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。
Through the investigation on 22 sample plots of Picea asperata plantation in the beach forest farm of Bail- ongjiang forestry region, this paper fits and establishes a biomass model of tree trunk, tree canopy and above-ground vege- tation with diameter, tree height and D2H as independent variables respectively. By hypothesis test, the fitted biomass has statistical significance, and the equations were Wtrunk = 0. 146 D2.0o65, Wcanopy = 0. 029 D2. 431, Wabove-ground=0. 155 D2.214
