Study On Optimizing The Structure And Function Of Urban System In Central Henan Urban Agglomeration Area

Urban system is an abstract description of an organization and spatial relationship in an urban agglomeration, and it is important contents of urban geography. With the development of economic globalization, the connection between cities is closer day by day, and the forming of the city group is an inexorable trend. Urban system study is an key link of realizing area driving strategy, and it is particularly important to realize urban agglomeration benefit as a whole. In order to meet the new demand that the fast social and economic development of our country puts forwards, we must accelerate urban system study of urban agglomeration under the new situation. At present, Henan Province has already formed a urban agglomeration which takes Zhengzhou city as the center, including Luoyang, Kaifeng, etc nine cities and 14 county-level cities. The central Henan urban agglomeration will become the main carrier to accept the industry's gradient shifted. It may become the "platform of central Henan" with important and strategic significance on Chinese economic domain in the future. However, some problems exist in the urban systems of this area, mainly showing in the following aspects: the inside structure is unreasonable, lacking the rational city division; mutual connection isn't close, having not formed ordering and networked urban system structure yet. These problems must cause functions reduction of the central Henan urban agglomeration as a whole, so the area development is relatively slow. In order to structure an orderly and high-efficient urban system and perfect the urban system function, we must optimize the structure and function of the urban system in this area. This paper mainly includes several following parts: Part I, introduction. According to the current problems of the city system structure and functions of the central Henan urban agglomeration, this part puts forward the necessity of research. On the basis of review in domestic and international urban system study, this part proposes the main research contents of this paper according to this area condition. Part â…¡, systemic analysis of research theory and method of urban system. Through carrying on systematized analysis to the theory and method, this part explores the relation among relevant theories to start the study easily. Part â…¢, study on optimizing the hierarchical structure of urban system in central Henan urban agglomeration. This part uses relevant theory and method to analyze current hierarchical structure situation of urban system in this area, put forward optimizing project according to the existing problem. Part â…£, Part â…¤and Part â…¥, study on optimizing the urban system from three structures of scale, function and spatial arrangement. These parts find out weakness of urban system in this area through current situation "three kinds of structures" analysis, and carry on corresponding optimization according to the level frame of the grade of urban system. Part â…¦, study on optimizing the function of urban system in central Henan urban agglomeration. On the basis of optimizing the urban system structure put up in advance, this part gives the mode of circle layers and the network mode to organizing cities, and provide countermeasure that the function can be realized and advanced. Part â…§, conclusion.This part generalizes the reviews and the shortages of this reserch.
