摘　　要：以中原经济区为研究区域,在对城市中心性相关理论梳理的基础上,建立了城市中心性评价指标体系,并运用主成分分析法、加权Voronoi图分别对中原经济区城市进行中心性评价、城市空间影响力分析.结果表明,中心性强度高的城市集中在京广线及其以西地区,且中心性等级类型齐全;京广线以东地区城市中心性等级普遍较低,主要分布有第Ⅲ级、第Ⅴ级类型;在城市空间影响力上,中原经济区和次区域的中心性强度呈现由中心城市向外围城市递减的特征.据此,并考虑区位条件、交通中介、空间关系等因素,将中原经济区划分为1个Ⅰ级城市经济区、3个Ⅱ级城市经济区和4个Ⅲ级城市经济区.T he paper firstly review s the study progress on urban economic region , then constructs the index system of urban centrality evaluation , and measures the urban centrality by using principal component analysis（PCA） and min‐max normalization ,analyses the spacial influence of urban by using voronoi weighted voronoi diagram . The results show ：these urbans with high centrality are focused on the Beijing‐Guangzhou railway line and its west region , and centrality level types are complete . Urban centrality in the Beijing‐Guangzhou railway line east region is usually not high , these urban centraliy level types are the third grade and the fifth grade . On influence of urban space , centrality strength values of urbans in central plains economic region and its sub‐region show a distance attenuation characteristics from the central urban to theperiphery . Accordingly , and taking into account factors such as geographical conditions , transportation intermediaries , spatial relationships , Central Plains economic region is divided into 8 subregions .
