摘要
2016年,通过样地调查与解析木分析,对莲都林场1979年引种的日本扁柏Chamaecyparis obtusa、日本花柏C.pisifera和日本香柏Thuja standishii的生长特征及其地上生物量进行了测定。结果表明,3种柏树胸径速生期在10～15年生期间,树高速生期在5～10年生时,单株材积年生长自30年生后趋于平稳;日本扁柏、日本花柏和日本香柏单株地上生物量分别为89.56 kg,62.57 kg和68.78 kg,其林分地上生物量分别为159.86 t·hm^(-2),138.91t·hm^(-2)和212.74 t·hm^(-2)。
Investigations were carried out in2016in Liandu Forest Farm of Zhejiang province on growth traits and aboveground biomass by sample plots and analytic wood of Chamaecyparis obtusa,C.pisifera and Thuja stardishii introduced in1979by cuttings.The results showed that fast growth period of DBH of three determined species was between10-year and15-year and that of height was between5-year and10-year.The individual tree volume increment was gradually stable after30-year.Above ground biomass of individual tree of tested species were89.56kg,62.57kg and68.78kg respectively,and that of stands were159.86t/ha,138.91t/ha and212.74t/ha respectively.
