摘　　要：根据实测的254株落叶松样木,以根径为横坐标,胸径为纵坐标,绘制散点图。依点的分布趋势表明,根径和胸径呈直线关系。所以适用直线方程Y=a+bx作为两者间相关关系的数学模型。再根据现行一元立木材积表,进而编制根茎材积表。此表将为审核采伐林木蓄积提供科学依据。Based on the measured 254 larch wood samples ,a scatter diagram is made with diameter ground for abscissa, and diameter breast height for ordinate. According to the distribution of points, the relationship between diameter ground and diameter breast height is linear. Therefore, linear equation（ Y = a ＋ bx）was used as the both relationship mathematical model. Furthermore, according to the existing one-dimensional tree volume table, the preparation of rhizome volume table is available. This table will provide a scientific basis for the examine and verify of harvesting.
