摘要
对日本落叶松三测树因子采用了5个经验方程和灰色GM(1,1)模型进行研究,经验方程中选中了柯列尔式,柯列尔式的各测树因子的残差平方和均小于GM(1,1)的残差平方和.
Three tree factors of diameter at breast height, tree height and tree volume of Japanese larch had been studied by using 5 empirical formulas and grey GM(1,1) model in this paper. Corial formula was much better for its Residual Sum of Squares of tree factors were less than those of GM (1,1) model.
