摘　　要：在四川、云南和西藏共调查藏缅语族未识别民族1222例成人(男性576例,女性646例)的头面部与体部指标,并计算了体质指数与分型.结果如下:①藏缅语族未识别民族男性和女性的上眼睑皱褶率分别为71.2%和72.7%,男性和女性的蒙古褶率分别为31.8%和29.6%.藏缅语族未识别民族的鼻根高度以中等型为主,鼻背侧面观以直型为主,鼻孔最大径位置以倾斜居多,耳垂类型以圆形为主.②指数分型结果表明,男性以中头型、高头型、阔头型、中面型、中鼻型、长躯干型、中腿型、中胸型、宽肩型、宽骨盆型率最高,女性以圆头型、高头型、阔头型、中面型、中鼻型、中腿型、宽胸型、宽肩型、宽骨盆型率最高.③聚类分析结果表明,藏缅语族未识别民族与珞巴族、白族和纳西族比较接近.主成分分析结果显示,藏缅语族未识别民族的身高较高,头长值较大,鼻宽和口裂宽值较小.1222 individuals(576 males and 646 females)of Tibeto-Burman unidentified ethnic groups from Sichuan,Yunnan and Tibet were selected as subjects for the measurement of cephalo-facial and body indicators.The physical indexes and corresponding classification were determined as well.The results were as follows:①The eyefold rate of the upper eyelid in males and females was 71.2%and 72.7%,respectively,while the rate of Mongoloid fold was 31.8%and 29.6%in males and females,respectively.In the Tibeto-Burman unidentified ethnic groups,the nasal root height was mainly middle and its profile was basically straight.Plus,the maximal diameter of nostrils was mostly oblique,and the lobe type was depicted as round.②The physical features of males were classified as mesocephaly,hypsicephalic,tapeinocephalic,mesoprosopy,mesorrhiny,long trunk,mesatiskelic type,medium chest circumference,broad shoulder breadth and broad distance between iliac crests.However,in case of females,their features were considered as brachycephaly,hypsicephalic,tapeinocephalic,mesoprosopy,mesorrhiny,mesatiskelic type,broad chest circumference,broad shoulder breadth and broad distance between iliac crests.③The cluster analysis demonstrated that the physical characteristics of the Tibeto-Burman unidentified ethnic groups were closer to those of Lhoba,Bai and Naxi.The principal component analysis illustrated that the Tibeto-Burman unidentified ethnic groups were predicted to have high stature,long head length,small nose breadth and mouth breadth.
