【摘要】 2011年10月至2012年9月,在浙江省宁波市天童国家森林公园对同域分布的白头鹎(Pycnonotus sinensis)、黑鹎(Hypsipetes leucocephalus)、领雀嘴鹎(Spizixos semitorques)三种常见鹎科鸟类的栖息地利用进行调查研究.采用生态因子对比分析和逐步判别分析法确定各季节三种鹎科鸟类的选择样方和对照样方在16个生态因子上的显著性差异,以及各季节影响栖息地利用的关键因子.结果表明:在不同季节三种鹎科鸟类的选择样方和对照样方在一系列生态因子上差异显著;影响三种鹎科鸟类栖息地利用的关键因子有明显季节变化;三种鹎科鸟类在不同生活史阶段的栖息地利用上存在一定程度的重叠和分离;在春夏繁殖期,三种鹎科鸟类倾向于利用乔木和灌木盖度较高并远离人为干扰的具有良好隐蔽性的阔叶林和灌丛;在非繁殖期,它们倾向于利用食物条件好的灌丛、农田等栖息地.更多还原

【Abstract】 Habitat use of three species of sympatric Pycnonotidae(Pycnonotus sinensi,Hypsipetes leucocephalus and Spizixos semitorques)were researched in Tiantong National Forest Park,Zhejiang Province,from October 2011 to September 2012.It was used to determine significant differences of sixteen ecological factors and the key ecological factors affecting three species of Pycnonotidae habitat use by comparison and stepwise discriminant analysis measured in selected samples and comparing samples in each of the respective seasons.The results showed that selected samples and control samples of three species of Pycnonotidae in the different seasons were significantly different on a series of ecological factors;The key factors affecting habitat use of three species of sympatric Pycnonotidae had obvious seasonal variation.The habitat use of three species of Pycnonotidae had a degree of overlap and separation in the different lifecycle stages.In the breeding season,three species of Pycnonotidae was apt to better sheltering broadleaved forests with higher arbor coverage and shrub with higher shrub coverage,avoiding human disturbance;In non-breeding period,they preferred to the shrub,farmland which had good food conditions.更多还原
