Bark characteristics are not only used in the forest-wood supply chain, for example to calculate standing volumes, but also to transform wood volumes and masses. In this study, bark thickness, bark volume and bark mass were analyzed on the basis of 150 Scots pine discs, with a mean diameter of 13 cm. The mean double bark thickness was 3.02 mm, the mean bark volume proportion was 5.6% and mean bark mass proportion was 3.3%. Bark proportions were significantly affected by the log-specific variables ‘diameter over bark’, ‘proportion of bark damage’ and ‘double bark thickness’.

苏格兰松木工业木材的树皮比例

树皮特性不仅用于林木供应链中，例如用于计算站立量，而且还用于转换木材量和质量。在这项研究中，根据150根苏格兰松树圆盘（平均直径为13厘米）分析了树皮厚度，树皮体积和树皮质量。平均双树皮厚度为3.02mm，平均树皮体积比例为5.6％，平均树皮质量比例为3.3％。树皮比例受对数特定变量“直径大于树皮”，“树皮破坏比例”和“双树皮厚度”的影响。
