青海官亭盆地植物考古调查收获及相关问题

The Result and its Related Issues of the Investigation of Archaeo-botanical Remains in the Guanting Basin,Qinghai

目前对于甘青地区青铜时代的经济状况存在不同认识。青海官亭盆地的植物考古调查结果显示,青铜时代的齐家文化和辛店文化农业皆是以粟、黍为主的旱作农业;辛店文化时期新出现了大麦和小麦等麦类作物,且以大麦为主;辛店文化时期黍的相对增加可能与气候变干有关。本次植物考古研究的结果不支持甘青地区青铜时代经济形态是从农业向畜牧业转型的观点。

There are different opinions about the economic formation in Gansu and Qinghai regions during the Bronze Age. According to the archaeobotanical investigation of the Guanting Basin, Qinghai province, the agriculture of the Qijia and Xindian culture belonged to dry-farming that is based majorly on foxtail millet （Setaria） and broomcom millet （Pare＇cure miliaceum ）. It was during the Xindian period that wheat and barley appeared in this region, and among them barley was the most dominant species. The rise of broomcorn millet during the Xindian period may be related to the change toward dry climate. Archaeobotanical findings do not support the view that the economy formation in Gansu-Qinghai region was shifting from agriculturebased to husbandry-based during the Bronze Age.
