落叶松人工林皆伐后是否可继续再造落叶松，地力是否下降和重茬林如何经营是林业生产上亟待解决的问题。本文对暗棕壤上生长的落叶松一代、二代人工林和针阔混交林进行研究对比后，认为肥沃和较肥沃土壤营造二代林是可行的。且无酸化现象。二代林初期生长较缓慢，其原因是皆伐时人为因素所致，与二代更新无关。
Larix gmelinii plantation whether clear after cutting can continue to re-create larch, whether the decline in soil fertility and continuous cropping forest management is the issue of urgent need to be resolved. After comparing and contrasting the larch generation, the second generation plantation and the coniferous and broadleaved mixed forest grown on the dark brown soil, this paper suggests that it is feasible to create the second generation forest in the fertile and the more fertile soil. And no acidification. The early growth of the second generation forest is relatively slow, the reason is clear due to human factors, has nothing to do with the second generation update.
