摘要:

江淮城市群是安徽省结合省域经济发展和中部崛起战略的实际而提出的省域经济发展新思路,发展势头良好。本文依据地理学相关理论,运用城市流和城市空间相互作用强度模型,定量测度了江淮城市群中各城市的城市流强度和11个城市之间的相互作用强度,揭示出江淮城市群空间联系方向,并提出江淮城市群空间整合的发展模式。结果表明:合肥、芜湖在城市群中发挥着较为重要的作用,是城市群中最为重要的两个节点,江淮城市群是一个"弱核型"城市群;城市群的空间联系方向是以合肥为中心,呈圈层状向外辐射以及沿交通走廊呈轴线状拓展,空间联系交通指向明显。通过实行"圈层"、"T"型及"双核"型空间整合模式,可以实现江淮城市群的协调发展。

Abstract:

Urban agglomeration is an advanced spatial organization form of urbanization and plays an important role in regional socio-economic development. Jianghuai urban agglomeration is a new idea proposed by Anhui Province for regional economic development combination of provincial economic development and central China rising. Based on geography theory and the new cask theory and by using city flow and intensity of urban spatial interaction models, the study calculates quantitatively city flow intensity of Jianghuai urban agglomeration and spatial reciprocity intensity between the cities. The study reveals the spatial development direction of Jianghuai urban agglomeration, and puts forward the spatial integrated patterns of Jianghuai urban agglomeration development. The results show: (1) The total value and the average value of city flow intensity of Jianghuai urban agglomeration are lower than those of the other urban agglomerations. As the core of urban agglomeration, the advantages of Hefei city are not obvious in comparison with Wuhu and Ma'anshan cities. Therefore Jianghuai urban agglomeration is a "weak-core type" urban agglomeration. (2) Spatial reciprocity intensity between cities of Hefei is slightly higher than that of Wuhu and Ma'anshan and significantly higher than other cities. Hefei and Wuhu play a more important role in the urban agglomeration, and they are two most important nodes in urban agglomeration. (3) The spatial connection direction appears in a circle-shape which radiates externally around Hefei and expands along the traffic corridor in an axis including He-Xu and He-Chao-Wu expressway from south to north and along the Yangtze River expressway from east to west. (4) Spatial integration of urban agglomerations is achieved through the different stages of development of the regional development layout mode. According to urban flow strength spatial reciprocity intensity between cities, Jianghuai urban agglomeration should be a combination mode of "circle" and "T" types at present; when the long-term development of urban agglomeration is relatively mature, the "dual-core" type spatial integrated pattern can be gradually formed with Hefei and Wuhu as the center, hence Jianghuai urban agglomeration develops coordinately.
