摘　　要：观察了小兴安岭林区秋冬季节松鼠日活动节律。松鼠秋季的日活动节律为双峰型 ,冬季的日活动节律为单峰型 ,秋季日活动时间为 (9 1 0± 1 0 3 )h ,其中取食时间所占的比率为 85 5 0 % ,冬季日活动时间为 (4 62± 0 5 1 )h,取食时间所占的比率为 88 2 5 % ,两季节间的日活动时间存在显著的季节差异(t=8 1 7,P <0 0 5 )。松鼠日活动节律和活动时数受日照时数、温度。The daily activity rhythms of 8 Red squirrels (Sciurus vulgaris) was preliminarily observed by means of a telescope in the Lesser Xing′an Mountains Forest Region in the autumn of 1999 and winter of 2000. On a seasonal basis, Red squirrels displayed two distinct daily activity rhythms; a bimodal pattern of activity in the autumn, and a unimodal pattern in the winter. In the autumn, the total duration of daily activity was (9 10±1 03)h in average and foraging took 85 50% of total daily activity. Total daily activity time was(4 62±0 51 )h in the winter, and foraging time took 88 25% of total daily activity. There was a significant difference in total daily activity time between autumn and winter( t =8 17, P <0 05). Based on the seasonal pattern of activity, the daily activity rhythm of Red squirrels was affected by the day\|length, temperature, food availability, and the degree of human disturbance.
