| 摘 要： | 确定杨树速生林适宜采伐期,与树种结构、林龄、林分密度和林木连年生长量有直接关系,当林分密度进入极限时,林木连年生长量开始从高峰下降,说明林分已进入适宜采伐期,实行适宜采伐期采伐作业,可获最佳经济效益。

| Abstract: | Felling period of fast-growing forest of poplar had direct relationship to tree species structure,stand age,stand density and current annual increment of forest.When stand density reached the limit,the current annual increment of forest began to decrease from the top.It showed that stand had already entered optimal felling period. |
