摘要
通过对杉木人工林进行强度、中度、弱度及不间伐4种不同强度的间伐处理后,观察对比其平均胸径、平均树高、单株材积计单位面积蓄积量的增长变化,结果表明:间伐强度对平均胸径及单株材积的生长影响显著,其随间伐强度的增加而增大;而间伐强度对平均树高及单位面积蓄积量的生长影响则不明显。
Through strong, medium, weak and no thinning 4 kinds of different thinning treatments on the Chinese fir plantation, the average DBH and average tree height, individual volume meter volume per unit area of growth chang- es were studied. It has been found thinning intensity had significant effect on the mean DBH and individual volume growth with the increasing thinning intensity, and the effects of thinning intensity on the average tree height and unit area accumulation were not obvious.
