基于三维尺度的中原经济区城镇化时空特征研究

基于可变面域和城镇化率指标,采用变异系数、泰尔指数和ESDA-GIS分析方法,从分区、市域、县域三维尺度分析了中原经济区城镇化发展的时空分异特征.基于研究结果对时序特征的变化趋势、空间分布和关联特征进行对比分析,并对尺度效应和异质性特征进行细化解释,旨在分析城镇化发展的内部分异状态,以期为中原经济区新型城镇化发展的定位推进和稳步前行提供理论参考.

A Case Study of Urbanization Spatio-temporal Characteristics of Zhongyuan Economic Region at Three Spatial Level

With the increasing availability of data,this paper employs coefficient variance,Theil index,spatial autocorrelation based on the urbanization rate to examine the changing trends and spatial patterns of Zhongyuan Economic Region at three different spatial scales,i.e.partition,city and county.According to the research results,this paper gives a comparative analysis on spatio-temprol characteristics at three spatial level and makes a evaluation on scale effect.We hope these results can provide some theoretical reference to new-type urbanization construction of Zhongyuan Economic Region.
