| 摘 要： | 通过对大兴安岭、小兴安岭和长白山部分林区不同林型的调查，分析了不同采伐强度对林分蓄积生长量和更新效果的影响，并应用统计学原理，对不同采伐强度与林分年平均蓄积生长量和年平均更新株数进行拟合分析，得出不同林型不同采伐强度与林分蓄积年平均生长量和年平均更新株数的相关关系。结果表明：采伐强度与林分年平均蓄积生长量和更新株数间呈抛物线关系。

| Abstract: | According to the investigation data in parts of Daxing'an Mountain, Xiaoxing'an Mountain and Changbaishan forest areas, the impacts of cutting intensity on volume increment and regeneration effects were analyzed. Meanwhile, the relations between different cutting intensities and annual mean increment of stand storage and the annual average number of regeneration individuals in different forests were presented by using statistic principles. Results showed that the relation equations was parabola equation between cutting intensities and annual average increment and annual average number of regeneration individuals of stands. |
