摘　　要：利用二类调查布设的固定样地,收集207株样木调查资料,分别采用5个方程进行回归拟合,选出杉木人工林地径材积表的方程模型,利用一元材积表和二元材积表导算编制一元地径材积表,并进行比较,结果表明二元材积表导算地径材积表的方法精度较高,基本满足林业生产所需精度要求,可以提供林业生产服务。This article uses fixation swatch founding for second-class investigation to obtain character of 207 sample trees, by which mathematics model of ground diameter volume table of Chinese Fir were deduced by regressing and imitating with five of equations respectively, and used unitary and binary volume tables of timber respectively to reckon an unitary ground diameter volume table, then compared the two ground diameter volume tables, so that a ground diameter volume table of Chinese Fir in Yanping District was compilated to satisfy essentially the precision demand of forestry production, and to serve forestry production.
