| 摘 要： | 运用区位商分析方法,对兰州-西宁-银川城市带8个地级市2002-2008年市区的旅客、货物运输资料分析,研究城市带区域城市间空间联系的分布特征,评价客、货运量在区域系统内各城市分布的均衡程度,及其时空变化特征。结果表明:自2002年以来兰西银城市带各城市间的空间联系呈现加强趋势,铁路旅客运输空间联系的加强趋势更为明显;2002年以来该区域客运量分布状况变化不大,货运量极化效应减弱,体现城市间的经济联系的变化特点。为进一步加强城市间的经济联系,推进城市带经济共同发展,要注重基础设施的建设,加强城市间的协调与支持。

| Abstract: | Based on the flows of passenger and freight transpot from 2002 to 2008 of every city in the Lanzhou-Xining-Yinchuan urban corridor,we analyzed its location quotient and summarizes the spatial features in this region.The results showed that the spatial linkage between cities of The Lanzhou-Xining-Yinchuan urban corridor has been improved since 2002,espatialy in raliway freight flow,and also that the flow of passenger distribution is still concentrating in Lanzhou,Xining and Yinchuan while the polarization effect of freight flow is weakening.Based on these characteristics,transport net-work should be constructed as soon as possible in Lanzhou-Xining-Yinchuan urban corridor;also the corridor economy with powerful diffusion force should be fostered.All these policies will promote the cooperation between administrative regions and realize integrated regional economy. |
