摘  要:
通过对叙永大安林场杉木林不同采伐强度的试验研究结果表明:不同的采伐强度对树高、胸径和林下植被种类、盖度的影响都较明显,并随着采伐强度的增大而增大,对林分蓄积量的影响是随着采伐强度的增大而增大。但采伐强度增加到一定数值后,单位面积保留株数减少,蓄积增长量反而呈下降趋势。因此研究区适宜的采伐强度为21%~30%。

摘  要:
Researches were conducted on impacts of different cutting strength on the Chinese fir plantation in Xuyong Daan Forest Farm.The results showed that the effects of different cutting intensity on tree height,diameter at breast height and understorey vegetation types,coverage were more obvious,and with the imcrease of cutting intensity the stand volume effect would increase.But when the cutting intensity increased to a certain value,the retained bamboo number in the unit area would reduce,and the volume growth amount would also decrease.Therefore the suitable harvesting intensity in the studied area should be 21%~30%.
