| 摘 要： | 天保工程实施以来,工程区停止一切商品性采伐,2004年随着抚育间伐的启动,总结抚育间伐试验,进行人工商品林抚育间伐以Pn=33%的机械间伐强度为最好,不仅能提高林分平均直径生长量、林分的生长率、单位面积的蓄积量,还能提高生态防护效能。是1种较好的间伐方法。

| Abstract: | All commercial harvests have been stopped in the natural forest protection program area since implementing the project. With start-up period of tending and thinning in 2004, sum up experiences, carry out the tending and thinning of the man-made plantation that performs the best with mechanical thinning intensity by Pn = 33%. It can not only enhance average diameter increment of the stand, the growth rate, volume of unit area, but also can enhance the effect for the ecological protection which is a soundly thinning method. |
