白颈长尾雉(Syrmaticus ellioti Swinhoe)的生态研

本研究于1983年5月至1985年8月采用步行跟踪、典型样地调查等方法在浙江省内进行。 白颈长尾雉以常绿阔叶林和常绿针阔混交林为最适生境。乔木盖度低于50％时其活动强度明显下降,低于30％即绝迹。 白颈长尾雉春季存在两个日活动高峰。第一高峰在上午5∶00—7∶00出现;第二高峰在下午3∶00—7∶00之间。该雉白昼始止活动的时间和光照度有关,早晨,光照度达17—450lX开始活动;傍晚,在110—5lx光照度时停止活动。另外,活动还受天气的影响。 白颈长尾雉在浙江省分布于西部、南部和东部山区。但数量十分稀少,按C=10000N/WT计算,开化县夏、冬两季的相对密度为0.035只/公颐和0.069只/公顷。

THE ECOLOGY OF SYRMATICUS ELLIOTI SWINHOE

The investigation of syrmaticus ellioti was carried out in Zhejiang Province from May, 1983 to August, 1985 using the methods of walk follow and sample survey.Both the evergreen broad-leaf forest and the evergreen broad-leaf and coniferous mixed forest are the suitable habitats for Elliot's Pheasants. Intensity of, their activities, however, decreases remarkablely where the coverage of tree layer is less than 50%, and they can hardly be found where the coverage is less than 30%.In spring, the activity inten...
