The remains are identified by phytolith analysis and macrofossil morphological features. Seeds from foxtail millet (Setaria italica), broomcorn millet (Panicum miliaceum), rice (Oryza sativa) and chenopod (possible Chenopodium giganteum) are identified, suggesting that these four crops might have been the staple plant foods in the capital area (Guanzhong area), Shaanxi Province during the Early Western Han Dynasty. Chenopods were often considered as weeds since they have only been rarely found as carbonized seeds in prehistoric sites. This is the first time such a large amount of seeds has been found at a site, which provides strong material evidence for chenopod cultivation with a long history in China. Wheat was thought to be promoted and popularized in the Guanzhong area since the Wu Emporor, Liu, Che (156―87 cal a BC), the fifth emperor of the Western Han Dynasty. No wheat was found at this site, which supports the historical document record that wheat was still secondary in the diet and agrarian economy before the Wu Emperor's reign.展开更多

Focusing on the military defense buildings in the western regions of the Han and Tang Dynasties, CiteSpace software is used to conduct statistical and visual analysis on the hot issues of relevant literature in the military buildings on the silk road. Based on the analysis of frontier hot issues, the research trend of future topics is analyzed and predicted. The research shows that the frontier hot spots of military architecture in the western regions of Han and Tang Dynasties are extensive, and the research trend is steadily rising.展开更多
