| 摘 要： | 林分生长阶段划分是定向经营不可缺少的基础之一。为此采用Ｆｉｓｈｅｒ最优分割法对黑河地区天然落叶松林的１２２块样地进行了林分生长阶段划分。以研究生长阶段和定向经营的关系。结果表明：黑河地区天然落叶松林分胸径成熟至少需３３￣３４ａ。材积成熟至少需４５ａ以上；阴坡生长期比阳坡长３￣７ａ，生长速率比阳坡慢；阳坡宜于发展短周期商品林；阴坡可用作发展中长周期商品林。

| Abstract: | The growth period of nature larch stand in Heihe district was diveded in to 5 stages with Fisher method based on 122 sample plots. The relation between the growth stages and aim-classification management was explored. In Heihe District, the sub-mature stage for the stand is 33-34 years and the age for volume mature is obove 45. The sub-mature age of the larch stand on shady slope is 3-7 years longer than that on sunny slope, and the growth speed is much slower. For the difference in growth between shady slope and sunny slope, the author suggest that the sunny slope is suitable to develop the commercial forests with a short rotation and the shady slope is suitable to develop the long-rotation commercial forests. |
