摘　　要：分析了淮海经济区城市体系的现状,其表现为城市体系比较完整,但首位度偏小,规模结构失衡;城市密度较大,空间分布相对均衡;城市分布的轴向特征明显.利用齐夫(Zipf)公式和关联维数对其城市等级规模结构、空间分布进行了研究,并对优化城市体系结构提出了几点建议:强化徐州一级中心城市的龙头作用;重点发展区域性中心城市;积极发展小城市;加快区域空间结构轴的建设;建立健全统一协调机制.Firstly,the paper summarizes the present situation of urban system in Huaihai Economic Zone, and some conclusions are drawn： Urban system is relatively perfect, but the urban primacy index is too small, scale distribution is lopsided; urban density is comparatively big, spatial distribution is fairly balanced; characteristics along axis direction of urban distribution are obvious. Then urban scale structure and spatial distribution are studied by using Zipf rule and correlation dimension. Some proposals are put forward for the optimization of urban system, such as strengthening leading status of Xuzhou as primary central city; emphatically developing regional central cities;actively developing small cities and quickening the construction of regional spatial structure axis;establishing and perfecting the unified and coordinated mechanism.
