我国23个群体体质的聚类分析与主成分分析

CLUSTER ANALYSIS AND PRINCIPAL COMPONENT ANALYSIS ON THE PHYSICAL CHARACTERS OF 23 POPULATIONS IN CHINA

作者选取１３项指标（头长、头宽、额最小宽、面宽、形态面高、鼻宽、鼻高、口裂宽、两眼内宽、身高、坐高、肩宽、骨盆宽）对我国２３个群体体质特征进行了聚类分析与主成分分析。研究结果显示：２３个群体可分为南方组、北方组（含两个小组）和中间类群组。南方组与北方组的体质区别主要为体部的长度、宽度的差异。北方组各群体之间头面部指标值差异较大。

Cluster analysis and principal component analysis of the physical characters of 23 populations in China with 13 measurements, including maximum head length, maximum head breadth, minimum frontal breadth, bizygomatic breadth, morphological facial heigth, nose breadth, nose heigth, mouth breadth, interocular breadth, stature, sitting height, breadth of shoulder and distance between iliac crests are made. The results show that the 23 populations can be divided into three groups: the south group, the north group and the group of middle type. The differences between south group and north group are principally in the lenghth and breadth of body. There are significant differences in cranio facial measurements among the north populations. While the cranio facial measurements of the south populations are comparatively close.
