| 摘 要： | 在黑龙江省带岭林业实验局和铁力林业局落叶松人工林采伐迹地上,采用现场调查和数据分析的方法,对不同采伐强度、不同林分密度与保留木损伤率之间的关系进行了研究,结果表明:落叶松人工林在作业后,保留木损伤率不随采伐强度、林分密度的增加而增加,且伐木损伤率、集材损伤率呈现先增加后降低的相似态势。 |
| 关 键 词： | 采伐 落叶松人工林 保留木 损伤 |

| Abstract: | The relationships between cutting intensity,stand density and damage rate of residual trees on the logged sites of larch plantations in Dailing Forestry Bureau and Tieli Forestry Bureau of Heilongjiang Province were studied by means of site measuring and data analysis.Results indicate that the damage rate does not increase with increasing cutting intensity and stand density.The damage ratio and the skidding damage ratio of felled trees exhibit the same changing tendency,that is,both increase first and then decrease. |
