Abstract: The coordination mechanism of transportation network and tourism development of the urban agglomeration in Central Yunnan Province is very complex, and the coordination of the two is the result of the interaction between endogenous and exogenous dynamics. Through the endogenous mutual feedback mechanism—— traffic network evolution of tourism development driving effect, tourism development of traffic network evolution feedback effect realization of Yunnan Urban Agglomeration transportation and tourism development endogenous coupling development. At the same time, and through the external excitation driving mechanism—— natural and environmental constraints attract "mechanism, government policy oriented mechanism, social and economic development gathering, diffusion mechanism in Central Yunnan Urban Agglomerations traffic and tourism development coupling development stimulation. The empirical study shows that the urban agglomeration in Central Yunnan Province has a high degree of interaction strength with the tourism development level, the advantages of traffic and the overall coordination of the tourism development level is better. And put forward the network traffic and tourism development co evolution scheme: the establishment of tourist traffic coordination of tourism spatial pattern, to build a perfect tourist traffic network pattern, improve the coordinated with the traffic network of tourism distributing center system.
