摘要 与传统的农作物不同,杂草在考古学研究中常被学者忽视。本文通过对榆林地区新石器时代晚期植物、动物和碳、氮稳定同位素数据的再分析,发现以藜科和豆科为代表的杂草与人类和家畜的关系非常密切。基于植物志的记载,并结合周边区域现生杂草的碳、氮稳定同位素数据,初步确定藜科并非是单纯的C3类杂草,其主要属种是与人类和家猪密切相关的C4类食物,而豆科应是绵羊、山羊和黄牛的主要饲料。碳、氮稳定同位素研究可能需要更多的理论思考。 Compared to the traditional crops,weed grasses are often overlooked by scholars in archaeological studies.This research conducted an analysis of floral and faunal remains and stable carbon and nitrogen isotope data from late Neolithic sites in the Yulin region and found a close relationship between the weed grasses,represented by Chenopodiaceae and legumes,and humans and domestic livestock.Based on floral records and stable caron and nitrogen isotope data of modern weed grasses from the nearby regions,we can confirm that the Chenopodiaceae remains found at the archaeological sites were not just C3-based weed grasses.Rather,most of them belonged to C4-based plants that were closely associated the diet of both humans and domestic pigs.Similarly,the legume species might be consumed as fodder of sheep,goat and cattle.Our research calls for more theoretic rethinking on the archaeological studies of stable carbon and nitrogen isotope.
