北京西山静福寺地区鸟类多度分布格局

物种多度格局分析对理解群落结构具有重要意义。采用分割线段模型对北京西山静福寺地区鸟类群落物种数量关系进行拟合研究,并运用秩相关性分析对模型进行相关系数检验,结果表明:(1)该地区鸟类群落多度格局模型与分割线段模型显著相关,利用分割线段模型可以良好的拟合该地区鸟类群落多度格局;(2)鸟类多度分布格局具有时间和空间的双重属性;(3)月尺度上,1月与其他月份差异显著,森林群落间差异不显著;(4)季尺度上,冬季与春、秋两季差异显著,落叶阔叶林与针阔混交林差异显著,针叶林与落叶阔叶林、针阔混交林差异都不显著;(5)年尺度上,年变化差异不显著。

Bird abundance distribution patterns of Jing Fu Temple in Beijing Xishan

The analysis of species abundance patterns is fundamental to understand community structure. In the present paper, the broken stick model, used to describe the relationship between species and abundance, was used to study the quantitative relationships of the bird community of the JingFu temple in Beijing Xishan. The model was tested using a correlation coefficient with a rank correlation analysis. The results showed that: (1) The bird community structure in this area was significantly correlated with the broken stick model. The model could be used to fit the pattern of bird community structure well in the region. (2) The pattern of bird abundance varied temporally and spatially. (3) The results showed that the abundance pattern in January was significantly different to the other months, and there were no significant differences in forest communities monthly. (4) The abundance pattern in winter was significantly different from those in spring and autumn, and between between deciduous broad-leaved and coniferous-broadleaved forest, and neither deciduous broad-leaved nor coniferous-broadleaved forest were significantly different from the coniferous forest seasonally. (5) There was no annual significant difference.
