摘要
本文根据十九组颅骨测量资料研究了现代中国人颅骨测量特征及其地区性差异。平均值对比、指数对比和聚类分析结果显示中国人颅骨特征呈现明显的南北地区性差异。北方人较南方人具有更大的颅周长、眶宽、眶高、鼻高和上面高。从北部到南部,颅骨形态的变化规律是圆颅型比例下降,中颅型比例增加;狭面型比例下降,中面型比例增加;狭鼻型和高眶型比例下降,中鼻型和中眶型比例增加。作者据此提出了国人颅骨的南北两种类型并指出了这两种类型之间差异的逐步变化趋势。
The object of this study is to explore the characteristics of modern Chinese skulls and its variations among different geographical regions and nationalities.
The materials used in this study include the metric data of 19 groups of modern Chinese male skulls ranging from northeastern Changchun to southern Hainan island. The measurements taken in this study are 16. Three statistical techniques used to deal with the data are: means comparisons, indices comparisons and cluster analysis. The results are as follows:
1. Means comparisons show that the skulls of north Chinese have bigger values of cranial horizontal circumference, orbital height, orbital breadth, nasal height and upper facial height than those of South Chinese.
2. Indices comparisons indicate that from north to south, the percentages of brachycrany, leptorrhiny and hypsiconchy decrease; mesocrany, mesoprosopy, mesorrhiny and mesoconchy increase.
3. The result of cluster analysis shows all these groups were classified into two parts just according to geographical regions.
According to the results of the analysis of the skull data, it is proposed that modern Chinese should be divided into two types (north and south).
