| 为探究森林抚育对森林资源变化和生态状况的影响,对黄柏山林场杉木中龄林2010—2016
年间监测样地与对照样地森林抚育成效的监测数据进行分析。结果表明,在一定密度范围内,不同抚育强度均能促进杉木中龄林胸径、单株材积和单位面积蓄积量的增长,抚育间伐强度越大,林分
平均胸径增长越大,增长率提高了10.64%~34.04%,单株材积较对照提高了1.46%~25.13%。在短期内蓄积量增长不显著,但随着经营年限的增加,林木胸径逐渐增大,蓄积量会逐步增大。抚育间伐也能够促进杉木林分平均树高增长,但中幼龄阶段树高增长表现不显著。 |

| To explore the impact of forest tending on changes in forest resources and ecological conditions,
this study analyzed monitoring data from sample plots and control plots of middle-aged Cunninghamia lanceolata at Huangbaishan Forest Farm from 2010 to 2016. The results indicated that, within a
certain density range, different tending intensities could promote the growth of diameter at breast height
(DBH), individual tree volume, and stand volume per unit area in middle-aged Cunninghamia lanceolata
plantations. The greater the thinning intensity, the larger the increase in average DBH, with growth
rates improving by 10.64% to 34.04%. Individual tree volume increased by 1.46% to 25.13% compared
to the control. In the short term, the increase in stand volume was not significant. However, as the
management period extended, the DBH gradually increased, leading to a progressive rise in stand volume.
Thinning also promoted the growth of average tree height in Cunninghamia lanceolata stands,
though the increase in height was not significant during the young to middle-aged stages. |
