The carbonized remains of a wide range of plats,including five crops,namely foxtail millet,broomcorn millet,rice,wheat and soybean,have been collected through flotation at Yanshi Shang City.The millet occupies an important position.The proportion of rice is prominent.The percentage of broomcorn millet and ubiquity are lower than those of rice.The site contains a lower level of wheat and soybean than contemporaneous sites.The structural characteristics of the proportions of the crops are considerably close to those of Erlitou Site of Erlitou period,and differ from those of Erlitou Site and other nearby sites of Erligang period and of Zhangdeng Site of pre-Shang period,reflecting the influence of natural environment,political factors and dietary traditions on the composition of crops planted by large settlements.In areas around Mount Song,rice was gathered near large settlement,indicating that it might have certain"political"significance.Compared with sites of Erlitou period,sites dating back to Erligang period see significantly higher proportions of wheat and more wheat unearthed.However,the proportions of wheat among large capitals are different,and the reasons behind these differences need to be further studied and analyzed.
