林分改造是一种改善林分组成,降低立木中不适应生长环境条件那一部分的比例,改善低疏密度林分结构的有效方法,从而在整体上,提高了森林的生产力。也就是通过采用造林或抚育采伐的办法,以经济上有价值的林分代替低价值的林分。林分改造的概念仅适用于事先已把珍贵树种引入林分的那些抚育采伐类型。目前,尽管已经更多地采用了有助于保存幼树的主伐方式,然而由于强度采伐,在一系列多林地区,仍然可以看到树种更

The concept of reforestation applies only to those types of tending which have been introduced in advance into the stands. At present, despite the increased use of cutting practices that help conserve young saplings, species can still be seen in a range of multiple forest areas due to intensive logging
