摘要:

基于“湖泊效应”假设与城市空间结构理论,提出了湖泊影响周围城市经济的理论模型,并以环鄱阳湖区为例进行实证分析。研究显示,在鄱阳湖影响下,环鄱阳湖区城市分布密度和交通网络密度都随距湖距离变化而呈现出先逐渐增大继而逐渐减小的趋势,但随距离进一步增加,城市分布密度和交通网络密度又呈增大趋势,由此根据极值原理和专题属性将环鄱阳湖区划分为3个城市经济影响区。可见,该模型不仅可以从理论上解释湖泊如何影响周围城市经济区空间分异,而且可以提供一个定量分析模型加以推广。

Abstract:

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.

Key words: Lake Effect, urban economic region, buffer analysis, lake effect model, the area surrounding Poyang Lake
