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

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

The two graves are large in size, rectangular in plan, with ramping tomb-passages and, on each wall, 14 steps. Either of them contains a double outer and a double inner coffins, the former being partitioned into five cabinets. The funeral objects are very rich, numbering 617 pieces/sets for Tomb No.1 and 587 pieces/sets for Tomb No.2, and more than 1,000 bamboo slips were unearthed from the second grave. Two horse-and-chariot burial pits were discovered on the western side of the tombs. Their contents consist of 33 chariots and 72 horses in Pit 1 and 7 and 16 respectively in Pit 2. The discovery will greatly push forward the study of the Chu culture.展开更多

In 1990, excavation was carried out in its northeast, where four large-sized tombs were found to be of the Warring States period. One of them Tomb No.2 is shaped like the character “甲” in plan, with the tomb-passage pointing to the south. The tomb pit consists of a surfaceand an underground parts; and the coffin chamber is located somewhat to the south of the center of the pit, and contains an outer and double inner coffins. At the back of the chamber is a rectangular sacrificial pit with 12 human victims. More that 20 single-shaft chariots were yielded from the tomb pit, behindwhich is a large horse burial pit. Among the rich funeral objects, the pottery comprises the ding tripod,gui food container, pot, dou stemmed vessel and its cover, dul round vessel, li tripod, lei pot, zhousaucer, pan basin, yi ewer, jian basin, jin table-shaped stand, ladle, spade and tomb figurine; thebronzes include the chime-bells, ge dagger axe, spear, shu battle mallet, halberd, sword and arrowhead;and the stone implements are represented by the chime stone. The tomb shape and the features of thegrave goods show that the burial goes back to the early Warring States period, and the tomb-owner must have been an influencial figure in the rank of high minister and noble (卿大夫).展开更多

This is a character with associative compounds. It is made up of “lu卤” and “min 皿”, meaning making salt by boiling salty water. The exact identification of this character will much contribute to the understanding of the characters for “salt” in other writings of ancient China. The seal “ Xi (Xi) Yan Zhi Xi (徙)盐之玺”, i.e. “Seal of Salt Circulation”, was an official seal used in the course of salt circulation for the purpose to ensure regular salt trade and effective taxation and to avoid the repetition of tax levy.展开更多

文摘Historical records and archaeological remains indicate that the Chinese agricultural economy changed significantly from the Warring States (475-221 BC) to Han Dynasties (206 BC-220 AD), i.e., from rice-millet based agriculture to rice-millet-wheat based agriculture. 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.

文摘In September-December 2002, the Hubei Provincial Institute of Cultural Relics and Archaeology excavated the Nos. 1 and 2 Chu State tombs and the horse-and-chariot burial pits auxiliary to them in the Jiuliandun cemetery of Wudian Town in Zaoyang City, Hubei Province. The two graves are large in size, rectangular in plan, with ramping tomb-passages and, on each wall, 14 steps. Either of them contains a double outer and a double inner coffins, the former being partitioned into five cabinets. The funeral objects are very rich, numbering 617 pieces/sets for Tomb No.1 and 587 pieces/sets for Tomb No.2, and more than 1,000 bamboo slips were unearthed from the second grave. Two horse-and-chariot burial pits were discovered on the western side of the tombs. Their contents consist of 33 chariots and 72 horses in Pit 1 and 7 and 16 respectively in Pit 2. The discovery will greatly push forward the study of the Chu culture.

This is a character with associative compounds. It is made up of “lu卤” and “min 皿”, meaning making salt by boiling salty water. The exact identification of this character will much contribute to the understanding of the characters for “salt” in other writings of ancient China.
