摘      要：The characteristics of the bacterial community structure in aerosols of different particle sizes over northern Chinese marginal seas and the northwestern Pacific Ocean in autumn were analyzed using high-throughput sequencing and the quantitative real-time PCR method based on 16S rRNA *** with environmental factors and air mass sources,the bacterial abundance,community diversity,composition and structural characteristics in aerosols were studied,which might provide a scientific evaluation for a comprehensive understanding of the characteristics,long-distance transmission and ecological effects of aerosols from coastal waters to the distant ocean(northwestern Pacific Ocean).At the junction of the South Yellow Sea and the East China Sea,the bacterial abundance in the aerosols was substantially affected by transmission of continental air masses and was higher than those in other samples,and the bacterial abundance in coarse particle(2.1μm)samples was significantly higher than that in fine particle(0.05).Among the environmental factors examined,a significant negative correlation was observed between bacterial community richness and temperature(P0.05),and the bacterial community diversity was significantly positively correlated with the concentration of K^(+)(P0.05).Canonical correspondence analysis showed that temperature,NH_(4)^(+) concentration and SO_(4)^(2−) concentration exerted significant effects on bacterial community struc
