【摘要】：利用改进引力模型并结合GIS方法,分析2000年以来南京都市圈县域尺度空间相互作用的时空演变,探讨圈域发展的问题与对策。结论如下:南京都市圈县市空间联系强度不断增强,南京主城与其它县市相互作用强度最高,其次为沿江各县市间、地级市主城区与其郊县间,南京、扬州、镇江、马鞍山等所辖县市间出现了联系强度较高的网络,有一体化发展趋势;历年县市潜力值都由最高峰的南京主城区为中心向四周递减,呈圈层式结构,在向外扩展过程中存在空间变异性,高潜力区沿江伸展,随着圈域内其它地区的发展,单一核心的结构开始发生变化;最后总结都市圈发展过程,提出圈域一体化发展的政策、交通、产业措施。
[Abstract]:Based on the improved gravity model and GIS method, the spatial and temporal evolution of spatial interaction in Nanjing metropolitan area since 2000 has been analyzed, and the problems and Countermeasures in the development of the circle have been discussed. The conclusions are as follows: Nanjing metropolitan counties spatial connection strength unceasingly strengthens, the main city of Nanjing and other cities the interaction strength is the highest, followed by the counties along the Yangtze River City, main city of the prefecture level city and suburban counties, Nanjing, Yangzhou, Zhenjiang, Ma'anshan and other cities and counties under the jurisdiction between the connection of high strength network, has integrated development trend; the potential value by the counties of the peak of the Nanjing urban area as the center decreases to around, is a circle structure in the outward expansion of the spatial variability of the process, along with the development of high potential areas stretching, circle within other areas, the structure of a single core began to change; finally summarizes the development process of metropolitan area. The development of region integration, transportation industry, policy measures.
