【摘要】 在森林调查中树皮因子是指树木的去皮直径与带皮直径的商。通过树皮因子可以利用带皮树干材积估算去皮材积,可以评估木材加工过程树皮残余量,可以预估树皮厚度,基于树皮厚度求算材种出材量等。树皮因子变化规律可以为实际生产提供理论支持,从而更好地进行木材生产和森林经营。研究树皮厚度和树皮系数的变化规律从而揭示树皮的变化规律,对提高林分蓄积生长量的精度有着重要的现实意义。更多还原

【Abstract】 In forest investigation,the bark factor refers to the quotient of the peeled diameter and the skin diameter of the tree. The bark factor can be used to estimate the volume of barked timber,the residual amount of bark,the thickness of bark,and the output of wood species. The change rule of bark factor can provide theoretical support for actual production,so as to better carry out timber production and forest management. Studying the bark thickness and bark coefficient to reveal the change rule of bark is of great practical significance for improving the accuracy of stand volume.更多还原
