南昌市湾里管理局大气污染特征及其防治

Air Pollution Characteristics and Prevention of Nanchang Wanli Administration Bureau

湾里管理局大气环境质量在全市名列前茅,其改善情况同南昌市总体趋势保持一致,同时又体现出一定的差异性。通过对2018—2021年湾里城区大气站点监测的大气环境数据进行分析研究,发现影响湾里空气质量的主要污染物出现由PM2.5逐步向臭氧转变的趋势,湾里臭氧污染高发重点时段内臭氧与PM10存在显著正相关,与湿度存在显著负相关,与气温存在一定正相关。基于此,提出臭氧高发重点时段开展PM10协同管控和人工增雨增湿的建议。

the atmospheric environmental quality of Wanli administration is among the best in the city,and its improvement is consistent with the overall trend of Nanchang,but also reflects some differences.Through the analysis and Research on the atmospheric environment data monitored by the atmospheric station in Wanli urban area from 2018 to 2021,it is found that the main pollutants affecting the air quality in Wanli are caused by PM25.The trend of gradual transformation to ozone.In the key period of high incidence of ozone pollution in Wanli,there is a significant positive correlation between ozone and PM10,a significant negative correlation with humidity and a certain positive correlation with temperature.Based on this,it is proposed to carry out PM10 collaborative control and artificial precipitation and humidification in the key period of high ozone incidence.
