摘　　要：通过对现行的黑龙江省森工林区一元立木材积表、黑龙江省国有林区根径立木材积手册验证发现,立木材积表为围尺胸径材积表,如果使用的是轮尺,则需要先换算成对应的围尺胸径值,再使用该表;根径材积表中的根径对应的胸径是轮尺胸径,但根径是轮尺根径还是围尺根径已无法确认,想要查表得到立木材积,尚需再导算出对应的围尺胸径值。建议由上级主管部门组织技术力量对全省森工国有林区进行补充调查修定不同测量场景下的对应材积表,方便用户使用。Through the verification of the current one-dimensional timber volume table in Heilongjiang forest industry area and the manual of the root diameter standing volume of the state-owned forest areas in Heilongjiang Province,it is found that the volume table of the standing wood is the volume table of the diameter of the round chest.If the scale is used,it is necessary to convert it into the corresponding diameter of the circumference chest before using the table;the diameter of the root diameter in the root volume table is the diameter of the round rule,but the root diameter is the root diameter of the wheel scale or the diameter of the root of the circumference ruler cannot be confirmed.If you want to find the volume of the standing wood by looking up the table,you need to guide and calculate the corresponding diameter of the circumference.It is suggested that the superior competent department organize technical forces to make supplementary investigation and fix the corresponding volume table under different measurement scenarios for the convenience of users.
