摘要
本文在对6年生杉木和马尾松标准木调查的基础上,应用相关分析方法,找出杉木和马尾松幼林各器官生物量与树高、胸径之间的相关关系。应用Y=aD^b和Y=aD^bH^c数学模型建立了杉木和马尾松各器官生物量的估测数学模型。其中以Y=aD^bH^c的数学模型为最佳,可作为一定立地条件下的杉木和马尾松幼林的生物产量估测。
In this paper,based on the surveys of the mean Chinese fir and masson pine trees at the age of six, the relations between various organs of tree, tree height and diameter at breast are obtained by the method of correlation analysis. The mathematics models for every organ of tree have been established by applying the models of Y=aDb and Y=aDbHc, with the model of Y=aDbHc being the best, which could be used for forecasting biomass of young Chinese fir and masson pine plantation in certain site conditions.
