摘要 2008年5-7月和2009年5-7月对黑龙江省安邦河湿地和大庆龙凤湿地骨顶鸡种群的巢址进行了调查,共获得136个巢样方和139个对照样方数据,并对巢样方以及对照样方的12种生态因子进行了测量.巢样方与对照样方在植被高度、植被盖度、距干扰源距离、距明水面距离等几方面差异显著.逐步判别分析结果表明:隐蔽条件是骨顶鸡巢址选择的主要因子,而水因子、种内竞争及种间竞争等为次要因素.巢频次分析结果表明骨顶鸡偏好植被高度、盖度、水位适中,距明水面较近、植被较稀疏的区域进行筑巢.此外,人为干扰对骨顶鸡的巢址选择影响不显著,但骨顶鸡的巢址选择受其领域性的强烈影响. Research on nest-site selection of the Common Coot(Fulica atra)was carried out in Anbanghe Nature Reserve and Daqing Longfeng Nature Reserve in Heilongjiang province since May to July of 2008 and 2009.12 ecological factors were chosen to compare 136 nests plots with 139 comparison plots.There were significant differences between nest plots and comparison plots on vegetation height,coverage,vegetation density,distance to disturbance,as well as distance to open water.Stepwise discriminate analysis and was used combined with observation to investigate the nest-site selection of coots in breeding season.Results showed that:coverage of nest was the main factor for coot's nest-site selection,compared with water,inter-specific and conspecific competition which were the secondary factors.The coots favored to nest in area with middle vegetation coverage and height,moderate water level,near to open water and thin reeds and cattails;impact of human disturbance on nest site selection was weaker.Territoriality played important role in habitat selection of the coots.
