摘要 基于核密度分析、网格维数和热点分析法等方法,以我国新增县级市为研究对象,选择1985年、1991年、1997年和2017年4个时间截面,探讨了其时空演变的多维特征和影响机理。结果表明:(1)我国县级市在时间演化上历经了探索起步、稳步增长、快速提升和缓慢发展四个阶段,总结了县级市设置的六种主要模式。(2)在结构特征上,县级市设置呈现出由均衡分布趋向集中分布的发展态势,具有分形特征明显和分形结构较为复杂的特征。(3)在空间分布格局上,县级市设置的集聚程度先上升后下降,由均衡分布向东、中部地区集聚再向西部地区侧重转变。(4)在热点区分布上,冷热点区迁移特征显著,其中热点区发展路径为“内陆地区—东部沿海地区—西部地区”。(5)在影响因素方面,城市化和政策导向是县级市设置演变的主要驱动力。 Based on nuclear density analysis,grid dimension and hotspot analysis,the new county-level cities were selected as research objects,and three time sections of 1985,1991,1997 and 2017 were selected to explore the multi-dimensional characteristics of the temporal and spatial evolution and the mechanism of influence.The research results showed that: ①County-level cities in China experienced four stages: Exploration,steady growth,rapid improvement and slow development in time evolution,and summarized six main modes of setting up county-level cities.②In terms of spatial structure characteristics,the county-level city setting showed a trend of development from a balanced distribution to a concentrated distribution.In addition,the fractal features of county-level cities were obvious and the fractal structure was more complex.③In the spatial distribution pattern,the degree of agglomeration set by the county-level cities first rises and then falls,and the equilibrium distribution shifted to the eastern and central regions and then to the western regions.④ In the distribution of hotspots,the characteristics of cold hotspots were significant,and the development path of hotspots was“inland areas- eastern coastal areas-western areas”.⑤In terms of influencing factors,urbanization and policy orientation were the main driving forces for the evolution of county-level cities.
