摘要: 为了解辽阳市PM10的时空分布特征,掌握PM10的变化规律,为辽阳市空气污染预报及防控提供科学依据,本文利用2006-2012年辽阳市逐日PM10监测资料对辽阳市PM10的时空变化特征进行了分析。结果表明:2006-2012年辽阳市首要污染物为PM10,PM10年平均浓度呈显著下降的趋势;冬季PM10浓度最大,其次为春季和秋季,夏季PM10浓度最小;PM10月平均浓度变化呈“U”型分布,1月、2月和12月PM10浓度较高,7月PM10浓度最低。空间分布上,PM10浓度最高的为园林小区监测点(居民区),其次为钢管厂(工业区)和201血站(交通区)监测点,辽化监测点(清洁区)PM10浓度最低;近7 a钢管厂监测点PM10浓度呈略升高的趋势,其他3个监测点PM10浓度均呈下降的趋势。

Abstract: In order to understand the spatiotemporal distribution of PM10 over Liaoyang of Liaoning province and provide a scientific basis for air pollution prediction and measure of prevention,the spatiotemporal variations of PM10 were analyzed using daily monitoring data of PM10 in Liaoyang of Liaoning province from 2006 to 2012.The results show that the annual mean PM10 concentration decreases significantly during this period.The PM10 concentration is the largest in winter,followed in spring,autumn,and summer.The monthly mean PM10 concentration exhibits a "U" type distribution,with the higher values in January,February and December and the lowest one in July.The highest PM10 concentration is observed in Yuanlinqu station (a residential area),followed by Gangguanchang station (an industrial area),201 Xuezhan station (a traffic area),and Liaohua station(a clean area).The PM10 concentration has been observed decreasing at all monitoring stations in the recent 7 years,except for the Gangguanchang station.
