摘　　要：在个体识别的基础上,采用行为取样法进行观察和连续记录法进行记录,对一个人工投食的滇金丝猴Rhi-nopithecus bieti群中的全雄单元在猴群移动时的空间结构进行研究。结果表明:全雄单元在和其他一雄多雌单元组成一个大群一起移动时,全雄单元往往走在整个大群的最前端;在全雄单元内部,成年个体往往又是走在全雄单元的最前端。这种空间结构使全雄单元起着决定并且带领整个大群移动方向的作用,并且使全雄单元中个体可以优先比其他一雄多雌单元中个体采食到优质的食物。Based on the individual identification, the spatial structure of a provisioned troop of Yunnan Rhinopithecus bieti was investigated by behaviour sampling and continuous recording methods. The results show that when the allmale unit （AMU） and the other one -male units （OMU） as a whole moved forward, the AMU always walked in the front of the troop and the male adults of the AMU usually walked in the front of the AMU. This spatial pattern makes the AMU decide the troop＇ s moving direction. The ecological function of spatial structure was to allow the AMU member to get high quality food.
