摘要
通过对28年生香叶树与杉木人工林生长和生物量测定,进行香叶树和杉木人工林生产力的比较研究,结果表明:香叶树是一种生长迅速的阔叶树种,其人工林蓄积量为421.88 m3/hm2,比杉木人工林高7.09%;香叶树人工林分生物量为305.43 t/hm2,是杉木人工林的1.59倍,其生物量乔木层是杉木林的1.68倍。
Base on the investigation of stand growth,biomass,structure and productivity, the biomass productivityies of 25-year-old Lindera communis plantation and of Cunninghamia lanceolata Plantation were compared. The results were showed as following ： The stand volume of Lindera communis plantation was 421.88m^3/hm^2, increased by 7.09% compared with that of Cunninghamia lanceolata plantation. The stand total biomass of Lindera communis plantation was 305.43t/hm^2, 1.59 times as much as that of Cunninghamia lanceolata; plantation. It proves Lindera communis is a fast-rowing tree species.
