摘　　要：通过对福建三明莘口教学林场28年生香叶树人工林生物量与生产力及其生长过程的研究,结果表明:28年生香叶树人工林平均树高、胸径和林分蓄积量分别为16.9m、17.8cm和421.484m3.hm-2,林分生物量和乔木层生物量则分别达310.58和303.67t.hm-2,乔木层生物量所占比例大小顺序为:干(63.47%)>根(17.86%)>枝(14.41%)>叶(4.25%);活枝和叶主要分布在12m以上;与杉木相比,香叶树与同龄杉木生长过程有所不同,前期生长较慢,中期变化强烈,后期较为平稳,成熟龄较长.Biomass, productivity and growth processes of a 28-year-old Lindera communis plantation were studied in Sanming, Fujian, China.The results showed that average tree height, average diameter at breast height (DBH) and growing stock were 16.9 m, 17.8 cm and 421.484 m^3·hm~\{-2\}, respectively, for the L. communis plantation.The stand biomass and arbor layer biomass of the plantation were 310.58 and 303.67 t·hm~\{-2\}, respectively. The proportion in biomass of different components in arbor layer were in the order of stem(63.47%)>root(17.86%)>branch(14.41%)>leaf(4.25%).Living branch and leaves mainly grew over height of 12 meters. L. communis grew slowly at the early stage, fluctuating at middle age stage and stabilizing at later stage, and thus had a longer time for maturity compared with Chinese fir.
