扬子江城市群空间结构演变与支撑策略研究

STUDY ON SPATIAL STRUCTURE EVOLUTION AND SUPPORTING STRATEGIES OF YANGZIJIANG URBAN AGGLOMERATION

基于GIS平台,运用位序规模分布、均匀度指数、引力指数对扬子江城市群空间结构演变、集聚扩散特征、空间相互作用强度进行分析,结果如下:南京、苏州中心城市辐射带动区域发展能力有限;泰州中轴枢纽优势未充分发挥;南通江海门户地位未充分利用;跨江基础设施对接不足均在一定程度上阻碍了扬子江城市群的发展。未来应强化苏州、南京双引擎功能,实现扬子江城市群双核共振式发展;优先实现发展洼地隆起,带动城市群带状连绵式发展;加强跨江通道建设;重视泰州中轴培育。

Based on GIS platform, Use the Evenness index, Gravity index and Rank - Size Rule to analyze the characteristics of agglomeration and diffusion, the intensity of spatial interaction, the hierarchical structure and other spatial structural features. Result found - The central city of Nanjing and Suzhou have limited capacity for re- gional development. The advantages of Center pivot of Taizhou is underdeveloped, the status of the river and sea portal of Nantong is not fully utilized. Insufficient infrastructure across the river, which hinder the development of he Yangtze River Urban Agglomeration. In Future, Strengthen Suzhou, Nanjing dual engine function, to achieve the dual - core resonant development. Give priority to the development of depression to promote the urban agglom- eration to develop as belt - like modle. Strengthen cross - river channel construction, Pay attention to the develop- ment of Taizhou.
