The agricultural activity strengthened in Xishanping from 5100 cal a BP. It appeared the earliest cultivation of prehistoric rice in the most northwest China at 5070 cal a BP. The sudden disappearance of conifers and expansion of chestnut trees is likely to be the result of selective hewing of conifers and cultivation of chestnuts at about 4600 cal a BP. There existed 8 crop types of foxtail millet, broomcorn millet, rice, wheat, barley, oats, soybean and buckwheat at Xishanping between 4650 and 4300 cal a BP, which cover the main crop types of the two origin centers of East and West Asia. Not only has the wheat and barley been approved to spread to northwestern China, but the earliest complexity agriculture in Neo-lithic China appeared in Tianshui, Gansu Province.展开更多

It continued from 5070 to 4300 cal. a BP. This is so far the oldest and the most northwestern record of cultivated rice in Neolithic China, which extends the known region of prehistoric rice cultivation at least 2° longitude to the west. This finding provides important evidence for reconstructing the cultivation region of rice at 5000 a BP (an important time period), and its spreading history in East Asia, during the Neolithic.展开更多

Containing evidence of the superimposion of the successive layers from the Dadiwan I culture to the Qijia culture, the two sites revealed a complete evolutionary sequence of the prehistoric culture in the Weihe River valley. The book constitutes a batch of important achievements in the prehistoric archaeology of Gansu, and has great scientific value and academic significance to studying the history of primitive society in the Northwest of China.展开更多
