Agropastoralism has prevailed in Inner Asia since the Bronze Age. It is an optimal subsistence strategy of inhabitants for adaptation to arid marginal environment. However, previous studies paid little attention to different development trajectories of this mixed economy within similar habitat. The Turpan and Hami Basins, located in eastern Tianshan Mountains of Xinjiang, are two typical desert oases with extremely dry climate, providing us with an appropriate region to investigate the issue. In present study, radiocarbon dates (n = 154) of eight typical sites in these two basins were reviewed and used to reconstruct the prehistoric chronology sequence prior to Han Dynasty (2200 cal BP). Then the data of botanical and faunal remains and stable isotope analyses (n = 159) of human diets from these sites were also reviewed for reliably revealing the subsistence economy pattern. Combining the time scale with multiple biological proxies, results show that, from the Bronze Age to early Iron Age, inhabitant subsistence in the Turpan Basin was dominated by livestock herding and supplemented by low-investment cereal crop cultivation, while the agriculture in Turpan Basin has developed significantly by the later period of Subeixi Culture. In contrast, agriculture-based economy was continuously developed in the Hami oases. Although the climate is very dry in both basins, temperature in warm seasons is much higher in the Turpan Basin. Besides thermal condition, size, range and convenient availability of highland pasture located at the southern flank of the Tianshan Mountains, are main driving factors leading to differentiated development trajectories of agropastoralism. Apart from that, cultural factors like economy, culture and technology communication along with population migration also impact local subsistence economy pattern. [ABSTRACT FROM AUTHOR]
