摘要
运用地理分形理论研究了河南省城市化过程中城市体系等级结构变化的基本特征。借助分维揭示了城市规模分布的集中化倾向，然后通过ｑ－函数反映了Ｚｉｐｆ维数下降引起的损益。文章认为，系统等级结构优化的关键在于两点：①改善城市位序—规模的分形性态；②Ｚｉｐｆ维数保持在ｑ≈１的自然水平。
The change trend of hierachical structure of urban system in Henan during the urbanizational course was analysed with geo-fractal theory.It was found that the Zipf's dimension of the size distribution of cities in the study district was decreasing,this meaned that the urban population in different cities was becoming equal,which would give rise to some advantages and some disadvantages as well,the pros and cons from the increase of the fractal dimension were discussed by means of q-function advanced by the second author.Finally,it was pointed out how to solve the problems mentioned and improve the hierarchy of the urban system of Henan Province.
