上海郊区人群的体质特征和遗传关系

本项研究收集了上海郊区的 13个具有明显方言差异的人群的各类人类遗传学数据 5 3项进行聚类分析 ,发现黄浦江以东的人群相对较纯 ,而黄浦江以西的则较混杂 ,两组群体都分别可以聚成较远的 3类。由此认为上海郊区的人群大致有 3种起源 ,上海奉贤区金汇镇和闵行区马桥镇为代表的居民与南方土著民族较近 ,崇明县、嘉定区、浦东新区和南汇区的居民与北方民族较近 ,而奉贤区的头桥镇、金山区、青浦区的朱家角和商榻、松江区天马山等地的居民又是另一类。这与历史记载他们的不同来源有关。

PHYSICAL CONSTITUTION AND GENETIC RELATIONSHIP OF SHANGHAI SUBURBIA

Owning to the special location of Shanghai, almost every large population migration throughout the history of China left traces in Shanghai. We collected data of Shanghai from 13 populations which have obvious differences in terms of dialects. The cluster analysis on the data showed that the populations to the east of Huangpu River are relatively pure while the populations to the west of Huangpu River are relatively mingled. Both the populations can be further clustered to a third one. This suggests that the populations in Shanghai suburb may have 3 sources. (Most of the inhabitants of Jinhui town in west Fengxian County and the Maqiao town of Minhang area are natives of South China. The inhabitants of Chongming County, Jiading area Pudong area and Nanhui County are the immigrants from North China, those of Touqiao town in Fengxian County, Jinshan area,Zhujiajiao and Shangta of Qingpu area, Tianmashan of Songjiang area are the immigrates from the west.) These conclusions are generally consistent to the historical record, except for some minor deviations.
