为了研究城市环境中赤腹松鼠的活动节律,试验采用目标动物取样法和扫描动物取样法对赤腹松鼠的行为数据进行记录。结果表明:春季赤腹松鼠活动节律为昼行型动物,为晨昏双高峰型,活动高峰出现在07:00—09:00和15:00—18:00 2个时间段,各行为在不同的时间段存在极显著差异(P<0.01);行为节律以搜索行为为主,占日活动行为时间分配的比例为83.50%,平均日活动速率为v=3.42 m/min。赤腹松鼠的行为节律和日活动距离受天气状况、日照时间、温度和人为干扰等因素的影响。
In order to study the activity rhythm of red squirrel in urban environment, the behavioral data of the red squirrel were recorded by the target animal sampling method and the scanning animal sampling method. The results showed that the circadian rhythms of the red squirrel in spring were diurnal-type animals and double-peaked patterns at morning twilight. The peak of activity appeared in two time periods of 07: 00-09: 00 and 15: 00-18: 00. The behaviors were different at different times (P <0.01). The behavioral rhythm mainly consisted of search behavior, accounting for 83.50% of the total daily activities and the average daily activity rate was 3.42 m / min. Behavioral rhythms and daily activities of the red squirrel are affected by weather conditions, sunshine duration, temperature and human disturbance.
