摘　　要：2006年3～6月,在上海野生动物园百鸟园内对白鹇的巢址选择进行了初步研究,分析和讨论了营巢小生境、营巢背景植物高度、郁闭度、人为干扰、水源、投料点、坡度、巢间距这8类生态因子对白鹇巢址选择的作用,发现在食物充足、繁殖空间环境有限的情况下,隐蔽条件、营巢背景植物高度、坡度依然是影响白鹇巢址选择的主要因素之一,白鹇会通过调节水源和投料点的距离、改变巢的位置、增加巢的密度、选择较高郁蔽度的营巢地来弥补空间环境的不足。Nest site selection of silver pheasants in a semi-natural environment in captivity was analyzed with 8 ecological factors,from March to June,2006.Results showed that,in the environment of Shanghai Wild Animal Park with plenty of food,yet space limited,concealed conditions,heights of trees in the back ground of nests and slopes were still main factors of nest sites selection and nesting sites were regulated by distances from water sources and feeding spots and,in limited spaces, by increasing the nest density and more close canopy.
