| 摘 要： | 通过应用方程Ｖ＝αＤ＾ｂ和Ｖ＝αＤ＾ｂＨ＾ｃ拟合湿地松立木材积表模型，用对数线性化最小二乘法来实现最初的参数估计，并用改进单纯形法对模型参数组合进行优化，得到优化后的湿地松一元、二元立木材积模型：Ｖ１＝０．００００５２８４６Ｄ＾２．７７９８６７和Ｖ２＝０．００００５９３９８Ｄ＾２．１５９９６７Ｈ＾０．６６７８２７６，并利用此高精度的模型来编制湿地松的一元、二元立木材积表。

| Abstract: | By using the equations V=aD b and V=aD bH c and usual method for fitting those equations, the authors firstly linearized the parametres; then caculated the parameters by Least-square Method, one-way and two-way volume maths models of Pinus elliottii were worked out; then optimized them by Modified Simplex Method; they were established and described as : V 1 =0.000052846D 2.779867 and V 2 = 0.000259398 D 2.159967 H 0.6678276 . It suggested that the precision of volume tables of Pinus elliottii will be increased by application of Modified Simplex Method for further optimized models. |
