| 摘 要： | 采用模型分析法研究了雁北地区樟子松的地径(D0)、胸径(D)、树高(H)、枝下高(h)、冠幅(cr)因子与各器官生物量、总生物量的相关关系。结果表明,樟子松各器官及总生物量最优模型为:总生物量ln Wat=-1.65+0.78 ln(D2H);树干生物量ln Wt=-1.15+0.91ln(D2H);树冠生物量ln Wcr=1.24+0.16D;树枝生物量ln Wb=-1.93+1.83 ln D;树叶生物量ln Wl=-1.36+1.28 ln D.

| Abstract: | The correlation between total biomass and organ biomass and diameter at ground （Do）, diameter at breast （D）, height （//）, under branch height （h） and canopy diameter （cr） of Pinus sylvestris in Yanbei area were studied using model analysis. Results showed that the optimal regression models of organ and total biomass were as follows, total biomass lnWat = - 1.65 ＋0. 78 ln（D^2H）, truck biomass lnWt = - 1.15 ＋0. 911n （D^2H）, canopy biomass lnWcr = 1.24 ＋0. 16D, branch biomass lnWb = - 1.93 ＋ 1.83 lnD, leaf biomass lnW1 = - 1.36 ＋ 1.28 InD. |
