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PM_(10),NO_2和SO_2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PM_(10),2014—2016年平均浓度分别为(119.4±64.5)μg/m~3,(124.4±68.1)μg/m~3和(129.0±91.2)μg/m~3,超过国家环境空气质量二级标准;NO_2次之,而SO_2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;PM_(10),NO_2及SO_2三种污染物冬季浓度最大,夏季浓度最低;PM_(10)和NO_2年均污染浓度有增加趋势,SO_2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。

摘  要：
To understand atmospheric pollution levels and their temporal variation in Luoyang,the concentrations of PM_(10),SO_2 and NO_2 in that city were measured continuously by the monitoring equipments from January,2014 to December,2016.The results showed that the primary pollutant was PM_(10),the annual average concentrations were(119.4 ± 64.5)μg/m~3,(124.4 ± 68.1)μg/m~3 and(129.0 ± 91.2)μg/m~3 from 2014 to 2016,respectively.Based on the National Environmental Air Quality Standard of China,all the levels of PM_(10) during the three years exceeded the secondary grade;sequentially,NO_2 was a bit outside the range of the secondary grade,while SO_2 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 PM_(10) and NO_2 were both rising while annual average concentration of SO_2 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.
