Analysis of the Space Economic Ties of Urban Agglomeration in the Central Delta Based on City Flow Intensity and GIS

Based on analytical approach to intensity of central functioning and urban mobility, this paper budgets and analyzes the intensity of economic ties and structure in central delta. The research shows that: "multi-center" spatial framework is beginning to take shape in the urban agglomeration of the Central Delta with Wuhan, Changsha and Nanchang as the pole of the spatial framework. Urban agglomeration function remains the dominant function in the development of city group, the lack of city radiation function exists, and the central Delta city group is still in the primary stage of the city group development.
