摘要: 对小兴安岭南部低山丘陵地区狍冬季卧息地的选择性进行了研究。Jacobs法和资源选择函数均表明:昼间狍偏好位于阳坡的针阔混交林,对灌木、下层植被覆盖度及雪深具有选择性; 夜间狍的卧息地多位于阴坡的针阔混交林和阔叶混交林,对乔木和下层植被覆盖度具有选择性。狍的昼间和夜间卧息地在植被类型、坡向、乔木冠幅、灌木高度、1 m以下植被覆盖度、1~2.5 m植被覆盖度、隐蔽级、卧息地长和卧息地宽上差异显著(P<0.05)。与夜间卧息地相比,狍昼间偏爱的卧息地具有乔木冠幅较大、灌木较矮、林下植被覆盖度较高、隐蔽程度较好、卧息地长度和宽度较小的特征。

Abstract: This paper studied the selection of winter bed-sites by Capreolus capreolus in the low mountain areas of southern Xiaoxing’anling Mountains, Northeast China. Both Jocabs’ and resources selection functions revealed that C. capreolus preferred the coniferous and broad-leaved mixed forest on sunny slope, referring with shrub height, ground cover and snow depth in day-time, and the coniferous and broad-leaved mixed forest and broad-leaved mixed forest on shady slope, considering arbor crown breadth and ground cover in nighttime. There were significant differences in the vegetation type, slope direction, crown breadth, shrub height, ground covers of <1 m and 1-2.5 m, hiding degree, and length and width of the winter bed-sites in daytime and nighttime. Compared with nighttime, the winter bed-site in daytime preferred by C. capreolus had the characteristics of larger arbor crown breadth, lower shrub height, denser ground cover, more concealment, and less length and width.
