Study On The Spatial Evolution Of The Ancient Tea Horse Road And Multi-ethnic Cultural Exchanges In Yunnan

Since ancient times,the ancient tea-horse road has been an important trade channel for the communication of many ethnic groups such as Na,Tibet,Bai and Han in southwestern China.It has played a huge role in the economic and cultural exchanges along the way.With the continuous development of the “One Belt,One Road” strategy Advance,the new era has given the new positioning of the tea-horse road.Therefore,the analysis of the relationship between the ancient tea-horse road and the multi-ethnic cultural exchange space is of great significance for strengthening the economic and cultural development of multi-ethnic regions,the integration of ethnic relations,national unity and the maintenance of border security.Based on historical data and field investigation,this paper discusses the temporal and spatial coupling relationship between the ancient tea-horse road and the national cultural exchange from the perspective of history geography,and attempts to analyze the driving mechanism behind this high superposition.The results show that:(1)Tea Horse The evolution of the ancient road shows a clear life cycle law in time.The Tang and Song Dynasties were in the embryonic period,and the Ming and Qing Dynasties were in the period of prosperity.After the founding of the People’s Republic of China,the Tea Horse Road entered a period of decline.(2)The ancient tea-horse road in the sacred space shows the development mode of “point-line-net” in space.First,a hub-type trade node city is formed,and then the sub-regional trade towns are developed based on these node towns.The point-and-line lines are connected to form a network,and finally a transportation network system covering the entire border area is formed.(3)The spatial and temporal evolution of the ancient tea-horse roads in Tibet has a high degree of overlap with the spatial evolution of ethnic cultural exchanges.The prosperity of the tea-horse trade has accelerated the cultural exchanges between the various ethnic groups.The expansion of the ancient tea-horse route has also expanded the space for ethnic cultural exchanges.On the contrary,the expansion of the national cultural exchange space also promotes the expansion of the ancient tea-horse road,and the two present a mutually overlapping spatial relationship.(4)The driving factors of the evolution of the ancient tea-horse roads along the line and the ethnic cultural exchanges along the line are similar.They are based on the differences in natural geographical environment and the complementarity of production and lifestyle.The central government,local forces and foreign forces have three shares.The result of the mutual play and interaction of forces.
