East-West Cultural Exchanges Between The Eurasian Steppes

Eurasian steppes is located at latitude 50 degrees north of the strip of the Trans-Eurasia steppe zone, to form connections in the topography of natural channel and Western Eurasia. Ancient climate scientists generally agreed that during the millennium and in the BC 2, the entire Eurasian continent's climate began to change, in BC a millennium and presented before the Eurasian steppe dry and cold climate. Settled populations affected by environmental constraints have to be mobile. Comparison of current scholars agree on the Eurasian steppe nomads rise of the economy during this period, while the vertical bands such device is the geographical and environmental change under the various parts in the Eurasian steppe. Vertical bands of special devices, from BC, after two millennium and the Eurasian steppe in the west and, after nearly three years, in the 10th century to the Eurasian steppe grassland around the eastern Heilongjiang River. In the current distribution process, the scattered distribution of present trends spread from west to east.This particular distribution of the Trans-Eurasian steppe decoration, what factors support it spread? What is the factor to maintain such a decoration for thousands of years?The order of materials, discussion of relevant issues, wish to give the Eurasian grasslands of East-West cultural exchange some new clues.
