在生产工作中,特别在测树制表工作中,往往要测定出树皮的厚度及其材积。对于这项工作,现在所采用的方法,是依一定的距离,在树干一侧或两侧,用斧砍开缺口后,量出皮厚,并据以求算出树皮材积。在大量生产和研究工作中,此项工作,需要极其大量的劳力。例如1954年大兴安岭森林资源调查中,选用的标准木(计算木)、落叶松为7008株;白桦为797株。这些标准木(计算木),全都以二公尺为一个区分段,测定出其带皮和去皮材积;
In the production work, especially in the measurement tree tabulation work, often to determine the thickness of the bark and its volume. For this work, the method used now is to measure the thickness of the bark after measuring the thickness of the bark on one or both sides of the trunk at a certain distance. In mass production and research work, this work requires an extremely large amount of labor. For example, in 1954 Daxinganling Forest Resources Survey, the selection of standard wood (calculated wood), larch 7008; white birch 797. The standard wood (calculation of wood), all with two meters as a section of the determination of its skinned and peeled volume;
