摘　　要：四川山鹧鸪（Arborophila rufipectus）是我国西南山地特有的珍稀濒危鸟类，迄今对其越冬栖息地的了解甚少。2013年1月和2014年1—2月，在四川老君山国家级自然保护区对其冬季栖息地特征进行了研究。野外共测定了48个利用样方和30个对照样方的特征参数。结果表明：四川山鹧鸪偏好选择海拔较低、坡度平缓、乔木盖度较小、竹子较矮、草本低矮稀疏、1.0 m层盖度较大、4.0～5.0 m层盖度较小、距小路和林缘较近的栖息地。此外，四川山鹧鸪还倾向于选择在距水源较近及地表落叶丰富的栖息地活动。安全与食物条件可能是影响四川山鹧鸪冬季栖息地选择的关键因素。Sichuan Partridge （Arborophila rufipectus） is an endangered species endemic to the mountains of Southwest China. So far, little information is known about its winter habitat. We studied the winter habitat characteristics of Sichuan Partridges at the Laojunshan National Nature Reserve in Sichuan Province, China in January, 2013 and from January to February, 2014. The habitat characteristics of totaling 48 plots used by the partridges and 30 control ones were measured. It was found that Sichuan Partridges preferred the habitats with lower altitude, gentle slope, small coverage of trees, short bamboos, low and lessdense herbs, large coverage of 1.0 m layer, small coverage of 4.0-5.0 m layers, and close to trails and forest edge. In addition, Sichuan Partridges also preferred the sites close to water resources and with abundant leaf litter. Security and food condition might be the key factors influencing winter habitat selection by the Sichuan Partridge.
