摘要
以黑龙江省带岭林业局大青川林场和永翠林场的兴安落叶松人工林为研究对象,基于41块样地调查数据和Richards模型,构建了含有林分变量的树高与胸径关系模型。利用混合效应模型方法拟合常规Richards模型yij=(β1+bi1)(1-e-(β2+bi2)xij)(β3+bi3)+εij和含有林分变量的模型yij=(β1+bi1)(Dq)(β2+bi2)(1-e-(β3+bi3)(N(β4+bi4))xij)+εij。结果表明:当对Richards混合效应模型拟合时,引入随机参数b1、b2时模型拟合最好;当对含有林分变量的Richards混合效应模型拟合时,引入随机参数b2、b4时模型拟合最好。模型检验表明:当随机抽取独立样本时,混合模型误差小于固定效应模型。如果随机抽取4个样本校正时,混合模型的误差和均方根误差降低71.8%和42.1%。
