Plant Macrofossil Analysis Of Xueshan Site In Chengjiang County Of Yunnan Province

Xueshan site that is a part of the Shizhaishan culture (Dian culture) is located in Chengjiang County of Yunnan Province. In this paper, we will analyze23typical flotation samples systematically. These samples were collected by the Cultural Relics and Archaeology Institute of Yunnan Province in2011. We found more than15300carbonized seeds from these samples, which including7kinds of crops and30kinds of weeds. There is also a small amount of fruit remains. The identification showed wheat seeds were most common, followed by rice seeds. Foxtail millet, buckwheat, broomcorn millet, and soybean seeds are also important crops for Xueshan’s inhabitant.Wheat is the most important crop in Xueshan site. However, the size of these wheat varies greatly. In order to analyze the influence on carbonized wheat which caused by carbonization environment, we attempt to conduct carbonization experiment on modern seeds. At the same time, We combine traditional archaeological data such as tools and images with wheat stalks from flotation to investigate wheat harvesting and processing methods in Bronze Age of Dianchi District.Finally, this paper further probes into the formation and evolution of agricultural structure with documents and flotation results during the Bronze Age of Yunnan. we also think that the political factor played an important role in this evolution.
