| 目的 评价济宁市2014-2017年空气质量现状及主要污染物的变化趋势，为评估本地区大气污染治理效果，进一步提出治理措施提供依据。方法 通过中华人民共和国环境保护部环境空气质量实时发布系统收集济宁市2014年1月1日至2017年12月31日PM2.5、PM10、SO2、NO2及CO的24h平均浓度，O3日最大8h平均浓度及空气质量指数（AQI）。结果 济宁市2014-2017年AQI分布以良（665d，45.5%）和轻度污染（495d，33.9%）为主；冬季的首要污染物为PM2.5，主要分布在1~3月和11~12月，以1月和12月最高；夏季的首要污染物为O3，主要分布在4~10月，以6月份最高；PM2.5、PM10、SO2和NO2的年平均浓度呈现逐年下降趋势，年降低率分别为13.5%、10.0%、28.2%和4.2%；2015-2017年，CO年降低率为9.6%；O3在2014-2016年呈现下降趋势，但2017年较上一年升高14.8%；济宁市主要大气污染物均呈现明显的季节分布特点，PM2.5、PM10、SO2、NO2、CO冬季浓度较高，夏季较低；O3冬季浓度低，夏季浓度较高。结论 近年来济宁市大气污染治理取得一定成效，仍应加强冬季对PM2.5和夏季对O3的控制。 |

| Objective To evaluate the status of air quality and the variation trend of main air pollutants of Jining from 2014 to 2017,and assess the regional air pollution control to provide basis for further treatment measurements.Methods The 24-hour average concentration of PM2.5,PM10,SO2,NO2,CO,maximum 8-hour daily average concentration of O3 and air quality index (AQI) of Jining were collected from the real-time release system of environmental air quality issued by the Ministry of Environmental Protection of China from January 1,2014 to December 31,2017.Results The AQI for most days in Jining were good (665 days,45.5%) and light pollution (495 days,33.9%).PM2.5 was the primary pollutant in winter which mainly distributed in January-March and November-December,with the highest concentration in January and December.In summer from April to October,O3 was the primary pollutant and highest in June.The average annual concentration of PM2.5,PM10,SO2,and NO2 declined steadily by 13.5%,10.0%,28.2%,and 4.2% yearly,and that of CO declined by 9.6% yearly from 2015 to 2017.Though the annual concentration of O3 with a downward trend from 2014 to 2016,it increased by 14.8% in 2017.From 2014 to 2017,the main air pollutants showed apparent seasonal variation in Jining,with the concentration of PM2.5,PM10,SO2,NO2,and CO highest in winter and lowest in summer,and O3 lowest in winter and highest in summer.Conclusion The treatments for air pollution control in Jining has achieved some results.More efforts should be done to decline the PM2.5 in winter and O3 in summer. |
