Research On City Spatial Expansion Of Shenyang Based On Element Flows

Presently, the urbanization process of our country is in a special historical period.According to the developmental law of urbanization, we can see that the urbanizationof our country will enter a new stage. City spatial expansion will become the researchemphasis of City Geography, City economics, and so on.Facing a series of social and economic problems caused by city spatial expansionof Shenyang, and starting from the fundamental concepts about city spatial expansion,this research takes city elements flow theory, city internal spatial diffusion theory, andcity output theory as guidance, makes use of GIS space analysis methods and RSimage treatment methods, and chooses quantitative index to analyze the process ofcity spatial expansion of Shenyang; and then analyze the mechanisms of city spatialexpansion of Shenyang from the perspective of city elements flow; finally put forwardregulation countermeasures to counter the existed problems.This artical consists of theoretical and empirical analysis:In the theoretical part, this paper includes exordium in the first part and basictheory of city spatial expansion. The first part introduces the research background, thegoal the significance, the overall train of thought, method and the logical framework;the first part introduces theoretical basises, including related concepts discrimination,city elements flow theory, city internal spatial diffusion theory, and city output theory.In the empirical part, this paper includes the process of city spatial expansion ofShenyang in the third part, the mechanisms of city spatial expansion of Shenyang inthe forth part, regulation countermeasures to counter the existed problems in the fifthpart,and conclusions in the last part. The third part introduces the regional generalsituation, data source and processing, and then mainly analyzes mode, efficiency,characteristics and effects of city spatial expansion of Shenyang; the forth partanalyzes the mechanisms of city spatial expansion of Shenyang from the perspectiveof city elements flow; the fifth part puts forward regulation countermeasures tocounter the existed problems.
