西双版纳傣族头面部形态特征的年龄变化

摘要

采用体质人类学方法于2013年在云南省西双版纳调查了402例(男197例,女205例)云南傣族成人的22项头面部测量指标和15项观察指标,计算了12项头面部指数.结果表明:(1)傣族男女的口裂宽、上唇皮肤部高、容貌耳长,随年龄的增长呈线性上升趋势;傣族男女的唇高、红唇厚度,随年龄的增长呈线性下降趋势.(2)傣族男女的口指数、容貌耳指数值随年龄增长呈线性下降趋势.(3)傣族男女有蒙古褶率,眼裂倾斜度眼外角高于眼内角率呈线性下降趋势,耳垂圆形率、红唇薄唇率呈线性上升趋势.%The twenty-two head and facial physical characteristics and fifteen observed indicators on 402 Dai adults (197 males and 205 females)were investigated in Xishuangbanna city of Yunnan province,and calculated 12 head and facial indices. The results are as follows,(1)As age increases,the mouth breadth,upper lip skin height and physiognom?ic ear length linearly increase,but the lip height and thickness of lips linearly decline.(2)With increasing age,the oral index and physiognomic ear index linearly decrease.(3)As age increases,the Mongoloid fold rate linearly declines,the external angle direction of eyeslit linearly decreases,rounded lobes and thin lips linearly increase gradually.
