摘    要:该文以甘肃省小陇山锐齿栎林分为例,通过图形分析、相关分析和回归分析,结果表明:小陇山锐齿栎林分乔木层各组分生物量(W)与林分活立木蓄积量(V)、与林分平均胸径、平均树高和林分密度(2N)均存在极其显著的线性相关关系.采用代数和法,分2级控制,建立了林分乔木层各组分生物量(W)与林分活立木蓄积量(V)与林分平均胸径、平均树高和林分密度(2N)两种形式的生物量相容性线性模型,以95%的可靠性估计,两种形式的 模型对锐齿栎林分各组分生物量的预估精度均在98%以上. 

关 键 词:代数和    相容性线性模型    林分生物量    森林资源清查资料    锐齿栎    小陇山

Abstract:Graphic analysis,correlative analysis and regression analysis about Quercus aliena var.acuteserrata plantations in Xiaolong Mountains,Gansu Province were carried out.The results showed that there existed a prominent linear relationship between tree biomass composition(W) and growing stock volume(V) as well as the average trunk diameter,average tree height and stand density(~2N) of Q. aliena var.acuteserrata plantations in Xiaolong Mountains.Using algebraic sum method,the two linear models with compatibility between W and V as well as average trunk diameter,average tree height and stand density(~2N) were built from two layers.With 95% reliability estimates,the two models about the wood biomass of Q.aliena var.acuteserrata were over 98% precision in the preliminary estimates.
Keywords:algebraic sum method  linear model with compatibility  stand biomass  forest resources inventory data  Quercus aliena var  acuteserrata  Xiaolong Mountains
