[Spatiotemporal dynamics of atmospheric PM and PM and its influencing factors in Nanchang, China].

PM and PM have become the primary pollutants of most cities in China. Atmospheric PM and PM mass concentrations, meteorological factors, traffic flow from 2013 to 2015 in Nanchang were analyzed. Spatiotemporal dynamic pattern of atmospheric particulate matter pollution and the effect of weather and traffic on particle concentration change were discussed in this paper.
