摘要
利用吉林省吉林市环境保护监测中心发布的实时大气环境监测数据,对吉林市采暖期间空气质量演变特征进行研究.分析了吉林市大气中可吸入颗粒物PM_(10)、PM_(2.5)、SO_2、NO_2及O_3月均质量浓度变化趋势、演变特征及在不同功能区的变化规律.结果表明:吉林市大气污染物的浓度具有明显的时空演变特征,采暖期污染物浓度主要受冬季燃煤的影响,主要污染物为颗粒物.空气质量依功能区不同差异不明显,工业区的污染状况相对较复杂.
The characteristics of air quality evolution in Jilin City during the heating period are studied by using the real-time atmospheric environmental monitoring data,which is released by Jilin Environmental Protection Monitoring Center.The trend of monthly average mass concentration of articulate matters(PM 10 ),PM2.5 ,SO2,NO2,and O 3,the evolution characteristics,and the changing rules in different functional areas are analyzed.The results show that the concentration of atmospheric pollutants has obvious spatial-temporal evolution characteristics .The pollutants during the heat supply period are mainly affected by the coal-fired heating ,and the major pollutants are particulate matters.The pollution situation in the industrial area is more serious comparing with those in other functional areas.
