采伐强度对林分蓄积生长量的影响

The Impacts of Cutting Intensity on Stand Volume Growth

以云冷杉林、阔叶红松混交林、针阔混交林、落叶松林４种林分分类型为例、分析和讨论了采伐强度对不同林分蓄积生长量的影响。结果表明：采伐强度因林分类型不同。伐后林分蓄积生长量也不相同、云冷杉林、阔叶红松混交林、针阀混交林、落叶松林，采伐强度分别在６０％、３０％～５０％、２０％、４０％时林分蓄积生 长量较大。

Taking spruce and fir forest stands, broad-leaved Korean pine stands, mixed forest stands of conifer and broad-leaved and larch forest stands for example. the author analyzes the impacts of cutting intensity on volume growth. Results show that the volume growth after cutting are different in different kinds of stand types. The stand volume growth of spruce and fir forest. broad-leaved Korean pine forest. mixed forest of conifer and broad-leaved and larch forest are preferable as the cutting intensity is 60%, 30%-50%. 20% and 40% respectively.
