摘  要：
为确定不同造林密度形成的人工华山松林的合理抚育间伐强度和具体间伐措施,对不同间伐强度下2种不同密度人工华山松林的林木平均胸径、树高和单位面积蓄积变化进行研究。结果表明,一般密度华山松人工林间伐强度效果为:30%>35%>25%>45%>50%>20%>60%>10%>0%,保留株数以1 830株/hm2左右最好,在抚育间伐实施中采取3株中选伐1株与4株中选伐1株交替使用措施效果最好;密植华山松人工林间伐强度效果为40%>45%>35%>50%>30%>60%>25%>20%>10%>0%,保留株数以2 985株/hm2左右最好,在森林抚育实施中采取2株中选伐1株与3株中选伐1株交替使用效果最好。

摘  要：
In order to determine a rational intensity of tending and intermediate cutting and some concrete measures for pine forests under different planting densities,we have done some research on the average breast high diameter,tree height,and the changes of forest area and forest volume of varying-density pine forest under different intermediate cutting intensities.The results showed that intermediate cutting intensity effect of general density pinus armandi plantation was followed as: 30% > 35% > 25% > 45% > 50% > 20% > 60% > 10% > 0%,It’s better to keep about 1830 trees per hectare,and it works the best when intermediate cutting 1 in 3 trees and 1 in 4 trees are used in alternation;For the high-density plantation,intermediate cutting intensity effect was followed as 40% > 45% > 35% > 50% > 30% > 60% > 25% > 20% > 10% > 0%,it’s better to keep about 2985 trees per hectare,and it works the best when intermediate cutting 1 in 3 trees and 1 in 4 trees are used in alternation.
