新砦遗址出土部分动物骨的碳氮稳定同位素分析

新砦遗址地处中原,年代为龙山文化晚期与二里头文化一期之间。通过应用碳氮稳定同位素分析方法对于新砦遗址2002年发掘期间出土动物骨的分析显示,家畜的食物均是以C4类植物为主,而结合遗址出土植物遗存的研究结果,C4类植物应为粟黍。其食物之间的差异表明,该遗址不同种类家畜之间的饲养方式有所不同。

Xinzhai Site is located in the Central Plains, and its date belongs to the period between the late Longshan Culture and the first phase of Erlitou Culture. Based on the stable isotope analysis of δ13C and δ15N, the animal bones excavated in Xinzhai site in 2002 were researched. The result is shown that C4 plant is the staple food for these domestic animals and the C4 plant should be millet referring to the crops found in the site. The diversity of δ3C among different kinds of animals means that the way of raising is different for different kinds of animals in the site.
