摘要
Abstract
Tiexi district of Shenyang city is a traditional heavy industry base with dense industrial enterprises,large traffic flow,and prominent atmospheric particulate matter pollution problems.Taking Tiexi district of Shenyang city as the research area,the spatiotemporal distribution characteristics of regional atmospheric particulate matter concentration are analyzed from 2022 to 2023,in order to strengthen air pollution prevention and control and achieve fine control of atmospheric particulate matter.The results show that the annual average concentrations of inhalable particulate matter(PM10)from 2022 to 2023 are 60 μg/m3 and 58 μg/m3,respectively,meeting the secondary standard;the annual average concentration of fine particulate matter(PM2.5)has decreased from 37 μg/m3 to 35 μg/m3.The time distribution shows significant seasonal changes,and the spatial distribution exhibits a gradient characteristic of decreasing from industrial areas to residential areas.Research has shown that atmospheric particulate pollution in Tiexi district,Shenyang city is generally decreasing,but industrial and transportation sources remain the main sources of atmospheric particulate matter.In the future,it is necessary to strengthen industrial pollution control,optimize transportation structure,and continue to promote air pollution prevention and control.关键词
