摘要:: 城市规模增长次序及协调性研究对理解城市化过程和制定区域发展政策至关重要。基于城市空间不透水地表数据，对1990—2018年长三角地区26个地级以上中心城市用地规模增长和协调性进行系统分析。结果表明：长三角地区中心城市规模增长次序基本符合顺序增长模式，优先增长的是特（超）大城市，其次是大城市和中小城市，长期来看，长三角地区城市规模分布演化呈现为收敛式增长。长三角地区大多数中心城市用地增长与人口、经济协调性较好，城市空间发展质量总体水平较高。未来城市发展政策制定应顺应城市规模增长的动态演化规律，促进大中小城市的规模和功能协调；针对城市用地协调程度和类型，采取差异化的城镇发展策略，推动城市空间高质量发展。

Abstract:: The research on the order and coordination of urban scale growth is very important for understanding the urbanization process and formulating regional development policies. Based on urban impervious surface data, a systematic analysis of the growth and coordination of land use scale in 26 central cities in the Yangtze River Delta region from 1990 to 2018. The results show that: ① The growth order of central cities in the Yangtze River Delta basically conforms to the sequential growth model, with the priority given to the growth of megacities, followed by large cities and small and medium-sized cities. In the long run, the evolution of urban size distribution in the Yangtze River Delta region shows a convergent growth trend. ② The land use growth of most central cities in the Yangtze River Delta is well coordinated with population and economy, and the overall quality of urban spatial development is high. The formulation of future urban development policies should conform to the dynamic evolution law of urban scale growth and promote the coordination of the size and functions of large, medium and small cities; According to the coordination degree and type of urban land, the differentiated urban development strategies should be adopted to promote the high-quality development of urban space.
