【摘要】 2013—2015年,在北京动物园的自然生境中通过悬挂人工巢箱招引鸳鸯,基于巢址因子分析开展了鸳鸯巢址选择的研究.结果表明:两类主效因子对鸳鸯的巢址选择具有重要的影响,第一大类是植被盖度、高度及多样性,这是影响鸳鸯巢址选择的最重要的影响因子,其中,乔、灌、草三个空间层次的植被特点可代表鸳鸯活动范围的生境特点;第二大类是干扰的影响,包含距道路和水源的距离,以及瞬时人流等因素.更多还原

【Abstract】 From 2013 to 2015,attracted Aix galericulata using the artificial nest boxes in natural habitats of Beijing Zoo,and research its nest site selection.The results of factor analysis show that there are three types of main factors effect on duck nest site selection.The first category is the coverage,height and diversity of the vegetation,which is the most important impact factor in the A.galericulata nest site selection.The three levels of spatial vegetation characteristics,such as tree,shrub and grass characteristics may represent the habitat characteristics where ducks live in it.The second category is the impact of interference from the distance to the road and river,and the instantaneous flow of people,which also influence the duck nest site selection.更多还原
