Analysis of the Forming Mechanism of Urban Tourism Core-Periphery Spatial Structure in the Yangtze River Delta

It has formed multi-layer and multi-central features to the urban tourism core - periphery spatial structure in the Yangtze River Delta. The general evolution trends presented by this kind of tourism structure can be thought that Shanghai city is the huge tourist city in the Yangtze River Delta,and is the central city in view of the second layer among the layers of urban tourism core-periphery spatial structure; the cities such as Nanjing,Wuxi,Suzhou,Hang-zhou and Ningbo are increasingly becoming very important tourist cities in the Yangtze River Delta; the cities such as Taizhou,Zhoushan,Shaoxing,Nantong,Yangzhou are fringed continuously. This paper indicated that the forming of urban tourism transportation hinges were the main forming mechanism of urban circle-layer core-periphery tourism spatial structure in the Yangtze River Delta,and spatial mutual benefits of urban tourism resources were the resource fundamental during the forming of this kind of structure.
