新亚欧大陆桥桥头堡区域空间格局重构研究

Spatial Re-construction of New Eurasian Continental Bridgehead Area

新亚欧大陆桥桥头堡区域的开发是江苏省“三沿”开发战略之一,也是我国沿海地区全面崛起的重要突破点。分析认为,区域内中等城市缺失造成城镇体系失衡,交通轴线局限于横向发展,纵向扩展受约束,县城经济中部断裂,空间差异十分明显,徐连两市难以支撑整个产业带的经济发展,提出了桥头堡区域应以科学发展观为指导,建立以中点新沂为核心的多层次双核结构模式,形成第一层主双核结构——徐连双核、第二级小双核结构——“新邳”、“新宿”、“新临”小双核,构成十字形空间结构体系,支撑区域经济与社会和谐发展。

The development of the new Eurasian Continental Bridgehead area is not only one of the ＂threeline＂ key developing strategies, but it is also the very area that hinders the overall rising of the Eastern coastal areas in China. Analysis shows that the lack of medium-sized cities has resulted in the unbalance in the city-town system. Besides, the development of transportation is limited horizontally;in consequence, economic relations among different counties are segmented. Moreover, the vast spatial differences in this area make the major two large cities, Lianyungang and Xuzhou, hard to promote the economic development in the whole area. In this respect, this paper proposes that we should guide economic development by the Scientific Development Outlook, and construct a two-nucleus city structure to form a cross-shape spatial city system and promote the economy and society to develop in a harmonious way.
