摘　　要：提出了林分平均胸径100倍圆法的测树方法、一般操作步骤与技术要求。通过100Dg圆公式含义设计了100倍圆法在生产上可实行的林分平均胸径实测方法,即100Dg圆圆内控制检尺法、100Dg圆随机检尺法、100Dg圆快速估测法、100Dg圆快速估测修正等4种方法,并进行了讨论。The paper proposes the dendrologic method, general operational procedures and technique requirements of the method of 100 times of circles of forest stand average breast diameter. The four applicable methods are designed with the formula of 100 Dg, namely method of control scaling inside 100Dg, method of random sample scaling of 100Dg, method of fast estimate of 100Dg, method of fast estimate and correction of 100Dg, all of which have been discussed.
