摘要
通过对中亚热带常绿阔叶林64个林隙的559株边缘木的调查,研究其径级和高度级的结构特征,用韦布尔分布(Weibull)模型和正态分布分别拟合径级和高度级分布.结果表明:中亚热带常绿阔叶林林隙边缘木径级分布符合Weibull分布,不符合正态分布;而高度的分布既符合Weibull又符合正态分布.
Through field investigation of 64 gaps in midsubtropical evergreen broadleaved forest in Wanmulin Natural Reserve of Fujian Province,there were 559 edgetrees.This paper dealt with the characteristic of structure of DBH classes and tree height classes,and simulated the DBH classes and tree height classes distribution with Weibull model and Normal distribution model.The results showed that the distribution of DBH classes of gap edgetree followed Weibull,but didn't follow Normal distribution,the distribution of tree height classes followed both Weibull and Normal distribution.
