Abstract:

Based on pollen, paleosol, archaeology materials and terrain features in Gansu-Qinghai Region, this paper reveals that climate was warm and humid at 4 ka BP, culture of Majiayao was distributed over forest-steppe valley region around the Yellow River and its branches. The Liupan Mountain was the eastern boundary of culture of Majiayao, which extended northward to Hexi Corridor and was mainly engaged in planting industry. Around 4 ka BP, environment went worse, and natural zones moved eastward. Meanwhile, culture of Qijia replaced that of Majiayao, and the survival environment shifted to temperate steppe. In order to respond and be adapted to the environmental changes, cultural relics moved southeastward back to low elevation regions, and the proportion of animal husbandry in industrial structure increased obviously.

Key words: Gansu-Qinghai Region, environmental evolution, paleoculture, Holocene
