【摘要】 首次利用定量图像分析的方法研究野生大熊猫的取食行为 ,结果显示 :其取食行为存在固定的模式 ,这一模式是在其身体发育的过程中逐步形成的。到了老年 ,随着年龄的增大、牙齿的磨损和其他生理机能的衰退 ,这种模式逐渐解体。总的取食时间可以分为准备时间 (38 0 8% )、间歇时间 (5 13% )和吃的时间 (5 6 79% ) ,在取食时间总量不变的情况下 ,大熊猫通过 3种途径有效地增加日食量 ,即提高动作熟练程度、减少准备时间和减少间歇时间。更多还原

【Abstract】 It was the first time to analyze feeding behavior of giant pandas using video method,and the result showed that there was a fixed feeding pattern in the giant panda.Different individual had the similar feeding action and procedure when they acquire the same food.Comparing the behavioral data of one individual in different physiological phases and different individuals,the author found that accompanying with the physiological development of panda and the accumulation of feeding experiences thereafter,the feeding behavior became steady,the actions became adept and the feeding speed increased.However,the feeding behavior became instability and the feeding speed decreased when pandas were old,their teeth were frayed and their physiological function declined.The total feeding\|time can be divided into three parts defined as time for intervals (5 13%),time for preparing (38 08%) and time for eating (56 79%).Panda could increase the daily intake by three effective ways,increasing action proficiency,decreasing the time for preparing and intervals,when the total feeding\|time was fixed.更多还原
