摘要
依据75株标准木资料建立了华北落叶松单木管道模型。提出了与分层厚度无关的比管道长的计算方法。
Based on data of 75 sample trees, the pipe model for individual trees of Larix principis-rupprechtii Mayr. was made. This model can correctly reflect the close relationship between the quantity of assimilating tissue and that of non-assimilating tissue. The authors suggest a method for calculating specific pipe length, which is independent of the dividing thickness
