为提高常绿阔叶残次林的森林质量,提高常绿阔叶林的3大效益,应用“残次天然林改造及定向培育”技术,在样地里做了4种处理,对4种处理下的改造成效进行分析,结果显示在中度疏伐(84株/0.04hm2)时胸径生长和蓄积生长等各指标上都呈现明显优势;如果改造的目的是为了短期内得到大径材林分,则以强度疏伐(72株/0.04hm2)最为合适;如果要节省人力和财力,短期内获取较多的蓄积,则以对照(114株/hm2)较为合适。
In order to improve the forest quality of the evergreen broad-leaved secondary forest and improve the three major benefits of the evergreen broad-leaved forest, four treatments were made in the sample plots using the techniques of “secondary natural forest rebuilding and directional cultivation” The results showed that the DBH (84 / 0.04 hm 2) showed obvious advantages in DBH growth and accumulation growth. If the purpose of the transformation is to obtain large diameter in short term For the timber stands, it is most suitable for the intensity thinning (72 plants / 0.04 hm2). If it is to save manpower and financial resources and gain more accumulation in the short term, the control (114 plants / hm2) is more appropriate.
