| 摘 要： | 为提高伐区采伐量测算的准确性,避免根径材积表引起的偏差,提出了通过建立根径与胸径的线性回归方程,把根径换算成胸径,直接查胸径材积表得出伐区实际采伐量的方法。对该方法进行详细说明,并举例。论述了该方法的适用范围及要点。

| Abstract: | In order to improve the precision of cutting volume assessment at logging sites and to avoid the deviation from the table of basal diameter volume,the paper proposes the method for actual cutting volume at logging sites by transforming basal diameter to breast diameter to direct consult the table of breast diameter volume,with the help of establishing linear regressive equation of combining basal diameter with breast diameter.The method in the paper is elaborated in detail and set some examples to further explain.Finally,the suitable range and key points of the method are also stated. |
