摘要
本文针对云南松在东西河飞播林区的生长状况,分析其根颈(树基根涨尾部)径和胸径之间的关系,目的在于找出它们的关系变化,以便衡量当该树被盗伐、滥伐后被伐木的胸径大小,从而确定其材积量,为林政工作的顺利开展提供方便。经分析根颈径与胸径存在良好的线性关系。
Through observing the growth status of plane-sowed Yunnan pines along the East River and the West River,we have analyzed the relationship between their butt-end diameter and thorax diameters,and found out the changes in their relationships,which could indicate the thorax diameters of stoles and denudated pines,determining its volume and helping the adminis- tration of forestry.The analysis,has shown that butt-end diameter and thorax diameter have a perfect linear relationship.
