摘要
本文对大兴安岭西北坡林冠下兴安落叶松天然更新进行调查研究。结果表明:不同林型、郁闭度、坡度、坡向、采伐方式及采伐强度其更新效果明显不同。林分中的光照、温度、水分和土壤结构等是影响更新效果的主导因子。
This paper have investigated and researched natural regeneration of Dahurian Larch (Larix gmelinii) under the canopy of trees in the northwest slope of the greater Khlin-gan Mountains Inner Mongolia. It shows that there are very different results of regenerative effects with the condition of different forest type,gloomy degree,slope degree,slope direction, deforest methods and deforest degree.And it still shows,light,temperature,water and soil structure in the forest are main factors that influent the effects of regeneration.
