摘　　要：2008年6月至2009年5月,在白马雪山国家级自然保护区(27°24'-27°37'N,98°22'-99°25'E)南端的响古箐(27°37'N,99°22'E),采用15分钟的扫描取样法对一群数量约480只的超大滇金丝猴(Rhinopithecus bieti)群日活动节律进行了研究.研究发现,滇金丝猴群全年的日活动节律,表现为上午07∶00-11∶00和下午16∶00-18∶00各出现一个明显的取食高峰,在12∶00-14∶00期间全群进入白天的休息阶段;移动也在上午和下午各出现一个高峰;其他类型活动没有明显的起伏变化.不同季节间,日活动节律存在一定差异:春季和冬季,滇金丝猴群上午的取食高峰出现在11∶00,夏季和秋季的取食高峰出现在08∶00;春季,滇金丝猴群下午的移动高峰从15∶00-19∶00;夏季,它们下午的移动高峰出现在15∶00-16∶00;滇金丝猴群在秋季表现出两个午休高峰时段12∶00和13∶00,其他季节午休高峰仅出现在13∶00.可见,响古箐超大滇金丝猴群的日活动节律表现为具有明显的取食、移动和休息高峰.它们的日活动节律受群体大小、季节性食物、消化机理和周围环境温度等因素的影响.An over-large group of Yunnan snub-nosed monkeys （Rhinopithecus bieti） at Xiangguqing （27 °37＇N, 99°22＇E） was investigated on its daily activity rhythm in B aimaxueshan National Nature Reserve （27°24＇- 27°37＇ N,98°22＇ -99°25＇E） , Yunnan Province from June 2008 to May 2009, via 15 min scan sampling method. The number of monkey group increased to 480 in 2008. The results showed that there were two feeding peaks of the studied group of R. bieti presented during 07：00-11 ： 00 and 16： 00-18： 00, with a midday resting peak 12： 00-14： 00 during whole-year diurnal cycle. Seasonality influenced daily activity rhythm of the group. Feeding peak was at 11：00 in spring and winter, and 08：00 in summer and autumn. Moving peak of the monkey group oppeared from 15：00 to 19：00 p. m in spring, but from 15：00 to 16：00 in summer. There were two resting peaks which presented atl2：00 and 13：00 in autumn; however, in other seasons these was only one resting peak at 13：00. In summary, the daily activity rhythm of this over-large monkey group showed markedly feeding peak, moving peak and resting peak. The daily activity rhythm was influenced by group size, seasonal foods, digestion mechanism and environment temperature.
