摘　　要：在云南省丽江市宁蒗县永宁乡中学对250例摩梭人中学生(男125例,女125例)的7项不对称行为特征(扣手、利手、叠臂、叠腿、利足、起步及利眼)进行了研究.结果显示:(1)摩梭人的扣手、利手、叠臂、叠腿、利足、起步和利眼左型率分别为29.6%、6.4%、49.2%、20.4%、3.2%、41.6%和32.4%;左型率均低于右型率;仅扣手出现率性别间差异具有统计学意义;(2)在中国少数民族中,摩梭人扣手左型率和利足左型率处于较低水平,利手、叠臂、叠腿、起步类型和优势眼左型率均处于中等水平;(3)摩梭人利足分别与扣手、利手、叠臂两两相关,叠腿和利眼两两相关;(4)聚类分析结果显示,摩梭人与云南蒙古族距离最为接近,与内蒙古蒙古族诸族群距离较远.A sample of 250 middle school students（125 males, 125 females） of Mosuo from Ninglang Yongning middle school in Lijiang of Yunnan province was investigated on 7 Behavioral Traits of Lateral Functional Dominance （hand clasping, handedness,arm folding, leg folding, foot preference,stride type, eye preference）. The results were as follows. （1）The frequencies of Lefttype of hand clasping, handedness, arm folding, leg folding, foot preference, stride type and eye preference were 29. 6%, 6. 4%,49. 2%,20. 4%, 3. 2%, 41. 6% and 32. 4%, respectively; The frequencies of Left-type of were lower than that of Right-type;Significant sexual difference was only found in the frequency of hand clasping. （2）Among ethnic minorities of China,the frequencies of Left-type of hand clasping and foot preference were on low level,and that of handedness, arm folding,leg folding,stride type and eye preference were on average level. （3）The related indexes of 7 Behavioral Traits of Lateral Functional Dominance of Mosuo were between foot preference and hand clasping,handedness,arm folding, respectively;another one was between leg folding and eye preference. （4）The result of dendrogram of cluster analysis showed that Mosuo was close to Mongolian in Yunnan,was far from many Mongolian groups in Inner Mongolia.
