摘要
虽然用材林轮伐期研究长期受到国内外众多学者的关注,但有关轮伐期的内涵、轮伐期确定的标准、轮伐期模型选择以及相关变量对轮伐期的影响等方面,依然是众说纷纭,无法为构建用材林提质增效培育模式提供坚实的理论基础.本文通过梳理国内外有关轮伐期确定方面的研究成果,并以我国杉木用材林试验数据作为支撑,意在展示不同轮伐期确定准则、方法和相关影响因素对轮伐期确定的作用机理和过程,并对未来轮伐期的研究方向进行了展望.
Abstract
Although the study of forest rotation has attracted the attention of many scholars both domestic-ally and internationally,there are still divergent opinions on the connotation of optimal forest rotation,the criteria for determining the optimal forest rotation,the criteria for determining the rotation,and the impact of related variables on the optimal forest rotation,which cannot provide a solid theoretical basis for develop-ing a cultivation model for improving forest plantations.This paper summarized the research results on de-termining the optimal forest rotation,and used experimental data of Chinese fir plantations to demonstrate the different criteria,methods,and influencing factors in determining the optimal forest rotation.It also provides prospects for future research directions.
