摘要
根据杉木林胸径和树冠幅相关规律,建立了杉木密度控制数学模型,可推算间伐后立木胸径增值指标并确定间伐强度和间隔期。
Based on the relation between DBH and crown of C. lanceolata, the mathematical model for controlling the density of C. lanceolata was made. It can be used to calculate the increasing values of DBH for stands and determine the intensity of intermediate cutting and aitting interval.
