摘　　要：为研究宁波市大气污染状况及其影响因素,利用2013—2018年宁波市国控站点实时监测污染物数据以及气象数据,探讨分析了宁波市大气污染特征以及所受气象因素的影响概况。结果表明:宁波市颗粒物污染和O3污染呈现典型的季节性特征,颗粒物浓度冬季最高,O3最大滑动8 h平均质量浓度春、秋季最高。宁波市O3污染问题越来越突出,且呈现出春、秋季O3超标天数最多的季节变化特征。O3小时质量浓度与气温和太阳辐射成正相关关系,NO2和颗粒物浓度与气温成负相关关系。NO2与O3浓度成负相关关系,与颗粒物浓度成正相关关系。To study the general condition and influence factors of air pollution in Ningbo City,the article analyzed the characteristics and the survey of the influence of meteorological factors by using the real-time monitoring pollutant data and meteorological data of Ningbo city from 2013 to 2018.The results show:Particulate matter pollution and ozone pollution show the typical seasonal characteristics that particulate matter pollution occurs easily in winter and ozone pollution occurs easily in spring and autumn.The ozone pollution is becoming more and more prominent,and shows the seasonal variation characteristics that are obvious in spring and autumn in Ningbo.Ozone concentration is positively correlated with temperature and solar radiation.NO2 and particulate matter are negatively correlated with temperature.NO2 is a negative correlation with O3,and a positive correlation with particulate matter.
