| 摘 要： | 对大兴安岭兴安落叶松用材林进行不同强度的采伐改造,采用集对分析法,对不同强度采伐后的土壤养分进行综合评价,对比采伐改造后土壤养分.结果表明：大兴安岭地区,兴安落叶松用材林中,采伐强度为19％时,土壤养分最优,低强度和高强度的采伐对土壤养分有负面影响,且采伐强度越高,土壤综合养分越差.

| Abstract: | The commercial Xing＇an larch low-quality forest in Great Xing＇an Mountains was tranformed by adopting different cut- ting intensities. The soil nutrients in the forest lands with different harvesting intensities were comprehensively evaluated by using the set pair analysis method and compared with those before the logging transformation. The results showed that the soil nutrient was opti- mal while the cutting intensity was 19% for the Xing＇an larch low-quality forest in Greal Xing＇an Mountains. Either lower cutting inten- sity or higher cutting intensity has a negative impact on soil nutrient, and the higher the cutting intensity, the worse the soil nutrient. |
