基于浙江省县域单元城市人口数据,运用位序—规模法则、分形理论、GIS等计量方法从时、空间角度分析浙江省城市规模体系演化特征.研究结果表明,(1)浙江省城市规模结构总体不断调整优化,问题在于特大城市、大城市数量稍显不足;(2)浙江省城市规模体系发育经历了小城镇快速发展和大城市加速发展两个阶段,杭州市的首位度也呈现出下降和上升两个阶段;(3)空间演变上,沿海和内陆城市区域差异显著;环杭州湾地区、温台沿海地区、金华—义乌地区日益显现出圈层集聚特性.
Based on the urban population data of county-level cities in Zhejiang Province, this paper analyzes the evolution characteristics of urban scale system in Zhejiang Province from the spatial and temporal perspectives using the method of order-scale, fractal theory and GIS.The results show that: (1) Constantly adjust and optimize the problem lies in megalopolis, the number of metropolitan slightly less; (2) The development of Zhejiang’s city scale system has experienced two stages of the rapid development of small towns and the accelerated development of large cities, Hangzhou City, the first degree also showed a decline and (3) Spatial evolution has significant differences between coastal and inland urban areas. The characteristics of the ring formation are increasingly appearing in the coastal areas around Hangzhou Bay, Wentai, Jinhua and Yiwu.
