摘要
为了实施更科学更具有针对性的精准防控,对2020年临沂市PM_(2.5)时空排放规律及气象因素的影响进行分析,结果表明PM_(2.5)月浓度高值主要集中在11月-2月,日浓度高值主要集中在上午8时-9时。受主导产业影响,1月PM_(2.5)污染高值分布在兰陵县西部、费县西北部和平邑县东部;12月高值主要分布在兰陵县、高新区和莒南县。秋冬季、湿度60%~90%、盛行西南风和西风时,易出现PM_(2.5)浓度高值。PM_(2.5)污染来源以临沂市排放和苏皖鲁豫区域近距离性污染传输为主。
To implement more scientific and targeted prevention and control,the temporal and spatial variation characteristics of PM_(2.5) and the influence of meteorological factors in Linyi City in 2020 was carried out.The results show that the monthly high concentration of PM_(2.5) was mainly concentrated in November to February,and the daily high concentration is mainly concentrated in 8:00~9:00 a.m.Influenced by leading industries,the high value of PM_(2.5) pollution was distributed in the west of Lanling County,the northwest of Fei County and the east of Pingyi County in January.In December,the high value was mainly distributed in Lanling County,high tech Zone and Junan county.In autumn and winter,when the humidity is 60%~90%,southwest wind and westerly wind prevail,PM_(2.5) concentration is high.The main pollution sources of PM_(2.5) are local emission and short distance pollution transmission in Jiangsu,Anhui,Shandong,and Henan provinces.
