摘要
2003、2004年7-8月,采用目标取样法对青藏公路沿线藏羚羊（238群）、藏野驴（22群）和藏原羚（145群）不同行为的时间分配及活动频次进行观察,并分析各种行为与种群大小之间的相关关系。结果表明：取食行为是藏羚羊、藏野驴和藏原羚最主要的活动,其次是移动和站立行为。藏原羚取食和警戒行为持续的时间均显著多于藏羚羊和藏野驴;藏野驴修饰行为持续的时间极显著多于藏原羚和藏羚羊;而藏原羚的各种行为（除修饰行为）发生的频次均极显著高于藏羚羊和藏野驴。相关性分析表明,3种动物站立行为持续的时间和发生的频次均与种群大小呈明显的相关,说明3种野生动物采取不同的行为对策以适应当地的环境。
In July and August of 2003 and 2004, time budget and behavior frequency for the Tibetan antelope （Pantholops hodgsoni, 238 groups）, Kiang （Equus kiang, 22 groups） and Tibetan gazelle （Procapra picticaudata, 145 groups） distributed along Qinghai-Tibetan highway were observed by using focal animal sampling method and the relationship between their population number and behaviors was analyzed. The results showed that Tibetan antelope, Kiang and Tibetan gazelle spent most of time on their feeding and moving behaviors. The feeding and alerting time of Tibetan gazelle were significantly longer than those of Tibetan antelope and Kiang （P〈0. 05）, while the grooming time of Kiang was higher than those of Tibetan gazelle and antelope （P〈0.01）. Besides, the frequencies of all behaviors except of grooming for gazelle were much higher than those for antelope and Kiang （P〈0.01）. Meanwhile, the time and frequency of standing behavior for three kinds of animals were obviously related to their population number, which meant that these kinds of animals applied different behaviorally strategies to adapt to the environment.
