摘　　要：以行政区划全在淮河流域范围的26个地级城市为基本研究单元,对其产业结构、客运总量水平、对外交通设施网络的匹配程度进行分析,结合26个城市城市化水平、城镇职能、空间结构等特征,运用城市空间相互作用计算模型初步确定了整体淮河流域的中心城市,并基本勾勒出整体流域的空间结构优化路径.最后指出,淮河流域水系、区位等地理要素的过渡性、多变性对流域整体城镇群体的集聚—扩散功能具有阻滞作用.Taking the 26 prefecture-level cities ：as fundamental unit which completely belongs to the Huaihe River basin in administration to explain industrial structure, passenger volume and transportation facilities of 26 prefecture- level cities, the core city and urban spatial system planning for the whole Huaihe River basin is presented through the analysis of urban spatial interaction among 26 cities according to the level of urbanization, city function and spatial structure of 26 cities. The model of structural planning is grounded on the combination with spatial distribution pattern and measurement of interaction strength. Finally, the changeable characteristic of water system and location of the Huaihe River basin have a deep retardative effect on the agglomeration and diffusion mechanism of urban group.
