大兴安岭东南部兴安落叶松胸径生长率与材积生长率的关系研究

Growth Rate of Chest Diameter and the Growth Rate of Tinber Volume on Larix Gmelini in the East-S-outh of Daxinganling

兴安落叶松 ( L arix gmelini,以下简称落叶松 )是大兴安岭林区的主要树种 ,文章研究落叶松胸径生长率与材积生长率的关系 ,建立数学模型 ,使之通过测算胸径生长率来预测材积生长率 ,为简化材积生长量调查提供了理论依据。

Larix gmelini(The following is called larix)is a chief tree in the Daxinganling forest region.Study on the relation between the growth rate of chest diameter and the growth rate of timber volume,establish a mathematical model ,we can forecast the growth rate of timber volume by surveying and calculation the growth rate of chest diameter,provide the theoretical basis for simpllfying investigation on the growth volume.
