growth,high potential of carbon storage could be expected thereafter.
