摘要
对保安族208人(男105人,女103人)的52项体质特征进行了人体测量学研究。对保安族及其周围民族体质特征的差异进行了主成份分析,找出了民族间差异的主要表现。使用主成份得分(作为变量)进行聚类的方法,对保安族和周围民族体质特征的相像相异作了分析研究,保安族和东乡族,甘肃汉族和回族较为相像,和藏族,维吾尔族,蒙古族和陕西汉族较为相异。
Bonan nationality was measured in 105 adult males and 103 adult females in August, 1988. Items of 44 direct measurements and 8 indirect measurements and 48 indices were investigated.The measurements and indices of all individual were classified into different types according to the standards of Martin and Sailer (1957).Results can be summarized briefly as follows:The average stature is 1634mm (male) or 1537 (female). In stature type, the frequencies of short. medium short, medium and tall are nearly equal both in male and in female. According to three different indices, most of the head types belong to mesocephaly, hypsicephaly and me-triocephaly respectively both in male and infemale. Most of the facial types belong to leptopros-opy and hyperleptoprosopy both in male and in female. Most of the nasal types belong to lepto-rrhiny both in male and in female. Most of the hand types belong to mesocheir both in male and in female.The sexual difference presents more obviously in items of measurements than in items of indices.Principal components analysis (PCA) was made using anthropometric data of several na-tionalties or populations from northwest China. The characteristics used in PCA are head length, head preadth, minimum frontal breadth, facial breadth, bigonial breadth, physiognomic facial height, morphological facial height, nasal height, nasal breadth, mouth breadth (only in male) and stature. From the eigenvectors, we can conclude that PCI replesents size characters concerning the cephalo-facial breadth both in male and in female. PCII represents shape characters concerning the cephalo-facial breadth, length and height both in male and in female, and PCIII represents head length character in female.Cluster analysis was made using the scores of PCI, PCII and PCIII instead of original variables. Accumulated contribution of PCI, PCII, and PCIII readier up to 96% in meale and 93% in female. From the dendrogram of cluster analysis, Bonan is closes to Dongxiang, Hui, Han from Gansu, than to Mongol, Uygur, Tibetan and Han from Shaanxi Province.
