传统圈养和半自然散放环境亚成年大熊猫的行为差异

2001年7月20日至8月20日，在四川卧龙自然保护区中国保护大熊猫研究中心，采用连续观察法记录和分析了传统圈养和半自然散放环境下亚成年大熊猫(分别为3和9只)的几种行为的持续时间和发生次数。传统圈养环境亚成年大熊猫探究行为的持续时间、标记行为的频次显著多于半自然散放环境下的个体；刻板行为的持续时间有增加的趋势，但无显著差异。刻板行为的持续时间与标记行为的频次和探究行为的持续时间均呈显著正相关。表明圈养环境的改善有助于亚成年大熊猫探究和标记行为的明显减少。

Behavioral Difference of Sub-adult Giant Pandas (Ailuropoda melanoleuca) in Traditional and Semi-natural Enclosures

The behaviors of sub-adult giant pandas (Ailuropoda melanoleuca) under two different captive conditions (3 pandas in traditional enclosures and 9 in semi-natural enclosures) were studied in China Conservation and Research Center for the Giant Panda,Wolong Nature Reserve from Jul.to Aug.2001.The duration and the frequency of behaviors were recorded by continuous observation.The findings demonstrate that sub-adults in traditional enclosures spent more time in investigating behavior and marking behavior than those in semi-natural enclosures,and stereotypic behavior of sub-adults in traditional enclosures had an increasing trend yet the difference didnt reach statistic significance.The duration of stereotypic behavior was significantly and positively correlated with the frequency of marking behavior and the duration of investigating behavior.These results indicate that the improvement of captive conditions can help to reduce the time sub-adult giant pandas spend on investigating behavior and the frequency of marking behavior.
