The spatial structure of city-region system is interactively affected with the coordination and comprehensive development,it is important to effectively promote the city in the city-region system to coordinate and sustainable development by integrating and optimizing spatial structure of city-region system.In Henan Province,it is an effective method to solve the problems of urban-rural and region,to enhance the comprehensive competition force of central urban agglomeration,Henan Province and central economic district and to promote the regional economic growth.This paper gives an analysis of spatial structure of city-region system by the methods of weighted voronio map,the distribution of city,spatial analysis and spatial interaction.The result shows that the urban influenced scope is unbalanced,the urban spatial relevance is not strong,the city spot of spatial distribution is random and even and the urban spatial interactive strength is in a large level variation.
