摘要
霞浦屏风山贝丘遗址出土了1件未知属性猪骨样本,拟通过骨样的C、N稳定同位素分析,揭示此猪个体生前的食物结构特征,通过与已发表有关数据进行对比来推断该猪的属性。为此,对该骨样进行了骨胶原提取和碳氮稳定同位素比值测定。测得该猪骨样本骨胶原的δ^(13)C值为-12.2‰,δ^(15)N值为4.9‰。碳同位素比值显示该猪的食物结构中既包含C_3类植物,也包含C_4类植物,但更偏向于C_4类植物。而氮同位素比值则表明此猪个体营养级较低,摄入肉食较少,但仍高于对照组野猪及部分陆地野生哺乳动物的营养级。综合分析,研究认为该猪的食物结构在一定程度上依赖于人类的供应,应该是驯养的家猪。同时,该猪食物结构中的碳四植物来源提示该遗址可能存在粟作农业。
In this study,carbon and nitrogen stable isotope analysis was used on collagen extracted from an unclearly classified pig bone sample from the Pingfengshan shell midden site in Xiapu County.The δ^（13）C value of this sample was determined as -12.2‰,and the δ^（15）N value 4.9‰.The value of carbon isotope ratio indicates that the food consumed by the pig contained both C3 and C4 plants,but mainly C4 plants.The nitrogen isotope ratio shows that the pig was less carnivorous and of a lower trophic level.However,the value of δ^（15）N is still higher than the contrast group of wild boars and wild terrestrial mammals.Based on comprehensive study,it is argued that the feeding of the pig depended on human supply to some extent,thus the pig was likely to have been cultivated.Meanwhile,the C4 plant sources in the pig＇s food structure suggest that millet farming may have existed at the site.
