Research On Structural Character Of Urban Agglomerations In Guanzhong-Tianshui Economic Area

Urban agglomeration is a kind of regional spatial organization form appeared in process of urbanization, is a senior phenomenon of urban agglomeration and urban diffusion. Urban agglomeration has become one of the main trends in the developed countries. Since the 1980s, with the development of the west regions of China, the economy of the west regions of China has greatly improved, while the city develop has entered a rapid growth phase. The State Department approved the <Guanzhong-Tianshui Economic Area Development Plan> in 2009, Guanzhong-Tianshui economic area is identified in <Development of the West Regions " Eleventh Five-Year "Plan> as one of three key economic zones. Shaanxi province is the first phase in the western development of developing western region, Xi'an as the center of the Guanzhong region is leading the development of the western region, Guanzhong-Tianshui economic area is the key areas of economic development in the northwest. The structure character of urban agglomeration in Guanzhong-Tianshui economic area accelerate the continual development of the regional economic as well to research the urban agglomeration, spatial structure evolution and its spatial allocation modes deeply.Make an analysis from three aspects of scale structure, function structure, spatial structure of urban agglomeration in Guanzhong-Tianshui economic area, using the theory about development in urban agglomerations for reference. Expatiate on the research backgrounds, research purposes, and the research train of thoughts as well as research methods of this paper. Read the large number of documents, make an analysis of concept of urban agglomeration. Introduces the scope, population, resources, social and economic development urban agglomerations in economic area Make a concrete analysis from the city of the scale structure, function structure, spatial structure of the urban agglomerations,using of mathematics methods and associated data.Make a suggestion about aspect of develop to structure of the urban agglomerations, according to the analysis results. Integrate of the original small town, enhance center promotes town radiation, come into being large, medium, small towns proportion appropriate town scale system; Determine the industry has the advantage in economic zone, improve the quality of industrialization in economic zone, accelerate the convergence speed between industries; Construct spatial development system from "two unclear, one axis, three radiation ".
