公元前2千纪下半叶,以蒙古人种、粟作农业(包括粟和黍)、彩陶等为特征的东方人群已到达新疆中部,并与安德罗诺沃文化等西方文明发生碰撞、交流甚至融合.然而,受益于新的考古发现,以粟黍为代表的东方文化要素在公元前3千纪~前2千纪时已传播至哈萨克斯坦、希腊、意大利等地.作为文化传播十字路口的帕米尔高原,其人群何时开始食用粟黍,东西方文化交流是否存在更早的迹象,尚缺乏佐证.为此,本文通过对新疆下坂地墓地青铜时代(公元前1500~前600年)出土的人骨进行C,N稳定同位素分析,发现下坂地墓地先民的食物结构,虽以C_3类的动物蛋白为主,但也不乏少许C_4类,在个别个体中,C_4类甚至占较大比例.结合考古资料,研究结果显示:先民的主要生活方式为畜牧或半游牧业,但麦作及粟作农业也是其不可或缺的一环.下坂地墓地的部分先民可能已开始食用粟类作物,这暗示了东方文化因素在帕米尔高原东端,即新疆西南部出现的时间可早至公元前1500年前后.
In the second half of the second millennium BC, the eastern population characterized by the Mongol race, millet agriculture (including millet and millet) and painted pottery has reached the central part of Xinjiang and collided with western civilization such as Andronov’s culture. Exchange or even integration.However, benefiting from the new archaeological findings, the oriental elements represented by millet spread to Kazakhstan, Greece, Italy and other places from the third millennium BC to the second millennium BC As a crossroads of cultural transmission In the Pamir plateau of the mouth, when the crowd began to consume millet, there is still no evidence of the existence of earlier signs of East-West cultural exchange.Therefore, through the analysis of the cemetery Bronze Age (1500 BC to 600 BC ) Found that the food structure of the ancestors in Xiasakadi cemetery was mainly C_3 animal protein, but there was also a little C_4 class. In individual individuals, the C_4 class even accounted for a large proportion The proportion of archaeological data, the results show that: the ancestors of the main way of life for the pastoral or semi-animal husbandry, but wheat and millet for agriculture is also an integral part of Xia Tomb ground some of the ancestors may have begun to eat millet Crops , Suggesting that oriental cultural factors may occur in the east of the Pamirs, that is, southwestern Xinjiang, as early as about 1500 BC.
