Pre-Qin and Han Dynasties are the forming periods of early Chinese states,agricultural stud-ies of these periods are important to learn about the development patterns of early states.However,research efforts about this topic are still lacking.This paper systematically analyzes existing nationwide archaeobotan-ical studies of these periods,evaluating spatial and temporal distributions of available data,and using these data to obtain a preliminary knowledge of Pre-Qin and Han dynasties'agricultural structure developments.Materials collected to date show that research performed so far is rather limited,with most data concentrated in the middle to lower reaches of Yellow river.From the perspective of development phases,most studies are focused on Shang and Zhou periods.Archaeobotanical data analyses show four main crops,including millet,wheat,barley,and rice.The millet-based agriculture had developed beyond northern regions and were also developed extensively in the South.On the other hand,wheat and barley did not become main crops,and their usage patterns are different.In contrast,rice usage is mainly in the South,having complicate interac-tions with other crops.However,due to the limitations of existing data,it is still hard to reconstruct nation-wide agricultural patterns of Pre-Qin and Han dynasties.More archaeological discoveries and integrated re-search efforts are needed to gain full knowledge in agriculture bases of these periods.
