利用角规调查蓄积量,具有操作简便、省工、速度快的优点,尤其在经营作业设计的现地复核工作中,利用此法能快速调查出蓄积量。一般调查方法是根据角规绕测的每公顷断面积和该林分的平均树高查表求得,这种方法的准确程度除了受断面积控制外,还要受到平均树高的制约。众所周知,准确 The use of angle gauge to investigate the volume, with the advantages of easy operation, labor-saving, fast, especially in the operation of the design of the local review of the work, the use of this method can quickly find out the volume. The general survey method is based on the cross-sectional area measured per hectare and the average tree height table of the stand, and the accuracy of this method is subject to the average tree height in addition to the area under control. Well known, accurate
