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。
以小興安嶺水鬍黃硬闊葉混交林為研究對象，對林分進行不同彊度的撫育採伐併更新，調查林分主要樹種及林下更新苗木的生長情況併分析，結果錶明：中度採伐更有利于水麯柳、鬍桃楸、黃菠囉胸徑和單株材積的生長，較未採伐的林分高齣40．87％、87．11％、25．26％和72．94％、20．68％、28．47％；彊度採伐能夠很好的促進林下更新苗木地徑和苗高的生長，較其他2種採伐彊度高齣10％以上。

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 .
