黄山松单木材种出材率表的编制

Formation of seed yield rate table of Pinustaiwanensis single wood species

选用4个削度方程,利用样木数据,通过求解方程参数,得到4个方程的拟合精度和效果,利用TOPSIS分析法得到了最优削度方程,建立了黄山松带、去皮胸径关系式及树皮率方程,编制了黄山松二元单木、一元单木材种出材率.

Using 4 taper equations and datum of sample tree and working out the equation parameters, the paper got the fitting precision and effect of 4 equations. On this basis, the paper obtained the optimal taper equation and built the relation of diameter with Bark and peeled diameter and bark rate equation as well.
