摘　　要：基于2014-2020年长时间序列NPP-VIIRS夜光遥感数据,利用夜间灯光总强度、平均相对灯光强度、灯光面积比和综合灯光指数四种灯光指数,对新冠疫情期间湖北省13个地级行政区的经济活动进行了分析。首先,将灯光指数与湖北省经济指数GDP进行相关性分析,并考虑新冠疫情影响,构建了湖北省经济指数的最佳线性回归模型。其次,基于疫情前后夜间灯光强度的回归坡度,对疫情期间湖北省经济走势进行了分析。最终,形成如下重要结论:1)新冠肺炎疫情的出现导致夜间灯光数据出现断点现象,新冠疫情前后的回归模型及夜间灯光强度存在较大差异;2)夜间灯光指数与社会经济指数呈现显著的线性相关性,可用于较好评估城市级经济指标;3)灯光回归坡度可以较好反映短期经济走势,新冠疫情高峰期间,灯光回归坡度最低为0.81,随着疫情解封,灯光回归坡度逐渐增大,在2020年12月灯光回归坡度回升至1.01,回升至疫情前正常水平。This paper analyzes the economic activities of 13 prefecture-level administrative regions in Hubei Province during the COVID-19 based on the long time series NPP VIIRS night light remote sensing data from 2014 to 2020 using four lighting indices:total night light intensity,average relative light intensity,light area ratio and comprehensive lighting index.Firstly,the correlation analysis between the lighting indices and the economic index GDP of Hubei province was carried out,and the best linear regression model for the economic index of Hubei province was constructed by considering the impact of the COVID-19.Secondly,the economic trend of Hubei province during the epidemic was analyzed based on the regression slope of nighttime light intensity before and after the epidemic.Finally,the following important conclusions were drawn:(1)the emergence of the epidemic led to a breakpoint phenomenon in the nighttime lighting data,and there were large differences in the regression models and nighttime lighting intensity before and after the epidemic;(2)the nighttime lighting index showed significant linear correlation with the socioeconomic index,which can be used to better assess city-level economic indicators;(3)the slope of the lighting regression can better reflect the short-term economic trend,and during the peak of the epidemic the light regression slope was as low as 0.81;and with the lifting of the epidemic,the light regression slope gradually increased;in December 2020 the light regression slope rose back to 1.01.It was back to the normal level before the epidemic.
