贵州河流冬季水鸟组成、分布及多样性初步分析

Preliminary Research on Composition,Distribution and Diversity of Water Birds in Rivers of Guizhou Province in Winter

2010年11-12月采用样线调查法对贵州山区11条主要河流分布的水鸟进行了生态学研究,内容包括水鸟种类组成、分布、多样性、密度以及种间关联分析。结果表明：贵州山区河流分布的常见水鸟共有17种,隶属7目8科。水鸟多样性明显低于湿地等典型生境,多样性分布不均匀,物种关联不显著。开展河流鸟类生态学研究,不仅是对当前鸟类生态学研究内容的重要补充,更具有突出应用意义。

An ecological investigation was made on the water birds of 11 main rivers in mountainous area of Guizhou by line transects method from November to December in 2010.The content included composition,distribution,diversity,density and analysis of interspecies associations.The results showed that there were 17 common water bird species in total belonging to 7 orders,8 families in rivers of Guizhou mountainous area.The diversity of water birds in this area was uneven distributed and significantly lower than in typical habitat like wetland.No significant difference was observed in the interspecies associations.Therefore,study on river bird ecology was not only an important supplement to current bird ecology research,but also had significant application value.
