A Preliminary Analysis to the Diet of the Primitive Residents of the Xichengyi Site in Zhangye,Gansu

前言西城驿遗址位于河西走廊上的甘肃省张掖市,年代属于青铜时代。20102011年对该遗址进行了考古发掘,发现房址、墓葬、灰坑等遗迹,出土各类陶器、石器,以及动植物遗存、冶炼遗存等,为河西走廊及相关地区青铜时代的考古学文化以及人类生活环境、生活状况等方面的研究提供了重要资料[1]。本文根据对出土人骨和部分动物骨骼的分析。

Xichengyi Site located in Hexi Corridor belongs to Siba-Machang Culture. In addition of charred grains of wheat and millet, bones of human beings and domesticated animal bones were also discovered in this site. Based on the analyses of 813C and 815N of these human and animal bones, this paper explored the paleo- diet pattern and intended to provide a basis for the research of the subsistence mode and the way domesticated animals were raised. The results showed that, although charred grains of wheat were found in almost every layer, the ratio of C4 plant, which should be foxtail millet or proso millet, was still high in people＇ s diet. And it was also shown that the value of δ15N was higher in the human bones in the lower strata than that of the human bones in the higher strata. It means that there is a difference in meat-consuming between them.
