Spatial Coupling between Transportation Superiority and Economy in Central Plain Economic Zone
以中原经济区各县为对象，评估交通优势度（路网密度、可达性、区位优势）并与经济发展水平做耦合协调分析，发现交通超前于经济、协调度偏低，对区域规划有参考价值。
Taking the evaluation model of transportation superiority degree including transport network density,accessibility and location superiority three aspects,county level transportation superiority is evaluated and compared in Central Plain Economic Zone(CPEZ) in 2008.And then,based on the comprehensive evaluation of county's economic development,coupling and coordination degree between transportation superiority and regional economic development are measured and classifications of coupling-coordination regions are divided.Results show that:regional disparity of transportation superiority was remarkable and the circular stepped spatial pattern of transportation superiority that reduced gradually from Zhengzhou to the margins had appeared.Regional disparity of county's economy was also remarkable;Northwestern were higher than the southeast,mountainous resources counties were higher than plain agricultural counties.Although the coupling degree between county transportation superiority and economic development was high,the coordination degree between transportation superiority and economic development was lower than the coupling degree;most counties remained with middle and reluctance coordination state,only a few remained with high coordination state.The transportation infrastructure of most counties were ahead of regional economic development,just a few margin counties in the northwest were insufficient.The transportation superiority should be fully used to speed up county economy and to realize high level of coordination between transportation and regional economic development.
