摘　　要：国家"十二五"规划中,长江中游地区被列入我国城市化21个主要地区之一,促进长江中游城市群的发展,将使其成为承东启西、连南通北的平台。以长江中游城市群为研究区域,采用引力模型和城市流强度模型,对长江中游城市群内部城市的经济联系进行了量化测度。结果表明,长江中游城市群的经济联系呈现明显的层级关系,武汉是城市群的发展核心,长株潭、南昌则为城市群的次级中心;组成长江中游城市群的次级城市群内部空间联系具有差异性,武汉城市群和长株潭城市群内部城市经济联系紧密,并且两个城市群之间经济联系强度较高,环鄱阳湖城市群内部联系松散且相对边缘化;长江中游城市群需要发展中级城市以增强外向功能性。In recent years, the middle reaches of the Yangtze River has become one of the most important agglomerations in China. The paper takes the economic zone of the middle reaches of the Yangtze River as the study area, choosing the 2010 as the time section. The study applies the gravity model and the degree of urban flow as the model to measure the cities of the economic zone of the middle reaches of the Yangtze River. The results show as follows： the economic links of the middle reaches of the Yangtze River show obvious hierarchy. It could be divided into four levels in terms of the spatial economic connection through the gravity model： Wuhan city has been firstly ranked. Changsha-Zhuzhou-Xiangtan city and Nanchang city have been secondly ranked. The composition of the middle reaches of the Yangtze River is different from each other in internal space contact. Wuhan metropolitan and Changsha-Zhuzhou-Xiangtan urban agglomeration are closely linked urban space in cities, and it shows that the economic relation between Wuhan metropolitan area and Changsha-Zhuzhou-Xiangtan urban agglomeration happens frequently and closely under the current situation. At the same time, Yinchang-Jingmen-Jingzhou urban agglomeration is less related than Wuhan metropolitan and Changsha-Zhuzhou-Xiangtan urban agglomeration. By contrast, cities in urban agglomeration around the Poyang Lake has loose spatial economic association and the urban agglomeration has been marginalized, so that Poyang lake urban agglomeration＇s status in the Mid-Yangtze river has yet to be improved and urgently integrated. In order to increase the outward function, the middle reaches of the Yangtze River should develop the secondary cities.
