陶寺遗址位于山西省襄汾县陶寺镇,距今4300~3900年。经过多次较大规模的发掘,陶寺遗址成为我国规模最大的、显现文明化程度最高的史前聚落遗址之一,也是研究中国史前至夏商时期城址都市化进程中的一个重要的里程碑式遗址。本文通过热电离质谱分析方法对陶寺遗址中晚期遗迹出土的21个个体人类牙釉质的锶同位素比值进行了测定。结果表明,这些人类牙釉质的锶同位素比值平均值是0.711374(2σ=0.000680,n=21)。与以前建立的遗址当地的锶同位素比值范围比较可知,有6个个体可能在遗址当地出生,由此推测本地个体占总数28.6%左右;还有15个个体牙釉质的锶同位素比值在遗址当地的锶同位素比值范围以外,表明这些个体可能在其他地区出生,推测外来者占总数的71.4%左右。由此可知,在陶寺文化中期至晚期的陶寺遗址的先民中,存在很高比例的外来移民。
Taosi site is located in Xiangfen County, Shanxi Province Tao Si, dating from 4300 to 3900 years. After many large-scale excavations, Taosi Site has become one of the largest prehistoric settlement sites in China with the highest degree of civilization. It is also an important milestone in the study of the urbanization of the site sites in China from prehistoric to Xia Dynasty . In this paper, the strontium isotope ratio of 21 individual human enamel unearthed in the middle and late stage of Taosi Site was determined by thermal ionization mass spectrometry. The results show that these human enamel strontium isotope ratio average 0.711374 (2σ = 0.000680, n = 21). Compared with the range of the local strontium isotope ratio of the ruins previously established, six individuals may be born locally on the site, suggesting that the local individuals account for about 28.6% of the total number of individuals; and the strontium isotope ratio of enamel of 15 individuals in the local Strontium isotope ratio outside the range, indicating that these individuals may be born in other areas, speculating that outsiders accounted for 71.4% of the total. It can be seen that there are a high proportion of immigrants among the ancestors of the Taosi Site in the middle and late Taozhai culture.
