江苏沿海地区港城耦合发展的动态测度与分析

Dynamic Measurement and Analysis of the Coupling Development of Jiangsu Coastal Cities and Ports

港口与城市规模关系是评价港城耦合发展的重要指标。以江苏沿海地区为研究对象,运用相对集中指数定量评价港城耦合发展的动态状况。研究显示:江苏沿海地区港城耦合发展存在明显的差异性和多样性。城市类型可分为门户城市、典型港城及临海城市;变动趋势呈现先上升后下降、持续稳中下降以及持续稳中上升等特征。

The relationship between port and city scale is an important index to evaluate the coupling development.Taking Jiangsu coastal area as the research object,the RCI indexes were used to evaluate the dynamic state of the coupling development.It shows that the coupling development of Jiangsu coastal areas and ports has significant differences and diversity.City types can be divided into portal city,a typical city and coastal city.The change trend display three features:initial ascending and then decline,continued steady decline and continued steady rise.
