摘　　要：在广西弄岗森林动态监测样地及其周边区域(总面积70 hm^2)共布设了35台红外相机,对分布其中的赤腹松鼠Callosciurus erythraeus进行了为期1年的监测,并采用活动强度指数对其活动节律和时间分配进行分析,探讨赤腹松鼠对喀斯特石山生境的适应策略。结果表明:不同时间段赤腹松鼠的活动节律存在极显著差异(t=7.414,df=13,P<0.01),活动模式呈典型的双峰型,活动峰值出现在7:00-8:00和17:00-18:00。赤腹松鼠日活动主要以移动(69.82%)和觅食(21.72%)为主,时间分配在不同月份间存在极显著差异(t=8.519,df=11,P<0.01),但在旱雨季间不存在显著差异(Z=-1.218,P=0.20)。最适的活动温度范围为14~28℃,偏向于接近当月平均气温的时间段活动。Data on the activity rhythms and time budgets of Red-bellied Squirrels(Callosciurus erythralus) were collected by infrared cameras between August 2012 and July 2013 in the Forest Dynamics Plot and its surrounding area(Total area 70 ha) in Nonggang National Nature Reserve. We used a relative activity intensity index to analyze the activity rhythms and time budgets of Red-bellied Squirrel, and explore the adaptation strategy to Karst habitat. The results showed that activity rhythm varied significantly over the course of the day(t=7.414, df=13, P=0.003), with two activities peak at 7:00-8:00 and 17:00-18:00. The moving(69.82%) and foraging(21.72%) activity were Red-bellied Squirrel’s mainly behavior. There were significant differences in monthly time budget(t=8.519, df=11, P<0.01), but was no significant difference according to seasons(Z=-1.218, P=0.20). The optimal activities temperature of Red-bellied Squirrels was close to the average temperature in every month, and the activity temperature ranged from 14℃ to 28℃.
