Spatial Structure with Base of Tourist Flow Scene in Yangtze-delta

With the rapid development of tourism industry,residences increasingly improved their requirements of tour convenience.As a part of tourism,the research of tourist flow had gone deeply.Taking 2004 year's data of 15 cities in Yangtze-delta as an example,this paper built the city tourist flow intensified model with the classical gravitation model.After probing into the spatial structure of tourist flow in inner Yangtze-delta,the article came to the conclusion: First,after calculate the index of destination,the index of orientation and the index of tourist flow in inner Yangtze-delta,we found that destination and orientation system are shown as a circle structure with Shanghai as the center;in other word,the level of destination and orientation will be lower as it is far away from the Shanghai city.Second,Shanghai has strong interaction with other cities in Yangtze-delta except Zhoushan city, and Shanghai has more central than other cities;the peripheral part of Yangtze-delta showed marginality.Third,provided α=1,we calculate that β=1.533 3,γ=0.589 7;this result show that the inner Yangtze delta tourist flow develops well with more posibilities to improve.Fourth,we should strengthen net construction in surrounding area,especially in the one circle, two belts,which includes Nanjing tourism circle,the north bank belt of Yangtze River and the Hangzhou-ningbo tourist belt,in order to realize rational adjustments and structural optimization for spatial direction of tourist flow.When we strengthen net construction,we can enhance the tourism network of Yangtze-delta,and accelerate the development of tourism.If some governments want to formulate suitable tourism development strategy,this article could offer some references.
