Abstract: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.
Keywords:Japanese larch  empirical formula  grey GM(1  1)model
