摘  要:
以小兴安岭水胡黄硬阔叶混交林为研究对象,对林分进行不同强度的抚育采伐并更新,调查林分主要树种及林下更新苗木的生长情况并分析,结果表明:中度采伐更有利于水曲柳、胡桃楸、黄菠罗胸径和单株材积的生长,较未采伐的林分高出40.87%、87.11%、25.26%和72.94%、20.68%、28.47%;强度采伐能够很好的促进林下更新苗木地径和苗高的生长,较其他2种采伐强度高出10%以上。

摘  要:
The growth of dominant tree and regeneration of Fraxinus mandshurica、 Juglandis Mandshuricae and Phyllostachys sulphurea hardwood broad- leaved mixed forests were investigated after the stand were changed by different cutting intensities and regenerating. The results showed that the growth of DBH and individual volume of Fraxinus mandshurica、Juglandis Mandshuricae and Phyllostachys sulphurea were 40. 87% 、87. 11% 、25. 26% and 72. 94% 、20. 68% 、28. 47% better than the contrast in the stand under moderate cutting intensity. Hard cutting intensity could promote the growth of ground diameter and seeding height,and more than 10% better than the other cutting intensities.
