Analysis on the Urban Space Contact of Pan-Pearl River Delta Economic Zone Based on Urban Flow

Based on the theory model of urban flow,the intensity and structure of urban flow in 117 cities of Pan-Pearl River Delta Economic Zone in both 2003 and 2012 are calculated and analyzed,and thereby the space relation of economic circle is analyzed as well. The results showed that more than 75 cities have a smaller intensity of urban flow and a smaller space relation and there exists significant regional differences in the intensity of the urban flow owe to uneven regional development. More than 65 cities have a smaller economy power and a smaller outward service function. The intensity of urban flow still obtains a lager benefit from the secondary industry than from the tertiary industry,the impact of the tertiary industry in urban traffic intensity gradually increased. With time going on,the intensity of urban flow has been affected by both the secondary and tertiary industries from dominated by the secondary industry. The Pan-Pearl River Delta Economic Zone is still in the development stage of industrialization,future structure and evolution of urban spatial linkages could be regulated based on both urban function and spatial distribution of development elements.
