The key to make scientific decision and to promote soundly and rapidly regional economic and social development is to optimize the urban spatial structure. Based on social and economic data of Zhoukou City, Hehan Province, from 1995 to 2010 and technical analysis such as town construction land area and urban population growth strength index, this article states the present urban development of Zhoukou City: low level of regional urbanization, under-developed urban center, equilibrium development of town layout and integrated urban built-up area of Zhoukou City and Shangshui County. Then, the study deeply analyses the mechanism of urban spatial structure evolution and the trend of center polarized and fan-shaped wild goose queue type circle-layer network evolution orientated by transport and led by characteristic industrial clusters. Finally, it puts forwards related countermeasures: to scientifically plan the regional urban system, to essentially boost the unity of Zhoukou City and Shangshui County, to rapidly form the characteristic industrial clusters, to orderly promote the circulation of rural land, to advance the coordinated development of urbanization, industrialization and agricultural modernization and to enhance the construction of ecological towns in order to optimize Zhoukou urban spatial structure.
Key words: Zhoukou City; urban spatial structure; growth pole; compound city
