以中原城市群县域服务业为研究对象，通过空间自相关、插值分析和标准离差椭圆方法，对2002—2013年中原城市群服务业水平空间格局特征进行分析.结果表明：①中原城市群服务业空间集聚程度由强减弱，高水平区与低水平区呈分散的集中分布趋势.②总体上服务业空间差异较大，中心外围结构明显，形成了以郑州、洛阳、新乡为核心的多中心空间结构；东部和南部地区服务业发展较慢，核心城市服务业带动作用不显著，要加快其辐射引领作用.③中原城市群服务业以郑州为中心，呈现沿长轴方向扩张，短轴方向收缩的趋势，呈较小的西南—东北分布模式，主要向洛阳、新乡、开封方向扩张，反映了郑—汴—洛及郑—新一体化进程的加快.%This article used the spatial autocorrelation,interpolation analysis and standard deviation ellipse method on the county service industry of Zhongyuan Urban Agglomeration to analyze the spatial differences of service industries in 2002-2013. Conclusions can be drawn as follows:①The characteristics of spatial agglomeration of service industry in the Zhongyuan Urban Agglomeration were weakened,the high level areas and the low level areas were distributed in the concentration distribution trend.②Overall,the spatial differences of service industry were becoming bigger and the structure of core periphery was obvious,formed a spatial structure of multi center in Zhengzhou, Luoyang and Xinxiang as the core. The development of service industry was slow in the eastern and southern regions. The leading role of service industry was not significant in those core cities and should be sped.③Distribution pattern of service industry of Zhongyuan Urban Agglomeration in Zhengzhou as the core ,presenting a trend of expansion along the long axis and a trend of contraction along the short axis. The small distribution pattern was“Southwest-Northeast”and the expansion had a trend to Luoyang Xinxiang and Kaifeng,showing that the process of the Zheng Bian Luo and Zheng Xin integration were speeding.
