湖北青龙泉遗址东周时期墓葬出土人骨的稳定同位素分析

Stable Isotopic Analysis on Human Bones Excavated from Eastern Zhou Tombs in Qinglongquan Site of Hubei

本文应用稳定同位素分析技术对湖北青龙泉遗址东周时期墓葬出土人骨中的C、N同位素比值进行了测定。结果显示:青龙泉遗址东周时期居民日常饮食习惯中保持着较低比例的动物性食物摄入,植物类食物的摄入中以C3类植物为主,很可能来源于稻谷,还有部分C4类植物的摄入,来源于粟米。本文的研究可以为复原青龙泉遗址东周时期居民的经济模式研究提供有益的线索。

This study examines the stable isotope ratios of carbon and nitrogen in human＇s bone collagen that were excavated from tombs of Eastern Zhou period at the Qinglongquan site of Hubei.The analytic results show that ancient inhabitants at this site took in animal subsistence much less than plant products.The plant products includes two sorts,Sort C3（may come from rice） and Sort C4（may come from millet）,and the former are much more than the latter in frequences.This study offers useful clues for re-constructing the economical pattern of this site.
