利用在南部广泛区域的采伐迹地上经整地营造的火炬松树干解析数据,建立了总材积和商品用材部分的材积方程。这里提出了用以预测注意高度式小头直径处的总材积和商品材部分的材积方程。树干的尖削度与商品材材积方程之间的关系使得对小头直径和树高的预测成为可能。
Using volumetric analysis of data from loblolly pine stems created by site preparation on deforested land in a wide area of the South, a volumetric equation was established for the total and commodity timber components. Here is a volumetric equation that is used to predict the total volume and the bulk of the merchandise at the diameter of the tip of attention. The relationship between the taper of the trunk and the product volume equation makes it possible to predict head diameter and height.
