摘　　要：用正形数、胸高形数和经验回归方程３种方法编制的樟子松人工林二元材积表，其精度比较的结果表明，正形数法最优，其次是胸高形数法。直接用经验回归方程编制的一元材积表和利用树高曲线把胸高形数二元材积表导算成一元材积表的精度比较结果表明，后者优于前者．因此，利用胸高形数是编制材积表的有效方法。This paper reports on the construction of the volume table for artificial pine (Pinus sylvestris var. mongolica) stands of Saihanba Forest Enterprise of Hebei Province. Three kinds of two - way volume table were construted by the normal form factor, the breast height form factor and the Yamamoto formula which shows best goodness of fit to the measured results from seven kinds of experimental regression formula. Though the comparison among the three kinds of volume table shows that the normal form method has highest degree of accuracy, the breast height method has a higher degree of accuracy, the breast height method is accepted because of its universal idea and precision.Next, two kinds of one - way volume table were constructed using the experimental regression formula and the breast height form factor with the heightdiameter curve the two-way volume table is transformed into the one-way volume table. Though the comparison between the two kinds of volume table shows that the breast height method has a higher degree of accuracy, the breast height method is accepted. The result showed that the breast height method is a more effective method.
