在森林三类调查(即作业设计调查)中,常常需要测定林分平均高,而林分平均高通常采用依径阶分布,实测15～25株样树,绘制树高～胸径曲线法测得。既浪费人力,又浪费物力(必要时需伐木),由于样树的代表性问题而影响调查设计精度。而林分优势木平均高是林分中最稳定的调查因子之一,受生产作业及林分密度影响较小。事实上,优势木 In the three types of forest surveys (ie, job design surveys), it is often necessary to determine the average height of the stands, while the average height of the stands is usually based on the radial order distribution. Measured from 15 to 25 sample trees, the height- . It not only waste manpower but also waste material resources (need to cut wood if necessary), which affects survey design accuracy due to the representativeness of the sample trees. However, the average high stands of dominant wood is one of the most stable investigation factors in the stand, which is less affected by production operations and stand density. In fact, the dominant wood
