Stable Isotope Analysis On Human Skeletons From The Warring States Period Of Dashengzhao Cemetery In Changge

In the past,the study of human diet was mainly based on literature as well as different forms of intuitive archaeological materials,such as plant remains and animal bone remains,but the scientific and technological archaeological methods based on the intuitive archaeological relics such as animals and plants can extract deeper information and provide a new perspective for the study of ancient recipes.At present,the most commonly used method in the study of human diets is the analysis of stable isotope.Through the analysis of ossein?commonly used as stable carbon and nitrogen isotopes?in human bones,to probe the dietary situation of an individual in the last few decades.In this paper,the values of?¹³C and?¹⁵N in the bone ossein of human bones in the Warring States Period of Xuchang,Henan Province were tested and analyzed.On the one hand,we can judge the recipe structure and meat level of human from Dashengzhao in the Warring States Period.On the other hand,it can provide new information for the study of the specific status of millet and wheat in the main grain of the northern part of China during the Eastern Zhou Period,and provide new materials for the study of the regional features of the agricultural history and the human diet in Eastern Zhou Dynasty.The stable carbon and nitrogen isotopic analysis of the ancestors in the Warring States Period showed that the food structure of the ancestors in the Warring States Period was characterized by a mixture of C3 plants?wheat?and C4 plants?millet?.The overall carnivorous level is limited,and there are some differences in the internal carnivorous level.During the Warring States Period,there were various differences in burial?filling earth,second floor platform,head portrait,funeral objects,etc.?indicating that there were differences in internal funeral customs or cultural traditions,and even in the economic status of Dashengzhao cemetery during the Warring States Period.However,these differences did not affect the recipe structure of the ancestors,that is,the dietary characteristics of the ancestors were not significantly affected by the different cultural backgrounds.Of which The individuals without burial ware obviously ate more wheat,which further confirmed that wheat was mainly consumed by the lower economic groups at this time.In addition,excluding M54,the?¹³C values of the rest of the immolated individuals were obviously lower,indicating that the rest of the immolated individuals were mainly C3 plants?wheat?,which suggested that the economic strength or living condition of the rest of the immolated individuals might be lower or worse than that of the straight ones.The horizontal and longitudinal comparison in the Warring States Period showed that wheat began to be consumed by northern residents in the Eastern Zhou Dynasty in the Central Plains and became one of the main grains at that time.The stable carbon and nitrogen isotope analysis of the Han Dynasty and the ancestors after the Han Dynasty in the Dashengzhao cemetery shows that the Han Dynasty After the Han Dynasty,the consumption of C3 plants increased,that is,the consumption of wheat increased,and the meat resources were not much different from the Warring States Period.It is assumed that the proportion of wheat in the main grain of the people in the Han Dynasty and after the Han Dynasty increased gradually and the position of wheat gradually increased in the Dashengzhao cemetery at that time.
