Based on the “lake effect” hypothesis and urban spatial structure theory, a theoretical model of the lakes which influence the economy surrounding the urban is put forward in the paper, and the area surrounding Poyang Lake as a case is empirically analyzed. The result indicates that under the influence of Poyang Lake, the city distribution density and traffic network density in the area show a trend of first slowly increasing then gradually decreasing corresponding to the distance from lake, while they show a increasing trend when the distance further increases. Therefore, the area surrounding Poyang Lake was divided into three urban economic regions according to the extreme principle and special attributes. The empirical analysis clearly shows that the model not only can theoretically explain how the lakes affect the space differentiation of the urban economic regions, but also can provide a quantitative model that can be extended.
