摘要
利用山东省济宁市2014—2016年的空气质量监测值和7个环境大气常规监测站点资料,研究和分析了济宁市近3年的空气质量的时间和空间变化特征及其影响因素。结果表明,济宁市采取的大气污染防治措施已取得一定成效,其发生空气污染天数逐年减少,但由于区域传送和气象条件的影响,其发生空气污染的程度有所加重。济宁市整体区域PM10和PM2.5浓度水平基本一致,主要与城市的开发建设、工业排放、交通排放以及大气污染物的区域传送有关。
Based on the data of air quality monitoring system and 7 atmospheric routine monitoring sites in Ji＇ning city from 2014 to2016, the variation characteristics and related influencing factors of air quality in recent three years are analyzed in this paper. The results showed that some achievements have been made because of the preventive measures of air pollution in Ji＇ning, the air pollution days decreased these years, but its degree increased due to regional transport and meteorological conditions. As for PM10 and PM2.5, their amount were both decreased these three years, but the concentrations were still high. there is no obvious difference on the level of PM10 and PM2.5 in Ji＇ning, for the reason of the city＇s development, construction industrial and traffic emissions, and atmospheric pollutants of regional transport.
