连云港市的双核结构与区域发展探讨

连云港市呈现出典型的一市双城式空间结构。研究表明,该市的这种由市区与港口组成的双核结构,历史上曾经有三种不同的组合,即海州与新浦、新浦与大浦、新浦与连云。海岸线的东移、铁路等现代交通方式的影响,以及河海相交的区位优势等是造成不同时期形成不同双核结构的主要原因。对其演化过程与形成机理进行深入分析,不仅有助于探讨该市今后城市空间结构的演化趋势,也为双核结构模式的机理分析,提供一个典型的案例。

THE STUDY ON TWO-CORE STRUCTURE AND REGIONAL DEVELOPMENT OF LIAN YUNGANG CITY

The city of Lian Yungang has a typical structure of "one city, two towns". This two cores-structure, composed of downtown and the port had three different constitutes in its history. They are Haizhou-Xinpu, Xinpu-Dapu, Xinpu-Lianyun. In view of the cause of formation, the evolution process of the relationship between port and city in Lian yun-gang is also the process of the port moving the east constantly. And the port moving the east is because of the coastline moving the east, namely Shu river delta continually. Based on the above analysis, the author thinks that the core of the city of Lian Yungang will be the area of Xinhai in the coming days. So it is a correct policy to keep the area of Xinhai as the core of the city of Lian Yungang. In brief, the author regards that the deep analysis about evolution processor and formative mechanism of the two-core structure of the Lian Yungang city not only contribute to the study of the evolution stream of civil spatial structure in the future, but also provide a typical example that study the mechanism of the two-core model.
