轮伐期是表示林业生产周期的一种方式。具体地说就是用材林中采取皆伐或伐区式渐伐的经营单位进行永续利用的生产周期。所以,凡是采用皆伐或伐区式渐伐的经营类型,都要确定轮伐期。对于理想的法正林(即各龄级的森林面积相等)来说,轮伐期就是森林成熟龄,或叫森林主伐年令。 Rotation is a means of expressing forestry production cycles. Specifically, it is the production cycle of sustainable use of timber plantations that adopt clear cutting or cutting-down style of cutting units. Therefore, all types of operations that use either clearcutting or cutting-edge cutting should be determined by the rotation period. For the ideal Fazhenglin (ie, the forest area is the same for all age groups), the rotation period is the forest mature age, or the annual forest harvesting order.
