[摘要] 目的 了解拉萨世居藏族男性指纹特征的基础参数。方法 2019年3—6月选取拉萨市高校藏族男青年135名,采用掌指紋按捺盒选取符合的肤纹图做指纹样本的参数,使用ACD图像分析软件局部放大后观察。 结果 世居藏族男青年指纹特征为W(51.3%)>U(22.6%)>R(17.1%)>A(9.0%),右手R多于左手(P<0.05),右手U少于左手(P<0.05)。各指同型组合频率为拇指51.9%、示指50.4%、中指43.7%、环指59.3%、小指30.4%。左右两侧拇指、指纹嵴线数差异有统计学意义(P<0.05)。结论 拉萨世居藏族男青年纹型特征斗型纹频率最高,箕形纹次之,弓形纹频率最低。

[Abstract] Objective To understand the basic parameters of fingerprint characteristics of Tibetan males in the Lhasa. Methods A total of 135 Tibetan young men from colleges and universities in Lhasa from March to June 2019 were selected. The palm skin fingerprints were used to select the matching skin texture map as the fingerprint sample parameters, and the samples were magnified with ACD image analysis software and observed. Results The fingerprint characteristics of Shiju Tibetan young men were W (51.3%)> U (22.6%)> R (17.1%)> A (9.0%). The right hand R was more than the left hand (P<0.05); and the right hand U was more than the left hand(P<0.05). The frequency of the same type combination of the fingers was 51.9% of the thumb, 50.4% of the index finger, 43.7% of the middle finger, 59.3% of the ring finger, and 30.4% of the little finger. There were differences statistically significant in the number of thumbs and fingerprints on the left and right sides (P<0.05). Conclusion In the Lhasa, the young Tibetan male pattern features the highest pattern frequency, followed by the striated pattern and the lowest frequency of arch pattern.

皮纹是人类体质的生物学特征之一,是重要的遗传性状,它具有个体特异性,终生不变性和世代遗传性,因而在人类学[1],遗传学[2],心理学[3]、临床诊断[4]和法医学[5]等领域都得到广泛应用。指纹属于形态学的一部分,是由手指末端的皮嵴与皮沟共同构成的图形。指纹在胚胎第19周基本完成发育,此后在正常情况下终身不再改变,是个体鉴别的重要表标志。指纹是皮纹的一部分,专门研究指端纹型的,较皮纹学范围局限,但应用范围更加广泛。
藏族是中国的少数民族之一,主要是分布在西藏自治区和青海、甘肃、四川、云南等省区。藏族的体质特征说法不一,有学者认为与蒙古人种中的东亚种族类型最接近,也有学者认为靠近蒙古人种的北亚型。从皮纹学角度看,藏族跖纹和指纹均呈现出蒙古人种的一般特征。拉萨藏族生活在平均3 500 m海拔以上,拉萨世居藏族男青年进行掌指纹调查研究较少,2019年3—6月该研究选取拉萨市高校藏族男青年135名,1 350个手指,可为人类学等相关研究提供基础资料,报道如下。
