摘要
用削度方程和单株带皮—去皮胸径的转换关系式两个模型对河南省杨树进行计算机理论造材,经精度检验,满足要求,方法可行,依此编制了河南省杨树材种出材率表。
The poplar in Henan Province is bucked theoretically with the taper equation and the converted equation between DBH outside bark and DBH inside bark.Tests of adaptabilityare made,and the results satisfy the request, so the method can be applied.Accordingly, merchantable volume tables are constructed.
