广东省杉木树种二元立木材积可变参数模型研究

采用155株建模样本,利用现代建模理论和方法,以山本式固定参数模型和可变参数模型建立了广东省杉木树种的二元立木材积模型。模型自检及64株检验样木验证表明,固定参数模型和可变参数模型精度均符合建模要求,能满足生产需要,但后者具有更优的适用性能。

The Establishment of the Standard Volume Models for Chinese Fir in Guangdong

In this paper,the standard volume models with fixed parameter equation and variable parameters equation of Chinese fir have been established by applying modem modeling theory,with 155 trees being sampled for the modeling.The result tested by itself and 64 tested sampled trees have showed that the precision of the two models based on the fixed parameters and the variable parameters are so high that they can be applied in practice.Furthermore,the variable is more effective than the fixed.
