福建将石自然保护区鸟类物种相对多度模型的拟合研究

应用对数级数分布模型、对数正态分布模型、几何级数分布模型和分割线段模型对福建将石自然保护区鸟类物种相对多度分布格局对比研究结果表明 ,对数级数分布模型、对数正态分布模型能较好地描述将石自然保护区鸟类多样性 ,而几何级数分布模型和分割线段模型则不适于描述该自然保护区鸟类多样性 ;“多度 /频度”图解可较好地反映对数级数分布模型拟合效果 ,丘陵山地鸟类群落物种相对多度不遵从对数级数分布 ,各生境群落百分率相似性指数说明各生境群落百分率相似性较低。

Application of various patterns to the study on relative abundance of bird species in the Jiangshi Natural Reserve Zone of Fujian Province

In this paper, the relative abundance of bird species was studied by using the patterns of log series distribution, log normal distribution, geometric series distribution, and broken stick model in the Jiangshi Nature Reserve Zone of Fujian Province. The results show that the relative abundance of bird species obeys the logarithmic series distribution and the log normal distribution that can be used to describe the bird species diversity well, and the geometric series distribution and the broken stick model can not be used to describe it; and the diagrammatization of "abundance/frequency" reflects the effect of the logarithmic series distribution well, and the relative abundance of bird species does not obey the logarithmic series distribution in the hill and hilly county, and every community percent similarity (PS) is lower.
