在城市群越来越演化为多尺度、多区域复杂系统背景下，有必要引入多分形理论与方法研究其空间结构。本文基于2018年NPP-VIIRS夜间灯光数据，计算长江中游城市群整体及其局部的多分维谱，根据谱线分析不同尺度下长江中游城市空间结构的多分形特征。结果显示：（1）长江中游城市群夜间灯光容量维在整体和局部都出现双标度现象。（2） q ＜-5.5时，整体广义关联维谱线突破理论上限2，在q＞ 0时，武汉城市圈和环长株潭城市群的分维显著较高。（3）整体的局部分维谱和武汉城市圈、环长株潭城市群、环鄱阳湖城市群、宜荆荆城市群局部分维谱表现为单峰偏右。根据上述结果，得到和验证了以下结论：（1）...

Nowadays, urban agglomerations are increasingly evolving into multi-scale, interregional complex systems. Therefore, it is necessary to apply a multi-fractal method to analyze the global and local properties of an urban agglomeration. Based on the NPP-VIIRS nighttime light data in 2018, this paper calculates the multi-fractal spectrum of urban agglomeration in the middle reaches of the Yangtze River (MRYR) and its four sub-agglomerations, and then analyzes their multi-fractal properties from the perspective of scale. The main results are as fol...
