Abstract: 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.
