摘　　要：Airborne microorganisms(AM)have significant environmental and health implications.Extensive studies have been conducted to investigate the factors influencing the composition and diversity of AM.However,the knowledge of AM with anthropogenic activities has not reach a consensus.In this study,we took advantage of the dramatic decline of outdoor anthropogenic activities resulting from COVID-19 lockdown to reveal their associations.We collected airborne particulate matter before and during the lockdown period in two cities.The results showed that it was fungal diversity and communities but not bacteria obviously different between pre-lockdownand lockdown samples,suggesting that airborne fungiwere more susceptible to anthropogenic activities than bacteria.However,after the implementation of lockdown,the co-occurrence networks of both bacterial and fungal community became more complex,whichmight be due to the variation of microbial sources.Furthermore,Mantel test and correlation analysis showed that air pollutants also partly contributed to microbial alterations.Airborne fungal community was more affected by air pollutants than bacterial community.Notably,some human pathogens like Nigrospora and Arthrinium were negatively correlated with air pollutants.Overall,our study highlighted the more impacts of anthropogenic activities on airborne fungal community than bacterial community and advanced the understanding of associations between anthropogenic activities and AM.
