辽中南城市群城市流分析与模型阐释

基于城市流理论,城市流强度的分析方法,对辽中南城市群各城市的区位商、外向功能量、城市流强度及其结构进行了分析与测算,并与国内部分城市群城市流相关指标进行了比较.结果表明:除沈阳、大连外,群内其他城市的城市流强度值均较低;一些资源型城市的城市流强度值甚至为0;城市总体经济实力与城市流倾向度的相对比例关系不够协调;城市群结构不优,一体化程度不高,整体功能不强等,并利用SPSS软件对辽中南城市群城市流强度模型的影响因素进行了回归分析,在此基础上,提出了几点优化对策.

ANALYSIS OF URBAN FLOW AND MODEL EXPLANATION ON THE URBAN GROUP IN MIDDLE-SOUTH PART OF LIAONING PROVINCE

Based on the urban flow theory,analytical method of the intensity of urban flow for the urban group in middle-south part of Liaoning province of the territorial quotient for the main extrovert service,the extrovert energy,the intensity of urban flow and its structure to carry through analysis and calculations,and with the part of domestic urban group of the related indicators of urban flow were compared.The results showed:Apart from Shenyang,Dalian,the intensity of urban flow values of the other cities within groups were lower,intensity of urban flow of some resource-based cities are even to the value 0;the overall economic strength and the degree of tendency of urban flow of relative proportions uncoordinated,the structure of urban group is not well,the degree of integration is not high and overall function is not strong;And use SPSS software to carry through regression analysis to the factor of the model of the intensity of urban flow for the urban group in middle-south part of Liaoning province.On this basis,the corresponding optimal strategies were put forward.
