摘要
为探索微地域对幼林生长的影响 ,采用定位测树和方差分析方法分析了长白落叶松幼林期间的地径、树高和树冠的生长量。结果表明 :微地域的地形因子对幼林地径和树冠的影响最明显 ,对树高的影响较明显 ,这种影响突出表现在阳坡上部和下部之间 ;不利于幼林生长的微地域部位有阴坡汇水区、阳坡下部汇水区。
In the paper, by measuring height, diameter, crown of trees and analysis of variances of young larch stands on different ravines, the authors studied the effects of ravince factors on young Larix olgensis growth. The results indicate that ravines obviously affect the collar diameter and crown growth, but affect lightly the height growth of the tree; the differences obviously take place between upper and lower parts of sunny slope; the sites that comparably unsuitable for young Larix olgensis growth are the lower catch part of the sunny slope, shady slope and lower sunny slope on the middle ravine.
