目的 研究大熊猫的四季行为特征，为更有效地管护和饲养大熊猫提供参考。 方法 2017年10月—2018年10月，采用目标动物取样法对重庆动物园4只大熊猫（Ailuropoda melanoleuca）按年龄分为成年组（5.5~20岁）与老年组（20岁以上）进行1年的行为研究。 结果 成年和老年大熊猫主要行为是休息行为（61.33%±3.88%）和摄食行为（22.89%±4.5%）。不同年龄大熊猫行为差异显著，在老年组中，修饰、休息、过分修饰、刻板行为显著高于成年组，而摄食、活动行为方面显著低于成年组。重庆动物园大熊猫四季行为除修饰行为四季差异不显著外，摄食、活动、休息、过分修饰、刻板行为、其他行为四季间差异显著，夏季摄食行为在四季中最低。 结论 摄食行为与季节有关，夏季气候炎热，摄食行为最短；摄食行为与休息行为呈负相关，即摄食行为越长，休息行为越短。增加丰容物可增加活动行为，对于老年大熊猫，提供食物和气味丰容比提供环境方面的丰容更有效。

Objectives The characteristics of seasonal behavior of giant pandas were studied to provide reference for managing and farming giant pandas more effectively. Methods A target animal sampling method was used to conduct one-year study on the behavior of four giant pandas (Ailuropoda melanoleuca) divided by age into an adult group (5.5-20 years old) and an elderly group (over 20 years old) at Chongqing Zoo from October 2017 to October 2018. Results The main difference in behavior of the adult and the elderly giant pandas was the behavior of resting (61.33% ± 3.88%) and the behavior of feeding (22.89% ± 4.5%). There were significant differences in behavior among giant pandas of different ages. In the elderly group, grooming, resting, excessive grooming, and stereotyped behavior was significantly higher than that in the adult group, while the behavior of feeding and activity was significantly lower than that in the adult group. There was significant difference in the behavior of giant pandas in Chongqing Zoo during the four seasons, except for their modification behavior. There was significant difference in feeding, activity, rest, excessive modification, stereotyped behavior, and other behaviors among the four seasons, with feeding behavior in summer being the lowest among the four seasons. Conclusions The feeding behavior was related to the season, with the summer climate being hot and the feeding behavior being the shortest. There was a negative correlation between feeding behavior and resting behavior, indicating that the longer the feeding behavior, the shorter the resting behavior. Increasing the abundances can enhance the behavior of activity, and providing the abundance of food and odor is more effective than providing environmental abundances for elderly giant pandas.
