| 摘 要： | 通过对同一造林地3种不同坡位的大青杨(Populus ussuriensis)人工林生长情况进行的调查与分析,结果表明:3处位置即坡下位、中位、上位(海拔分别为700m、750m、800m)的大青杨树高和胸径生长量均有显著性差异;中位(海拔750m)处树高和胸径生长量最高,极大值均出现在此区域。因此,建议营造大青杨人工林应尽量选择坡中位。

| Abstract: | Analysis of growth of Populus ussuriensis plantation on three kinds of slope positions in the same afforestation was conducted.Result shows that: growth of tree height & DBH of Populus ussuriensis on three positions,that is,lower,middle & upper slope(elevation respectively being 700 m,750 m,800 m) show significant differences;tree height & DBH on middle slope(elevation 750 m) are high;the great value appear in this area.Therefore,it is proposed that constructing Populus ussuriensis plantation should choose the middle slope. |
