摘　　要：全文对杨桦次生林下红松幼树的最佳生长条件进行了研究。结果表明,林下无灌木或少灌木、距离立木1.5m以外、林冠郁闭度0.5-0.6为红松幼树更新的最佳条件。同时,提出了通过胸径与林分密度的关系对林分郁闭度进行控制的直接方法。In this article,the optimal growth condition for young tree of Pinus koraiensis in secondary forest was studied. The results were showed that the optimal regeneration condition for young tree of Pinus koraiensis is no shrub or fewer shrub understory,more than 1.5m from stocking and canopy density is 0.5-0.6. At the same time,the direct method to regulate canopy density by use of the relationship between diameter breast-height and stand density was put forward.
