摘　　要：为了更好的治理大气污染,防止持续性大雾天气对生态系统的光合作用、植物呼吸、植物病害、生物多样性和飞行动物等方面产生负面的影响。提出持续性大雾天气成因以及大雾污染程度变化研究。选取江苏省作为研究区域,将江苏省2020年1月12日-15日出现的持续性大雾天气作为研究背景,分析了江苏省各市能见度变化情况,以及空气质量指数、PM2.5和PM10的变化情况。研究了气象因素(温度、湿度和风速)对持续性大雾天气形成产生的影响,同时分析了不同站点处空气污染物的浓度变化情况,结合相关性分析获取上述污染物与气象因素与雾时数和霾时数的相关性。In order to better control air pollution and prevent the negative impact of continuous heavy fog weather on ecosystem photosynthesis,plant respiration,plant diseases,biodiversity,and flying animals,this paper analyzed the causes of persistent heavy fog weather and changes in the degree of heavy fog pollution.Selecting Jiangsu Province as the research area,the continuous heavy fog weather that occurred from January 12 to 15,2020 in Jiangsu Province was used as the research background.The visibility changes in various cities in Jiangsu Province,as well as the changes in air quality index,PM 2.5,and PM 10,were analyzed.The impact of meteorological factors(temperature,humidity,and wind speed)on the formation of persistent heavy fog weather were discussed to analyze the concentration changes of air pollutants at different stations.The correlation between the above pollutants and meteorological factors with fog and haze hours was obtained by combining correlation analysis.
