以云南横断山区的高黎贡山、怒山和云岭等重要山脉的7 个山系作为样区，进行小型兽类的垂直分布调查并参考有关资料，采用不同山系样区各垂直带小型兽类物种多样性指数的平均值作为指标，对横断山区小型兽类的地理分布趋势、规律和相关影响因素进行了研究。结果表明：小型兽类物种多样性的地理分布趋势是由南向北，由西向东呈递减的趋势。与此趋势变化密切相关的主要因素是纬度的影响，其次是水湿条件，另外还与小型兽类的密度，物种丰富度、地理环境(坡向)和垂直带的影响等因素有关。此外，对横断山区不同区域小兽物种密度高峰问题作了分析和讨论。

The vertical distribution of small mammals was investigated in seven important mountain ranges of the Hengduan Mountains in Yunnan Province, such as Mt.Gaoligong and Mt.Yunling. The geographical distribution trends, rules and correlated variables were analyzed, based on the mean diversity indices of small mammals in the vertical zones of these ranges. The results demonstrated that the species diversity index decreased gradually from the south to the north and from the west to the east. The most important variables were latitude and rainfall. In addition, the peak of small mammals’density was analyzed and discussed in those areas.
