【摘要】 气象要素是影响空气质量的重要因子.以德州市为例,选取了近5年德州市春节期间大气污染物浓度及气象数据,采用多种统计方法分析了大气污染物的变化以及气象与大气污染的关系,量化天气形势和局部气象要素对春节期间德州市大气污染物质量浓度变化的贡献.结果表明,PM_2.5,PM₁₀,SO₂,NO₂等4种污染物浓度受温度、湿度和风速等气象要素影响较大,其中PM_2.5和PM₁₀主要受湿度影响,SO₂主要受风速影响,NO₂受湿度和风速影响都相对较大.此研究为德州市在春节期间加强大气污染防治提供一定的数据基础和科学依据.更多还原

【Abstract】 Meteorological elements are important factors affecting air quality.Taking Dezhou City as an example,selects the concentration of atmospheric pollutants and meteorological data during the Spring Festival of Dezhou City in the past five years,and analyzes the changes of atmospheric pollutants and the relationship between meteorological conditions and atmospheric pollutants by using various statistical methods to quantify the weather situation and local meteorology.The contribution of the meteorological elements to the changes in the concentration of atmospheric pollutants in Dezhou during the Spring Festival.The results show that the concentrations of PM_2.5,PM₁₀,SO₂,NO₂ are greatly affected by meteorological elements such as temperrature,humidity and wind speed.PM_2.5 and PM₁₀ are mainly affected by humidity,SO₂ is mainly affected by wind speed,and NO₂ is largely affected by humidity and wind speed.The analysis of can provide a data foundation and scientific basis for strengthening the prevention and control of atmospheric pollutants during the Spring Festival in Dezhou City.更多还原
