摘要
采用1990—2008年的城市人口数据,首先对东北地区城市规模级别结构演变概况进行研究,在此基础上引入城市首位指数、位序—规模法则、城市基尼系数对地区城市规模分布演变展开计量分析,并进一步探讨了区域城市规模成长的空间特征。结果表明:东北地区城市规模等级结构呈阶段性、层级递进式演变;由于缺乏龙头带动城市,各城市首位指数较低且不断下降;1996—2008年,城市体系符合位序—规模法则,城市规模分布总体趋于合理;1990—2005年,经济基尼系数与人口基尼系数发展方向背道而驰,地区大城市、特大城市仍有较大的人口发展空间;区域城市规模成长表现出空间极化、轴线指向、群带集聚、区域差异等空间特征。
The paper collected the data of urban population from 1990 to 2008 for each city in Northeast China.Firstly,analyzed the evolution of city scale grade structure in Northeast China,then adopted city primacy index,rank-size rule,city Gini coefficient to analyze the rule of city scale distribution evolution quantitatively,and summarized the spatial characteristics of city size growing.The results showed that： ① the evolution of city scale grade structure had two characteristics of phased and successively increasing;②Shenyan as the primacy city did not have strong monopoly function,city primacy index were low and decreased gradually;②regional city system fitted to the rank-size rule since 1996,and city scale distribution tended to be reasonable;④population Gini coefficient and economic Gini coefficient showed different trend of development from 1990 to 2005,big cities still has large development space;⑤spatial polarization,axis direction,group and belt gathering,regional disparity were the main spatial characteristics of city scale growth in Northeast China.
