However, the variation of human diets and the inner relationship between human diets and the agricultural transition during this period remain poorly understood. In this paper, the C and N stable isotopes from human and animal bones at the Shenmingpu site （SMPS）, Xichuan County, Henan Province were analyzed. If some outliers （M34, M36, M102） were excluded, the mean δ13C value （（-16.7±0.8）‰, n=15） of humans in Hart Dynasties was dramatically lower than that in the Warring States （（-12.7±0.8）‰, n=14）, indicating that the cultivation of rice and wheat, especially wheat, had been more widely popularized in Han Dynasties. Meanwhile, the range of 615N values of humans （6.6‰-9.3‰） in Hart Dynasties was narrower than that of the Warring States （6.2‰-10.4‰）, suggesting that the animal protein resources in human foods during Han Dynasties were more concentrated. The transition of human diets and the close relationship with the change of agricultural economy in SMPS were due to more stable society, the carryout of new agricultural policies, and the emergence of new agri- cultural tools in Han Dynasties.展开更多
