摘　　要：在云南省富源县西北部国有三道箐林场的林地中设置计75株华山松的试验地,通过调查获得立木材积,将其作为四种测定方法对比的基准值。然后分别采用四种测定方法得到涉案林木材积,通过对比四种方法测定的林木材积与基准值的误差,得出采用平均实验形数法计算涉案林木材积的精度最高。因精度较高,计算结果接近于采用平均实验形数法计算的涉案林木材积,在编制根径材积表时,也可用当地编制的根径材积表直接求算蓄积量。Seventy-five Pinus armandi trees in the forest land of the state-owned Sandaoqing Forest Farm in the northwest of Fuyuan County,Yunnan Province were selected as the experimental site.The volume of standing timber was obtained from the survey and used as a reference value for the comparison of the four measurement methods.Then,four measurement methods were used to obtain the volume of the wood involved in the case.By comparing the errors between the wood volume measured by the four methods and the reference value,it was concluded that the average experimental shape number method had the highest accuracy in calculating the volume of the wood involved in the case.Because of the high precision,the calculation result was close to that of the wood volume calculated by the average experimental shape number method,When the root diameter volume table was available,the volume can also be calculated directly from the local root diameter volume table.
