河南省城镇体系规模结构时空特征分析

Study on the Spatial and Temporal Characteristics of the Scale Structure of the Urban System in He'nan Province

综合应用城市首位率、不平衡指数和分形模型对河南省城镇体系从城镇人口和省辖市市区非农业人口两个层面研究其规模和空间结构时空演变特征。得出了省辖市市区非农业人口较之统计中的城镇人口更能表征城市实际规模和河南省城镇体系规模结构总体上表现出不平衡性的结论。建议完善统计分类,以市区常住人口作为衡量城镇人口的规模;河南省应进一步提升首位城市郑州的中心地位,并构建等级规模体系完整,空间结构布局合理的现代城镇体系。

The paper integrated application of urban primacy rate,imbalance index and fractal theory of the urban system in the provincial cities from the urban population and urban non-agricultural population to study the temporal evolution of the two levels of features.The results show that： the provincial cities non-agricultural population is more accurate than the urban population to statistical characterization;the structure of the urban system in He＇nan Province shows imbalance on the whole.The paper proposed to improve the statistical classification of the resident population to urban areas as a measure of the size of the urban population;Zhengzhou City should further enhance the center of the first,and build a complete system of rating scale,spatial structure,rational layout of the modern urban system in He＇nan Province.
