The formation of the grassland Silk Road is closely related to the natural ecological environment.

The formation of the grassland Silk Road is closely related to the natural ecological environment. In the geographical context of the whole Eurasian continent, communication between East and West is extremely difficult. Environmental archaeological data show that Eurasia was only conducive to human east-west transportation in the mid-latitudes between 40 and 50 degrees north latitude, and this region was the site of the steppe Silk Road. This is the core area where nomadic culture and farming culture intersect, and it is an important link point of the grassland Silk Road.
For the grassland Silk Road, the demand for Commodity Exchange originated from the division of labor between agriculture and animal husbandry in primitive society. The dryland agricultural areas in Central Plains were mainly agricultural, rich in grain, hemp, silk and handmade products, while the development of agriculture required a large amount of animal power (cattle, horses, etc.). Northern grassland area is mainly based on animal husbandry, rich in cattle, horses, sheep and skin, hair, meat, milk and other animal products, and lack of food, textiles, handmade products. This economic relationship between the Central Plains region and the grassland region, with mutual demands and interdependence, is the basic condition for the formation of the grassland Silk Road [50]. Therefore, the grassland Silk Road is also called "fur road" and "Tea Road" because of its characteristics.
