摘　　要：为研究环境温度对动物冬眠的影响,在实验室不同环境温度下((5±2)℃,(15±2)℃,(25±2)℃)用植入式半导体元件记录了达乌尔黄鼠冬季的体温,监测了冬眠模式及能量消耗。结果显示环境温度不同时,达乌尔黄鼠冬眠的模式和能量消耗均有显著差异。在5℃下,动物均表现为深冬眠型;15℃下,动物表现为深冬眠型和少冬眠型;25℃环境下动物表现为较多少冬眠型和少量不冬眠型。在5、15和25℃冬眠期间总能量消耗分别为(3 722±217.82)kJ,(18 907±2 895.07)kJ,(30 542±2 146.40)kJ,差异显著(F(2,22)=45.198,P=0<0.01)。提示在冬眠动物的冬眠季节,从能量学角度来看,高的环境温度并不利于动物的越冬。In order to research the inflience of the ambient temperature on animals during hibernation,we used iButtons to monitor the body temperatures in winter,hibernation patterns and energy consumption of Daurian ground squirrels under different ambient temperature（（5±2）℃,（15±2）℃,（25±2）℃）in laboratory.Under different ambient temperature,the hibernation patterns and energy consumption in Daurian ground squirrels were significantly diversified.At 5℃,animals all showed deep hibernation.At 15℃,both deep hibernation and short hibernation were showed.At 25℃,the more deep hibernation and the lesss no hibernation were behaved.When the temperatuer was at 5℃,15℃and25℃during hibernation,the total energy consumption was respectively（3 722±217.82）kJ,（18 907±2 895.07）kJ and（30 542±2 146.40）kJ.The diversity was significant（F（2,22）=45.198,P=00.01）.From the view of energetics,the high ambient temperature is not conducive to spend winter for hibernation animals in hibernation season.
