Composite Space Elements Under The Optimization Research Of The Action Tieling Town System Structure

Urban system is in a certain region within the scope of center towns as the core,by a series of different grades,different functional division of labor,with close ties between towns of organic whole.Scientific urban system structure is conducive to the rational allocation of regional resources,optimize the industrial layout,expand the investment benefit,promote the rapid growth of the regional economy.Long-term since,our country has many county level administrative units due to the unreasonable county urban system planning,result in unable to optimal allocation of regional resources,largely limits the county's economic development.Because at present the research of urban system often used quantitative analysis of urban system scale grade,the spatial structure,then use qualitative research the functions of the urban system,and finally puts forward some countermeasures for optimizing.Little systematic research on the basic factors that affect urban inner relationship between urban system and the related results.So it is necessary to build the influence factors of urban system of the measurement system,through the analysis of the ideas and methods system affect the space of urban system elements and building space coupling of collaborative relationship,reveal the spatial elements compound inner mechanism of urban system optimization.For the purpose of this article studies the theoretical basis of,and puts forward the concept of"compound effect" of space elements.The concept of space elements often mentioned in the regional economic geography.The concept of space elements often mentioned in the regional economic geography.As more closely and geographical spatial contact areas as a whole the development of the implementation of the policy,spatial elements in the regional economy is more and more significant.County town system is at the county level of regional space,analysis of the status quo of tieling county urban system,choose the influence of tieling county space factor and the system of the study of the characteristics of various elements in the county.For the characteristics of cognitive space elements,USES the quantitative analysis method,principal component analysis)and system analysis method is put forward "population-industry-land-evaluation index system of network infrastructure",of tieling county urban system in space were measured and compared on cross section.By analyzing the influence factors and coupling matching relation,put forward the countermeasures and Suggestions of tieling county urban system optimization,the main research content is as follows:1.Based on the interaction between urban space theory,regional economic geography theory put forward the influence area movement of the five elements are factors of population,industry factors,land elements and road traffic facilities,social factors.In order to further choose affect the quality of the urban system to provide theoretical basis.2.Analysis of tieling county urban system present situation existence question.Combined with the problems existed in the present situation and influence area movement of the five elements selection is four spatial elements of ticling county urban system.And further analyze the ticling county space factor influence mechanism,the space characteristics.3.Build coupling coordination degree model,analysis of population,industry,land,coupling coordination degree between the four essential factors of network space industry and pattern,and comprehensive analysis based on prlincipal component analysis(pca)score of tieling county township.Finally on the basis of coupling coordination degree,and the optimization of tieling county synthetically score countermeasures of urban system.
