中蒙俄K3/K4次国际班列对沿线城市可达性的影响

Impact of K3/K4 Transnational Trains on Accessibility of Cities Along the Railway

以中蒙俄铁路K3/K4次班列沿线节点城市和区域为研究对象,分析了其节点城市与区域的可达性,并计算了节点城市之间的经济联系强度。结果表明,节点城市时间可达性呈现两端高、中间低的趋势,与节点城市到目的地城市的出行时间成正比;节点城市的经济可达性呈现两端低、中间高的趋势;K3/K4班列沿线有4个较明显的经济中心区,且中国城市之间的经济联系强度和俄罗斯西部城市之间的经济联系强度较高,此外中国与蒙古国之间的经济联系弱于蒙古国与俄罗斯之间的经济联系。受边境检查和转向架更换情况的影响,中蒙边境的二连浩特、扎门乌德和蒙俄边境的苏赫巴托尔、纳乌什基在上述计算结果中均表现出明显的特殊性。

Taking the node cities along K3/K4 train of China-Mongolia-Russia railway as research objects,we analyzed the accessibility,and calculated the economic connection intensity between node cities.The main results show that the average travel time of node cities shows a trend of high at both ends and low in the middle,this is directly proportional to the travel time from the node city to destination cities.The economic potential of node cities shows a trend of low at both ends and high in the middle.There are four obvious economic centers along the K3/K4 train and the economic connection intensity between cities of China and the western part of Russia are higher than the others.In addition,the economic connection between China and Mongolia is weaker than between Mongolia and Russia.Erenhot and Zamiin-Uud at the border of China and Mongolia,Sükhbaatar and Naushki at the border of Mongolia and Russia show particularity results.
