长白山红松阔叶林鸟类群落多样性与稳定性研究

Study on species diversity and stability of the bird community in korean pine-broadleaf forest of Changbai Mt.

根据连续3 a的样地统计资料,采用物种数、群落密度、Shannon-Wiener多样性指数、Pielou均匀度指数和Simpson优势度指数,分析了长白山红松阔叶林鸟类群落的多样性与稳定性状况。结果表明,在该类型稳定的森林群落中,鸟类群落指数年度周期变化的季节性明显,年间变化较小,均匀度维持较高;物种组成年度间相似性较大,优势种类组成完全相同,群落具有极高的稳定性特点。

The species diversity and stability of the bird community in korean pine - broadleaf forest of Changbai Mt. was analyzed using the number of species, community densities, Shannon - Wiener index of species diversity, Pielou index of evenness and Simpson index of dominance based on the continuous statistic data collected on the sample plots in 3 years. The results showed that in this type of the stable forest community, the seasonal periodicity is obviously, the change between years is small, and the evenness maintains a higher level for the bird community index. The species composition is similar and the dominant species are all the same between years. Thus it showed that there is a special feature in the bird community.
