通道建设是丝绸之路核心建设的突破口,明确其城市空间结构是推动通道经济带建设的关键所在。本文基于城市空间理论,采用引力模型,利用ArcGis等软件,以三大通道18个主要交通节点城市为研究对象,通过计算2014年样本城市经济质量、距离、城市间引力以及城市间断裂点,发现:“乌昌都市圈”是超级增长极,长期呈现明显的“单核”集聚结构,北疆城市间引力明显强于南疆;北轴带的克拉玛依、石河子存在次中心争夺,而南疆三地州城市中心引力较低,缺乏有效的增长中心,同时东疆主要交通枢纽吐鲁番引力不足。最后针对现存的问题,提出了明确城市定位、加强道路管网的建设等对策建议。
Passage construction is a breakthrough in the core construction of the Silk Road. A clear definition of the urban spatial structure is the key to promoting the construction of the Passage Economic Belt. Based on the theory of urban space, using gravitation model and software such as ArcGis, taking the 18 major traffic node cities of the three major passageways as research objects, this paper calculates the city’s economic mass, distance, inter-city gravity and inter-city breakpoints in 2014, : “Wuchang metropolitan area” is a super-growth pole, showing a long-term “single core ” agglomeration structure. The gravitation between cities in northern Xinjiang is obviously stronger than that in southern Xinjiang. There is sub-center competition between Karamay and Shihezi in the northern axis, However, the gravity of the urban centers in the three southern states is relatively low, and there is no effective growth center. At the same time, there is not enough gravitation in Turpan, the major transport hub in the eastern part of Xinjiang. Finally, in view of the existing problems, this paper puts forward some countermeasures and suggestions such as clarifying the urban orientation and strengthening the construction of the road network.
