摘　　要：杨树是河南省乔木林蓄积占比最高的树种,为了准确估算河南省杨树的生物量需要建立适用的生物量模型。研究以39株杨树生物量调查数据建立了5个以胸径为自变量的一元生物量模型和2个以胸径和树高为自变量的二元生物量模型,并对模型的拟合精度进行了分析,筛选出最优一元和二元生物量模型。Poplar is the tree species with the highest proportion of tree volume in Henan Province.It is necessary to establish a biomass model suitably for the poplar in Henan Province for accurately counting the biomass.In this study,five univariate biomass models and two bivariate biomass models were built based on 39 poplar trees.The accuracy of the models was analyzed,and the optimal univariate and bivariate biomass models were screened out.
