摘要:
洛阳是我国工业重地，长期受大气污染困扰。利用2014年1月—2016年12月的PM10，NO2和SO2监测数据，分析了洛阳市不同大气污染物的日均值变化、月均值变化、年均值以及各污染物浓度与气候因素的相关性分析。结果表明：洛阳市空气质量首要污染物为PM10，2014—2016年平均浓度分别为（119.4±64.5）μg/m3，（124.4±68.1）μg/m3和（129.0±91.2）μg/m3，超过国家环境空气质量二级标准；NO2次之，而SO2并未超过国家环境空气质量二级标准。2014—2016年，三种污染物浓度的月变化趋势相同，呈现U型变化；PM10，NO2及SO2三种污染物冬季浓度最大，夏季浓度最低；PM10和NO2年均污染浓度有增加趋势，SO2年均污染浓度逐年下降。各种气象要素与大气污染物的Pearson相关性分析显示，风速、气压、气温、水汽压的影响较为显著，而平均相对湿度的影响相对较弱。大气污染物浓度受到了各种气象因素综合影响。
Abstract:
To understand atmospheric pollution levels and their temporal variation in Luoyang, the concentrations of PM10, SO2 and NO2 in that city were measured continuously by the monitoring equipments from January, 2014 to December, 2016. The results showed that the primary pollutant was PM10, the annual average concentrations were (119.4 ±64.5) μg/m3, (124.4 ±68.1) μg/m3 and (129.0 ±91.2) μg/m3 from 2014 to 2016, respectively. Based on the National Environmental Air Quality Standard of China, all the levels of PM10 during the three years exceeded the secondary grade; sequentially, NO2 was a bit outside the range of the secondary grade, while SO2 was not over the secondary grade. The monthly variations of average concentrations of three pollutants were similar, and their trends appeared U-shape. The three pollutant concentrations were the highest in summer and the lowest in winter. Gradually, annual average concentrations of PM10 and NO2 were both rising while annual average concentration of SO2 was reducing year by year. Pearson analysis indicated that air pollutants were significantly correlated with wind speed, air pressure, air temperature and vapor pressure, and weakly correlated with average relative humidity. It is not a single role that various meteorological factors have the influence on the air pollutant variation, but the combination of those meteorological factors do.
