摘　　要：以武夷山国家公园内毛竹纯林为例,利用均匀度、整齐度2个指标分析了10个标准地的胸径和树高分布规律,并利用正态分布(ND)、对数正态分布(LND)、贝塔分布(BD)、伽玛分布(GD)、韦布尔分布(WD)5个模型方法分析了胸径和树高结构规律。结果表明:毛竹林胸径和树高结构规律显韦布尔分布(WD),并拟合了胸径和树高结构规律模型;结合胸径树高关系模型,建立了基于关系模型的树高WD模型,并通过卡方检验。研究结果为毛竹纯林的人工抚育采伐及其他森林经营管理提供科学技术支持。Taking Phyllostachys edulis pure forests in Wuyishan National Forest Park as an example, two indexes, evenness and uniformity, were applied to analyse the distribution regularity of DBH and tree height of 10 sample plots. On this basis,five model methods, the normal distribution（ND）, lognormal distribution（LND）, beta distribution（BD）, gamma distribution（GD） and weibull distribution（WD）, were used to analyze the distribution regularity of DBH and tree height. According to chi-square test, the results showed that the regularity of DBH and tree height was WD, and the regularity model of DBH and tree height was created. On this basis, the WD model of tree height was established based on the DBH and tree height relational model, and it passed chi-square test. The results provide scientific and technical supports for the cultivation and felling of Phyllostachys edulis pure forest and other forest management.
