港口与城市规模关系的评价与比较——以辽宁省港口城市为例

立足于城市地理学视角,以港口与城市规模关系为切入点,以辽宁省6座港口城市为案例,从宏观和综合的角度考察港口城市的发展程度及发展过程特征。引入RCI指数作为评价港口城市港口与城市规模关系的指标,判断港口城市类型与阶段演进。研究认为:①2008年,辽宁省港口城市包括三大类型,其中,大连市为具有典型港城特征的大区域级门户城市,营口市为特征显著的区域级门户城市,锦州市和丹东市为港口功能显化的区域级临海城市,盘锦市和葫芦岛市为港口功能相对弱小的区域级一般城市;②近10 a间,辽宁省港口城市港口与城市规模关系变化呈现出4方面特征,即大连市由门户城市向典型港口城市类型发展,营口市由典型港口城市转变为特征显著的门户城市,锦州、丹东、葫芦岛和盘锦四市作为港口城市发展缓慢,营口市和丹东市港口与城市规模关系实现了阶段跨越。

Evaluation and Comparison of Size Relationship Between Port and Port-city:Taking the Port-cities of Liaoning Province as Example

This paper studies the size relationship between port and port-city,and the research objects are the six port-cities of Liaoning Province,China.It tries to study the development level and the evolution characteristics of the port-city from the macroscopic and comprehensive perspective.The RCI index is employed to evaluate the size relationship between port and port-city,and then judge the port-cities′ category and evolution stage.Results show that: for one thing,there are three major port-city categories in Liaoning Province in 2008.Dalian is regional gateway city in large-scale and with the characteristics of typical port-city.Yingkou is remarkable regional gateway city.Jinzhou and Dandong are regional maritime cities which display port functions.Panjin and Huludao are general cities whose port functions are relatively weak.For another thing,in the recent ten years,the evolution of the size relationship shows four sides: first,Dalian is in the stage of developing from a gateway city to a typical port-city.Second,Yingkou has transformed from a typical port-city to a remarkable gateway city.Third,Jinzhou,Dandong,Huludao and Panjin have been developing slowly.Fourth,Yingkou and Dandong have realized the periodical leap-frogging development.
