摘要
为探究沈阳市供暖期间PM_(2.5)所表现出的污染规律,文章利用环境空气质量监测资料和地面气象要素观测资料分析2021年沈阳市供暖期间PM_(2.5)污染特征,同时分析了PM_(2.5)质量浓度与地面气象要素之间的关系。结果表明:沈阳市供暖期间污染天气现象出现较为频繁;PM_(2.5)月平均质量浓度最高出现在2022年1月,最低出现在2021年11月;沈阳市供暖期PM_(2.5)质量浓度与气压、相对湿度均呈正相关,与温度、风速呈负相关。需要重点关注沈阳市供暖期1月份低温小风等天气现象并加强污染天气治理。
To explore the pollution patterns of PM_(2.5)during the heating period in Shenyang,this article uses environmental air quality monitoring data and ground meteorological element observation data to analyze the pollution characteristics of PM_(2.5)during the heating period in Shenyang in 2021.At the same time,the relationship between PM_(2.5)mass concentration and ground meteorological elements is analyzed.The results show that there are many polluted weather phenomena during the heating period in Shenyang,with the highest monthly average concentration of PM_(2.5)occurring in January 2022 and the lowest in November 2021.The PM_(2.5)mass concentration during the heating period in Shenyang is positively correlated with air pressure,temperature,and relative humidity,while negatively correlated with wind speed.It s necessary to focus on weather phenomena such as low temperatures and light winds during the heating period in January in Shenyang and strengthen pollution control.
