Analysis and its policy response on the intensity of urban flow in the Lanzhou-Xining-Yinchuan urban corridor

Using the urban flow theory and analytical method of the intensity of urban flow we calculated and analyzed the Lanzhou-Xining-Yinchuan Urban Corridor of the territorial quotient for the main extrovert service,the extrovert energy,the intensity of urban flow and its structure.The results showed: Lanzhou,with high-degree urban flow intensity,is the center of this region;apart from Lanzhou,the overall economic strength is lower than the degree of tendency of urban flow,the overall economic strength and the degree of tendency of urban flow of relative proportions is uncoordinated;The real reason for affecting the urban flow of Lanzhou-Xining-Yinchuan Urban Corridor development is the collectivity strength shortage in the cities.The direction of intensifying urban flows of these six cities is that Lanzhou should improve the integrated service ability,Xining and Yinchuan should perfect the urban function,the other cities should adjust the industry structure,enhance the urban economic,and present the corresponding optimal strategies of enhanced urban flow for each city.
