摘要
利用2016—2020年乌海国家一般站气象数据和生态环境局主要大气污染物质量浓度的监测资料。结果表明,乌海市各污染物含量呈现冬高夏低的季节性变化特征,利用后向轨迹模型模拟乌海市5年冬季的后向轨迹,对乌海市污染潜在源区方向进行分析。利用SPSS对污染物之间及污染物与气象要素进行相关性分析,得出污染物含量同气压、温度呈正相关,降水及相对湿度对污染物有冲刷作用。
Based on the meteorological data of Wuhai national general station and the monitoring data of the main air pollutant concentration of the Ecological Environment Bureau from 2016 to 2020. The results show that the pollutant content in Wuhai City is high in winter and low in summer. The backward trajectory model is used to simulate the five-year winter backward trajectory of Wuhai City, and the direction of the potential source of pollution in Wuhai City is analyzed. Using SPSS to analyze the correlation between pollutants and meteorological elements, it is concluded that the content of pollutants is positively correlated with air pressure and temperature, and precipitation and relative humidity have scouring effect on pollutants.
