为了估测单位面积及全林可利用树皮量,给生产与管理提供可靠依据,特对柠檬桉树皮率进行了研究。树皮率与胸径有着密切的关系,仅通过胸径去研究树皮率的经验公式。本文主要取用雷州林业局1973年编制立木材积表的样木资料,采用典型选样,以2米区分段取皮实测。获得13组499株(4—30径阶)样木(其中9株22—30径阶的样木是[83年]
In order to estimate the unit area and the amount of available bark of the whole forest, it provided a reliable basis for the production and management, and studied the eucalyptus bark rate of lemon. The bark rate has a close relationship with the DBH, and the empirical formula of bark rate is only studied by the DBH. In this paper, we mainly use the sample data of timber established by Leizhou forestry bureau in 1973, adopt the typical sample selection, take 2 meters to take the peel test. Thirteen groups of 499 (4-30 diameter) samples of wood were obtained (9 samples of 22-30 diameter wood samples were [83 years]
