摘要
以汪清林业局 30a来实施择伐作业调查资料为依据 ,分析了森林择伐对林分的影响。结果表明 :择伐可以促进森林更新和生长 ,缩短择伐周期 ,调整了林分结构 ,改善林木组成 ;并且按照采伐量不大于生长量的原则确定择伐始伐立木直径。
According to the investigating data of selective cutting in Wangqing Forestry Bureau for 30 years, the impacts of selective cutting on forest stands are analyzed. The results show thet selective cutting can accelerate forest regeneration and growth, lessen the circle of selective cutting and improve the structure of forest stands. After this, according to the principle of cutting quantity less than growth, the diameter of starting to timber cutting is determined.
