摘要
本文应用六种概率分布律拟合闽北天然次生林主要树种林木直径分布，并比较不同分布类型的拟合效果．结果表明，正态分布、威布尔分布的拟合效果较好．探讨这些规律对闽北天然次生林的合理经营及进行森林调查具有重要意义．
Six probability models were applied to analyse diameter distribution of main tree populations in natural secondary forests in north Fujian. Normal distribution and Weibull distribution models showed better fitness. The resulting principle will provide an important guide for forest management and survey.
