新疆托木尔峰自然保护区冬季北山羊昼间活动节律与时间分配

Winter Daily Activity Rhythm and Time Budget of Ibex(Capra ibex) in Tomur Protected Area,Xinjiang

2005年10～12月，在新疆托木尔峰自然保护区用直接观察法对193头次北山羊（Capraibex）的活动节律和时间分配进行了观察。结果表明，北山羊群冬季的活动规律性较强，呈现双峰型，2个高峰时段为08：00—08：30时和16：30～17：00时前后，活动频率分别为98．6％和93．3％。同时发现冬季其61％的活动时间用于采食，用于移动和站立的时间分别为19％和15％。这种活动节律可能与光照以及人类放牧干扰有关。
