Due to the COVID-19 outbreak, Wuhan was locked down from 23 January 2020 to 8 April 2020, a total of 76 days. It is well known that the electricity consumption is a direct reflection of human activity. During the lockdown of Wuhan, most of human activities were forbidden. The reduction in human activity would inevitably lead to a reduction in electricity consumption. At the same time, anthropogenic emissions of air pollutants would also be reduced with the reduction of human activity. In this study, the correlation between electricity consumption and air pollutants during lockdown was discussed in detail. The result showed that the drop in pollutants concentrations in January should be attributed to the washout effect of rainfall rather than the lockdown. The decrease of electricity consumption in the secondary industry might play a significant role on the decrease of PM${}_{\mathrm{2.5}}$ and NO₂ concentrations in Wuhan in February 2020. The decrease in NO₂ concentration in March should be attributed to the reduction of pollutants emissions from the tertiary industry, which means that more attention should be paid to the control of NO₂ emission in the tertiary industry. Due to reduced emissions from local sources, the role of long-range transport sources might be more significant during the lockdown of Wuhan. By PSCF analysis, southeast of Wuhan could be the major potential emission sources of PM${}_{\mathrm{2.5}}$, especially in the northern part of Jiangxi province. It was suggested that stricter regulation of pollutants emissions should be implemented in this area.

由于COVID-19爆发，武汉从2020年1月23日至2020年4月8日封城，共计76天。众所周知，电力消耗是人类活动的直接反映。武汉封城期间，人类大部分活动都被禁止。人类活动的减少将不可避免地导致电力消耗的减少。同时，随着人类活动的减少，人为排放的空气污染物也会减少。在这项研究中，详细讨论了封锁期间电力消耗与空气污染物之间的相关性。结果显示，1月份污染物浓度下降应归因于降雨的冲刷作用，而不是封城。第二产业用电量下降可能对PM2.5下降起到显着作用2020年2月武汉市NO ₂浓度。3月份NO ₂浓度下降应归因于第三产业污染物排放的减少，这意味着应更加重视第三产业NO ₂排放的控制行业。由于本地源排放减少，在武汉封城期间，远程运输源的作用可能更加重要。 PSCF分析，武汉东南部可能是PM主要潜在排放源尤其是江西北部地区。 建议对该领域实施更严格的污染物排放监管。
