巴尔虎人头面部形态特征的年龄变化

Variation of Morphological Characteristics in Head and Face With the Increasing Age of Barags

为研究巴尔虎人头面部形态特征随年龄增长而变化的规律,按照国际学术界规定方法,在内蒙古呼伦贝尔市新巴尔虎左旗测量了400例(男196例、女204例)巴尔虎成年人38项头面部指标,并计算了12项头面部体质指数,对巴尔虎人头面部形态特征的年龄变化进行了初步分析.结果表明(1)随年龄增长,巴尔虎人蒙古褶率下降,眼裂渐趋水平,鼻孔最大径趋于水平,眼色变浅,上唇皮肤部变高,红唇变薄.(2)巴尔虎人鼻宽、口裂宽、上唇皮肤部高度、容貌耳长、容貌耳宽与年龄呈正相关;眼外角间宽、唇高、红唇厚度、耳上头高与年龄呈负相关;头长、面宽、下颌角间宽、眼内角间宽、鼻长、鼻深、头围、面颊皮褶8项指标与年龄无相关.(3)形态面、头面高、鼻指数与年龄呈正相关,头长高、口指数与年龄呈负相关.说明巴尔虎人多数骨性头面部指标随年龄增长变化不大,而多数软组织指标随年龄增长变化明显.

In order to study the rules of the variation of head - face morphological characters with the increaseing age, thirty-eight indices of head-face characteristics on 400 individuals of Barags. （196 males, 204 females）were investigated in Xin Barag Left Banner, Hailaer, Mongolia. Twelve physical indices were calculated. Preliminary analysis were carried out on the variation of head-face characteristics with increasing age. The results show： （1） With increasing age, Barags themongoloid fold rate decreased, the direction of eyeslits tended to level, the maximum sizeof the nostril tended to level, eye color become shallow, the height of narrow partof the upper lip raised, and lip thickness decreased. （2） Correlation analysis shows that nose breadth, mouth breadth, upper lip height, physiognomic ear length and physiognomic ear breadth were positively correlated with age; In contrast, external binocular breadth, lip height, thickness of lips, auricular high were negatively correlated with age. And head length, face wide, bigonia 1 diameter, interocular breadth, nose length, nose depth, head circumference, face skinfold showed no correlation with age. （3）Morphological facial height, vertical eephalo-facial index and height-breadth index of nose were positively correlated with age. Length-height index of head and lip index were negatively correlated with age. These indicate that with the increasing age, most of synostosis of Barags head- face morphological didn＇t change obviously, but some soft organizations indices changed significantly.
