摘要：通过对广西大青山实验林场12年生杉木(Cunninghamia lanceolata)人工林的生长量、生物量和生产力进行研究,结果表明:12年生杉木人工林平均胸径、平均树高和蓄积年均生长量分别为13.7 cm、11.8 m、18.6 m3/hm2;林分生物量和净生产量分别为92.502 t/hm2、9.763 t/(hm2.a),其中,乔木层的生物量及净生产量分别占林分总量的96.06%和93.78%,灌木层和草本层的生物量及净生产量依次占林分总量的0.97%、2.98%、1.59%、4.63%。由于该实验区位于两山夹一沟,气候湿润,水热条件很适宜杉木的生长,所以生产力水平较高。
Growth increment, biomass and productivity of a 12-year-old Cunninghamia Lanceolata plantation were studied in Daqingshan Trial Forest Farm of Guangxi. The results showed that the mean DBH, mean tree height and the annual average growth increment in 12-year-old Cunninghamia Lanceolata plantation were 13.7cm, 11.8 m, and 18.6 m^3/hm^2, respectively; the biomass and net production of stand were 92.502 t/hm^2 and 9. 763 t/ （hm^2.a） , respectively; among which, tree layer biomass and net production accounted for 96.06 % and 93.78 % respectively of the total biomass; the shrub and herb layer biomass and their corresponding net productionaccounted for 0.97 % , 2.98 % and 1.59 %, 4.63 % respectively of the total biomass. As the trial was located in a valley sandwiched with mountains on both sides, its climate was humid, and water and heat condition was suitable for the growth of Chinese fir, which made high productivity possible.
