摘要(Abstract)：

科学评估重大突发公共卫生事件的空间影响是提升城市韧性的重要基础。为探究COVID-19疫情对城市空间及时空异质性影响，文章基于NPP-VIIRS夜间灯光数据，采用辐射亮度总值、时序差值及散点回归系数等方法对长江中游城市群受疫情影响情况进行多尺度综合分析。结果表明：长江中游城市群辐射总值指数在疫情前后呈“匀速增长-显著下跌-快速恢复-小幅回落”4个变化阶段；长江中游城市群灯光变化的空间规律差异明显，鄱阳湖、长株潭和武汉都市圈灯光拟合系数在封锁期间呈“W”和“V”型两种规律，5月灯光恢复程度鄱阳湖>长株潭>武汉都市圈；封锁对武汉市城郊灯光影响效应呈“中心-边缘”衰减规律，其中城区受到冲击较大，回归系数出现断崖式下跌，且恢复时间晚于郊区。
