基于城市流的中原城市群城市联系分析

以定量分析方法,对中原城市群的区位商、外向功能量和城市流强度进行计算分析的结果显示：中原城市群内城市之间外向服务功能差异不很明显,城市群发展空间较为集中,城市分工重叠,制约着经济社会的发展;郑州与其他城市联系不紧密,对整个城市群的辐射和带动作用不明显;城市群的交通仓储邮电业发展不理想。中原城市群的发展需注意以下几点：郑州作为区域中心城市,应加大对整个城市群的辐射和带动作用;进一步明确城市群内各城市分工;重点发展区域副中心城市,避免城市群内部等级明显分化;大力发展城市群的交通仓储邮电业;平顶山亟待提升对外服务功能,增强城市综合服务能力。

Analysis of the urban contact based on urban flows in Central Plains city group

The results of a quantitative analysis of the regional quotient,external function capacity and urban flows intensity of Central Plains city group show that factors such as no obvious difference in the external service function of the cities in the city group,concentrated development space of the city group and overlapped development of the cities restrict the economic and social development;problems such as no close contact between Zhengzhou and other cities,Zhengzhou’s driving function being weak and not well-developed transprotaion,storage and post and telecommunications industries exist.The following aspects should be paid attention to in the development of Central Plains city group：strengthening the driving role of Zhengzhou as a key city,further clarifying each city’s focus of development,focusing on the development of regional sub-key cities and avoiding differentiation among the cities,promoting the development of transportation,storage and post and telecommunications industries. Pingdingshan should improve urgently its external service function and strengthen its rural multiple service ability.
