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 13C value (( 16.7±0.8)‰, n=15) of humans in Han 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 15N values of humans (6.6‰-9.3‰) in Han 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 agricultural tools in Han Dynasties.展开更多

The non-tectonic deformation phenomena were distinguished at the site of the Shang Dynasty ruins at Daxinzhuang in the Jinan suburbs. In Longshan,sand vein-filled cracks were recognized in the cultural layers of the Chengziya site,Zhangqiu City. Sand veins on the trench wall and sand tubes at the trench bottom were found densely distributed at the Shang and Zhou Dynasty cultural layers,at Qinhuangtai site,Binzhou City. The tectonic and non-tectonic origin cracks were identified on the city wall of the Site of Capital of State Qi,Linzi City. In Rizhao city,parallel distributed sand vein fracture groups were found in the cultural layer of Longshan-Warring States-Han Dynasty at Yaowangcheng site. Typical conjugate shear fractures were identified on the city wall of the ancient city of the State of Xue, Tengzhou City. The above natural deformation phenomena are concentrated in the culture layers of the Spring and AutumnWarring States-Han Dynasties and before, and characterized by seismic sand-soil liquefaction traces,which indicate that these regions might have been in the seismic active episodes in the corresponding periods. The above inference has been confirmed by microscopic data analysis.展开更多
