中文摘要：

采用GIS、Matlab和数据库等技术手段，构建城市联系网络，一定程度上突破了传统方法对城市关系的研究，以2007年和2011年的Topl、Top3和Top5网络为例证进行研究．结果表明：中原经济区分为五大片区，即中部核心增长区、北部城镇协调区、西北部城镇协调区、豫皖交界处的东部城镇协调区、南部城镇协调区；从Top3、Top5网络和聚类系数的变化来看，中原经济区是以郑州为核心，但整体集聚力较差，辐射能力较弱，内部各城市发展不均衡，连接不够紧密．据此，提出了服务于中原经济区建设的相关政策建议．

英文摘要：

Through research on the current urban system, and we created the urban network linked by basic activities among the cities of Central Plains Economic Region at the prefecture level, by employing the technical tools such as GIS, Matlab and database analysis to build the city network of contacts, to some extent. This paper broke the traditional hierarchical-and-order perspective. Finally, using the data of 2007 and 2011 to create the network of topl, top3 and top5 （the maximum of urban linkages, the first three, the first five） as the examples to study. The results showed that： the Central Plains Economic Zone is divided into five major area, such as the central core growth areas, the coordination area of northern town, the northwestern town, the eastern town of the junction of Yu-wan and the southern town. In comparison with the network and cluster coefficient of top3, topS, it showed： The center of Central Plains Economic Region is Zhengzhou. The economic links among cities in Central Plains Economic Region is not quite close. The total concentration and radiation is weak. The development is uneven among the cities. Accordingly, some suggests are proposed to service the development of Central Plains Economic Region.
