摘要：吉林延边地区目前所用一元立木材积表的误差，主要来源于估计各径阶高的误差。本文以双曲线为例，介绍三种多元树高曲线模型；称为自动调控树高曲线。在测定小班（或样地）直径分布时，同时测定小班（或样地）的断面积平均高，由此计算树高曲线，进而得到相应的一元立木材积表。其首选自动调控树高曲线式：Ｈ＝Ｈｍ·Ｄ／［Ｄ＋（Ｈｍ／Ｈｇ－１）Ｄｇ］。此式导出的一元材积表，经验证与实测材积的误差比原地区一元材积表减少约５０％。
It is proved that the error of one-entry volume tables presently used in Yan-bian District,Jilin Province mainly comes from the estimate error of the average heights indiameter classes. Three types of multi-entries height-diameter model,named self-adjustedheight-diameter curves,are introduced in this paper. The mean height of basal area are mea-sured while the diameter distribution is measured for one subcompartment(or plot). Height-diameter curve will be estimated from the mean height and diameter distribution,and then anone-entry volume model will be obtained. The results of the research show that the first choice of the type of height-diametercurves is the reduced hyperbolic type,H=Hm·D/[D+(Hm/Hg-1)·Dg](1) where D-diameter of a tree,H-its estimated height,Hg-mean height of basal area,Dg-basal area average diameter,Hm-height limitation(parameter).The self-adjusted one-entry volume models corresponding to equation(1)are developed. The results show that theerror of self-adjusted one-entry models is 50% less than that of the present one-entry volumetables used in Yanbian District.
