中文摘要：

通过构建城乡发展协调性量化评价指标体系，运用主成分分析方法定量测度了淮河流域29个地级市城乡发展的协调程度，并探讨其空间分布特征。结果发现：淮河流域城乡发展协调性空间差异特征显著，以郑州、扬州、徐州（济宁）连线成三角形的顶点区域城乡发展协调水平最高，三边区域次之，中心区域最弱；城乡协调程度与经济发展水平基本呈正相关关系，经济发展水平越高，其城乡协调性越好；淮河流域城乡协调程度可以分为协调型、基本协调型、濒临失调型、失调型和严重失调型5种类型。

英文摘要：

Based on the construction of index system of urban-rural development coordination evaluation, the urban-rural coordination development index of 29 prefecture-level cities in Huaihe river basin were measured quantitatively through the principal component analysis, and its spatial distribution characteristics were explored. The result showed that the spatial difference of urban-rural development coordination is evident in Huaihe river basin. If make Zhengzhou, Yangzhou and Jining as a tringal’ s three vertices, the highest level of urban-rural coordination degree is vertices region, followed by sideline areas, and the lowest level lies in central region. It is clear that the relationship between urban-rural coordination and economy development level is positive, and the higher economy development level, the better urban and rural development coordination. Finally, this paper classifies 29 prefecture cities in Huaihe river basin into five types, which is , coordination, basic coordination, border on maladjustment, maladjustment, and severe maladjustment.
