Abstract:

Yangshao culture is the representative of the Holocene Neolithic culture in the north of China. The Neolithic culture in Yellow River Basin expanded quickly in the Yangshao period, from the previous Weihe River valley in the west to eastern Qinghai, east to the lower reaches of Yellow River, north to Chifeng of Inner Mongolia, and south to most parts of Hanshui River valley. The warm and wet Holocene megathermal climate conditions were closely related to the quick expansion of the Yangshao culture. In the Yangshao period, as the powerful monsoon increased rainfall, the 400 mm isohyet moved towards northwest about 200 km. This means that the northern monsoon boundary system has expanded to the northwest inland, resulting in the expansion of the cultivation of the millet, and the Yangshao culture, which is characterized by millet cultivation, has also expanded accordingly. The 400 mm isohyet became the west boundary of Yangshao culture expansion, as well as the boundary of Yangshao millet planting area and north microliths hunting-gathering area in the Holocene megathermal. The summer monsoon in northern China in the mid-Holocene period increased. The expansion of the monsoon to the interior led to the expansion of Yangshao culture in northern China. The expanded Yangshao culture also laid the early form of the relatively unified Chinese civilization, and eventually became one of the important sources of Chinese civilization.

Key words: Yangshao culture, expansion, 400 mm isohyet, mid-Holocene
