摘要
本文应用 Weibull分布研究了毛竹林分直径结构规律 ,从拟合结构以及卡平方 (χ2 )检验结果得出毛竹林分直径分布密度函数曲线呈山形曲线 ,且为正偏。
This paper aims to study diameter structure regularity of Phyllostachys pubescens stand by way of WeiBull distribution. From analysed result and χ 2 tested result we draw a conclusion that the diameter distribution density function of Phyllostachys pubescens stand take on Mountain shape curve positive direction deflection. This will bring us certain theoretical?practical signficance which study structure regularity of Phyllostachys pubescens stand and conduct scientific operation for Phyllostachys pubescens stand.
