摘　　要：2010年4月18日-28日在图牧吉保护区对大鸨的繁殖前期行为规律进行了观察。繁殖前期的时间分配中觅食行为29.56%,静栖行为24.31%,游走行为21.92%,警戒行为11.31%,理羽行为9.82%,求偶行为2.48%,其余行为比较少;日节律显示：觅食行为在一天中出现两次高峰,即6：00-7：00和16：00-17：00之间,而在12：00左右出现低谷;静栖行为和理羽行为则在早晨和晚上处于低谷,在12：00左右,达到峰值;游走行为在12：00左右达到低谷,在其他时间趋于稳定;警戒行为在一天中基本趋于稳定。求偶行为只出现在早晨和傍晚之间有两个间断峰值,无规律性。雌雄大鸨在觅食行为（p=0.021）和求偶行为（p=0.019）时间分配上存在显著性差异。其余行为时间分配上不存在显著性差异。The rhythm of behaviors in pre-reproductive period was observed at April 18-28,2010 in Tumuji National Nature Reserve,Inner Mongolia.The time budget of various behaviors in pre-reproductive stage was feeding（29.56%）,resting（24.31%）,walking（21.92%）,alert（11.31%）,preening（9.82%）,courtship（2.48%）,and the else behaviors was rare.The behavior rhythm of Great Bustard showed that feeding in one day appeared twice peaks at 6：00~7：00 and 16：00~17：00,and the trough occurred during 12：00.Resting and preening appeared the trough in the morning and evening,however,reached the peak at the middle of a day.Walking only reached the trough at the middle of a day and then keeped steady in other times.Alert tended to keep steady in a day.Courtship only had two discontinuous peaks and non-regularity.significant difference was found for female and male between feeding（p=0.02） and courtship（p=0.019）.There was no significant difference in else behaviors.
