Abstract: Diurnal time budgets and activity rhythms of 10 Hainan eld's deer ( Cervus eldi hainanus) fawns were recorded using instantaneous scan sampling in Ganzaling Nature Reserve, Hainan Province, February 20 - April 6 , 2003. Feeding, resting and ruminating made up the majority of diurnal activity time. Time penned deer spent feeding , resting , ruminating , standing and moving differed ( P < 0.01) from that of semi-free fawns ; semi2free fawns spent more time feeding and moving than penned fawns , and less time resting , standing and ruminating. Under penned conditions, peaks of feeding were recorded at 09:00-10:00, 11:00-12:00 and 16:00-18:00, and peaks of resting at 10:00-11:00 and 13:00 - 16:00. Under semi-free conditions , no distinct peaks of feeding were observed , fawns spent much time on searching and handling food , the peak of resting was found after 14:00.

摘要： 2003 年2 月至4 月间, 在海南甘什岭自然保护区采用瞬时扫描取样法对10 头海南坡鹿幼体昼间行为时间分配和活动节律进行了初步研究。结果表明: 坡鹿幼体昼间行为时间分配中摄食、卧息和反刍占有较大的比例;人工圈养和半散放条件下摄食、卧息、反刍、站立和运动行为的昼间时间分配差异性显著( P < 0.01), 半散放条件下幼鹿每天用于摄食和运动的时间比人工圈养的多, 而用于卧息、反刍和站立的时间较少, 其余行为时间比较接近; 在昼间活动节律方面, 圈养条件下摄食有3 个高峰期(09:00～10:00, 11:00～12:00, 16:00～18:00) , 卧息有2 个高峰期(10:00～11:00, 13:00～16: 00) ; 半散放条件下没有明显的摄食高峰期, 主要原因是大部分时间花费在食物的搜索和处理上, 而其卧息高峰出现在14:00 以后。
