摘要:
 为研究珍贵用材树种观光木胸径与树高的关系,采用6种生长方程分别拟合观光木树高生长模型,并确定最优的树高生长方程。结果表明,观光木的最优生长模型为二次方程,其最优曲线方程为H=0.059 3D2-0.330 3D+7.1141,拟合精度较高,该模型可实现观光木人工林林分树高的有效估测。8年生观光木人工林已出现林木分化,可实施间伐,改善林内光环境,促进林木的生长和材积的积累。
Abstract:
 Six height growth equations were used to fit the growth of Tsoongiodendron odorum to study the relationship between DBH and tree height in different ages and to determine the optimal growth equation.The results showed that the optimal growth model was the quadratic equation,H=0.059 3D2-0.330 3D+7.114 1,its fit accuracy was extremely high and indicated that the model could be used to achieve the effective prediction of the height of T.odorum.Tree differentiation occurred in the 8-year-old forest strands,indicating that thinning management could be implemented to improve the forest light environment,promote the growth of trees and the volume accumulation.
