辽东山区抚育间伐对红松林分生长的影响
|
摘要
为探讨辽东山区抚育间伐对红松林分生长的影响,对红松林分实施不同强度的抚育间伐试验,并进行林分的平均高、胸径、材积等指标的测量与分析,结果表明:与对照区域相比,间伐区域红松直径生长量可提高6%～15%,生长量的增加幅度随间伐强度的增大而增大;抚育间伐对立木材积影响明显,通过间伐能生产出高规格、高质量的大径级材,大强度抚育间伐可使红松主伐时间提前20 a以上,但抚育间伐对树高的生长影响较小。
In order to explore the effects of tending and thinning on the growth of Pinus koraiensis forests in the mountainous areas of eastern Liaoning Province, the different intensity of thinning and thinning tests were conducted on Pinus koraiensis, and the average height, DBH and volume of the stands were measured. Result shows that: Compared with the area, the diameter growth of Pinus koraiensis in the thinning area can be increased by 6%-15%, and the increase of the growth amount increases with the increase of the thinning intensity;the thinning effect of the thinning is obvious, and the high yield can be produced by thinning. High-quality large-diameter grades, high-strength thinning can make the main cutting time of Pinus koraiensis more than 20 a, but tending thinning has little effect on the growth of tree height.
