摘要
运用5种概率分布律对南平市延平区77块天然阔叶林样地的直径分布进行拟合。结果表明,南平市延平区天然阔叶林的直径分布用伽玛分布(gammadistribution)表示较好。探讨这些规律对于天然阔叶林的合理经营以及进行森林调查均具有重要意义。
Five probability distribution laws were applied to analyse diameter-distribution of natural broad-leaved forests of 77 plots in Yanping District of Nanping City.Compared with the results of the five probability distribution laws,the diameter-distributions of the natural broad-leaved forests obey mainly gamma distribution.The resulting principle will provide an important guide for rational management and survey of natural broad-leaved forests.
