摘　　要：利用C和N稳定同位素分析方法研究了青海宗日遗址先民的食谱,探讨了先民的经济模式以及食谱变化趋势。所有人骨骨胶原中的C,N含量以及C/N摩尔比,均表明样品保存较好,可用作食谱分析。骨胶原的1δ3C值和1δ5N值分析显示,先民主要以C4类植物为食,也摄取一定量的肉食,反映了以粟、黍等为主食而渔猎为辅的生活方式。性质未明墓葬与宗日墓葬之间存在的较大食谱差异,可能与其来自不同文化密切相关。宗日遗址在发展过程中,先民食谱中C4植物增加而肉食类减少,反映了农业加狩猎采集的混和经济模式向稳定农业模式转变的趋势。The Zongri Site is located on the north side of the Huanghe River, between two villages Kaligang and Banduo of the Bagou Township, Tongde County, Qinghai Province. Zongri Site was firstly considered as the western most site of the Majiayao Culture. However, with the excavation going on, more and more evidence showed that it might represent a new kind of archaeological remain. Numerous potteries were found with a particular style （Zongri Style） which was completely different from that of the Majiayao, and the unique pronely extended burial of the body which is common in these tombs is rare in both Majiayao and other contemporary cultures. Sites with similar characteristics have been discovered along the the Huanghe River and its branches in the Gonghe Basin. They therefore, together with the Zongri Site were proposed to be a relatively independent culture called the Zongri Culture which is dated to 5200 - 4100aB. P. according to the tree-ring correction of ^14C dating and periedization by potteries. In the area of the Zongri Site, there are altogether 341 tombs being discovered. Among them 175 have been definitely identified as belonging to the Zongri Culture, while others with their age tentatively undetermined. Those Zongri Culture tombs can be classified into three periods due to the assemblage of the buried potteries. 24 human bone samples were collected from both determined tombs （ 18 ） and undetermined tombs （5, among which M32 is a joint burial tomb, with 2 samples collected）. The human diet from the Zongri Site was investigated by stable isotopic analysis on these bones. In general, all samples are well-preserved. Their C/N （tool ratio） ranges from 3. 16 to 3. 23 which is within the standard （2. 9 - 3. 6）, they are thus believed to be uncontaminated and can be used as palaeedietary indicators. Stable isotopic analysis on these samples （δ^13C ： - 12. 20‰ ～ - 8.49‰ and δ^15N ： 7. 59‰～ 9. 23‰） shows that C4 plants （mainly millet） was the main food and animal
