摘  要:
通过对甘肃省白龙江林区沙滩林场的22块云杉人工林标准地进行调查研究,以胸径、树高、D2H分别为自变量拟合建立云杉人工林树干、树冠及地上部分生物量模型。通过假设检验,所拟合的生物量具有统计学意义,方程为W树干=0.146 D2.065,W树冠=0.029 D2.431,W地上=0.155 D2.214。

摘  要:
Through the investigation on 22 sample plots of Picea asperata plantation in the beach forest farm of Bailongjiang forestry region,this paper fits and establishes a biomass model of tree trunk,tree canopy and above-ground vegetation with diameter,tree height and D2 H as independent variables respectively. By hypothesis test,the fitted biomass has statistical significance,and the equations were Wtrunk= 0. 146 D2. 065,Wcanopy= 0. 029 D2. 431,Wabove-ground= 0. 155D2. 214.
