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.

Key words: Jianghuai urban agglomeration, spatial combination, integrated patterns
