摘要
Abstract
This study focused on a 36-year-old Fokienia hodginsii plantation in Shanghang County,Fujian Province.Annual growth data for diameter at breast height(DBH),tree height and stem volume were obtained from sample trees using the stem analysis meth-od.Five classic theoretical growth equations,including Richards and Korf,were fitted through non-linear regression to select the opti-mal growth models.The results indicated that:①the single-tree growth of F.hodginsii followed a typical'S'-shaped curve,but sig-nificant allometry existed in the growth rhythms among different mensuration factors.②The Richards equation was the optimal model for DBH and stem volume growth,while the Korf equation was optimal for tree height growth.③Validated both internally with stem a-nalysis data and externally with plot-measured data,the optimal models showed high agreement between predicted and measured val-ues,with all relative errors below 5%and no significant differences between them(P>0.05);the selected Richards and Korf equa-tions can accurately simulate and predict the single-tree growth dynamics of F.hodginsii,providing a scientific reference for the pre-cision forestry and sustainable management of its plantations.关键词
