【摘要】：霞浦屏風(fēng)山貝丘遺址出土了1件未知屬性豬骨樣本,擬通過(guò)骨樣的C、N穩(wěn)定同位素分析,揭示此豬個(gè)體生前的食物結(jié)構(gòu)特征,通過(guò)與已發(fā)表有關(guān)數(shù)據(jù)進(jìn)行對(duì)比來(lái)推斷該豬的屬性。為此,對(duì)該骨樣進(jìn)行了骨膠原提取和碳氮穩(wěn)定同位素比值測(cè)定。測(cè)得該豬骨樣本骨膠原的δ~(13)C值為-12.2‰,δ~(15)N值為4.9‰。碳同位素比值顯示該豬的食物結(jié)構(gòu)中既包含C_3類植物,也包含C_4類植物,但更偏向于C_4類植物。而氮同位素比值則表明此豬個(gè)體營(yíng)養(yǎng)級(jí)較低,攝入肉食較少,但仍高于對(duì)照組野豬及部分陸地野生哺乳動(dòng)物的營(yíng)養(yǎng)級(jí)。綜合分析,研究認(rèn)為該豬的食物結(jié)構(gòu)在一定程度上依賴于人類的供應(yīng),應(yīng)該是馴養(yǎng)的家豬。同時(shí),該豬食物結(jié)構(gòu)中的碳四植物來(lái)源提示該遺址可能存在粟作農(nóng)業(yè)。
[Abstract]:A pig bone sample with unknown properties was unearthed in Beqiu site of Pingfeng Mountain, Xiapu. The food structure of the pig was revealed by Con N stable isotope analysis. The properties of the pig were inferred by comparing it with published data. The extraction of bone collagen and the determination of the ratio of carbon and nitrogen stable isotopes were carried out, and the 未 ~ (13) ~ (13) C value of bone collagen of the pig bone sample was measured to be -12.2 鈥，
