摘要
文章利用在赤峰市收集的419株低平地小冠型人工杨树样木资料,通过模型拟合初步确定胸径——材积数学模型,并对其进行线性化,确定最优数学模型,编制人工杨树一元立木材积表,以供参考。
In this paper, using the data of 419 sample trees of the flat small crown artitieial poplar collected in Chifeng; through the model fitting establish DBH --volume mathematical model, and the linear To determine the optimal mathematical model ,finally construct One-way Volume Table , for reference.
