摘　　要：目的了解四川凉山彝族头面部群体遗传学特征。方法用随机整群抽样法,调查313例(男性204例,女性109例)四川凉山彝族中学生9项遗传学指标。结果 (1)彝族有眦褶率、上眼睑有褶皱率、铲型门齿率、凸型鼻梁率、宽型鼻孔率、突型下颏率、有耳垂率、尖形发际率和卷发率分别为58.47%、85.94%、95.85%、2.87%、77.32%、4.15%、72.84%、37.70%和23.00%。(2)额头发际有性别差异。结论四川凉山彝族9项头面部群体遗传学特征与其他族群存在差异。Objective To identify the genetic characters of Yi＇s head-face in Liangshan of Sichuan.Methods Nine genetics indexes,including mongoloid fold,eyefold of the upper eyelid,front tooth type,nasal profile,nostril form,chin projection,lope type,hair point of the forehand and hair form were investigated for 313 middle school students（204 males and 109 females） in Yi by using cluster random sampling method.Results（1）The rate of Mongolia fold is 58.47%,the rate of eyefold of the upper eyelid is 85.94%,the rate of shove-shaped front tooth type is 95.85%,the rate of umbonate nasal profile is 2.87%,the rate of wide nostril is 77.32%,the rate of protruding chin is 4.15%,the rate of ear lope is 72.84%,the rate of pointed hair point on forehead is 37.70% and the rate of curly hair form is 23.00% in Yi.（2）Eight indexes showed no sexual difference except for the rate of point of the forehand.Conclusions There are differences between Yi and other nationalities in genetic characters of head-face.
