| 摘 要： | 在云南省石屏牛达林场小白得林区,对造林密度为4 464株/hm2的14年生云南松人工林,设置了伐除林分中林木株数15%、25%、35%、50%的4个间伐强度试验,以研究不同间伐强度对云南松人工林生长的影响。通过对不同间伐强度间伐3年后林木的胸径、树高生长量和林分单株材积以及单位面积活立木蓄积生长量的测试分析,提出该云南松人工林幼林期最佳的间伐强度为35%。

| Abstract: | Choosing the 14 years old Pinus yunnanensis plantation with the density of 4464 trees/hm2 in Niuda forest farm of Shiping County as study target,the effect of intermediate cutting intensity on stand growth was studied using four kinds of treatments,namely cutting 15 %,25 %,35 % and 45 % of the whole tree number.Based on the investigation results of increment of DBH,height and individual tree volume on the treated stand three years after intermediate cutting,it was proposed that the optimum intermediate cutt... |
