中文摘要：

探讨塔山先民食物结构和生计方式，有助于全面揭示塔山遗址及其所在的长江下游地区新石器时期先民的稻作农业发展、动植物资源利用情况和史前文化面貌等考古学信息。塔山遗址动物和先民骨骼胶原蛋白C、N稳定同位素分析表明，野生动物属于陆生系统C3草食性食物结构。家猪的食物来源中C3植物类食物占主体，兼有一些δ^15N值较高的食物，可能与人的饲喂活动有关。人主要依赖于C3类食物，这可能来自水稻等C3类食物的贡献结合考古学资料，对比动物和先民稳定同位素结果，发现塔山先民主要依赖稻作农业经济，可能辅以少量采集经济毗邻大海的塔山先民摄取的动物蛋白资源并不是来自海生系统，而主要来自基于陆生系统的渔猎经济，少量来自家畜饲养、

英文摘要：

We could reveal prehistory culture characters, rice agrienltura｜ economy de,elopment, plant and meat resources based on the study of the diet, subsistence strategies analysis of the Tashan site and comparison between the Tashan site and the other Neolithic age archaeological sites. Stable isotopic carbon, nitrogen analysis of animal and human bone collagen from the Tashan site indicated that, wild animals hare a C3 -based terrstrial diet. Domestication pigs hare a diet of prednrninated C3 -based foods and some high δ^15N values foods, which could obtain from the human feeding. Combined with the archaeological records and the isotopic analysis results, we found that the subsistence strategies of the Tashanhumans mainly relied on the riee agricultural economy during the late period. The humans obtained lots of animal meat proteins, which probably mainly from the wild animals, and few tYom the domesticated animals. The humans had a small reliance on the marine foods.
