摘要:

科学合理地划分城市经济联系是完善城市圈功能布局、实现经济一体化发展的基础。通过引入相对引力常量、改进城市引力模型,并以武汉城市圈为例,探讨城市经济联系空间结构及引力格局划分方法。结果如下:①改进的引力模型能客观反映城市间不相等的相对引力现状;②武汉城市圈呈现出经济辐射型、经济依赖型、经济复合型3类城市经济联系结构,武汉市是城市圈内唯一的强经济辐射型城市;③根据城市经济联系结构,将武汉城市圈引力格局划分为以孝感—武汉—咸宁为中心,黄石—鄂州—黄冈和仙桃—天门—潜江为两翼的城市组团。

关键词: 城市引力模型, 相对引力常量, 引力格局划分, 武汉城市圈

Abstract:

Scientific zoning of urban economic linkage structure is essential for improving and optimizing the functional layout of metropolitan areas, as well as for guiding integrated economic development. Based on the relative gravity vector introduced in this article, the conventional gravity model had been improved and applied in the Wuhan Metropolitan Area for exploring the economic linkage structure and gravity zoning. The results show that: the improved gravity model can indicate the actual conditions of unsymmetrical relative gravity between two cities. It shows three types of economic linkage structure, including driving, dependent, and complex structures in the Wuhan Metropolitan Area, and Wuhan was the single city that showed strong driving economic power in relation to other cities in the area. According to the gravitational attraction that represents economic linkage structure, cities in the area were divided into three zones, namely the "Xiaogan-Wuhan-Xianning", "Huangshi-Ezhou-Huanggang", and "Xiantao-Tianmen-Qianjiang"urban cooperation groups, with the former as the "center" and two latter groups form the "wings".

Key words: urban gravity model, relative gravity vector, gravity zoning, Wuhan Metropolitan Area
