为了解天津滨海新区塘沽供暖期前后大气污染物浓度水平的变化特征，利用2013年10月1日～12月29日NO2、SO2、PM2.5、PM10的连续在线监测数据，以供暖前10月1日～11月14日及供暖期11月15日～12月29日2个时间段来分析各污染物的变化特征。结果表明，滨海新区塘沽供暖期比供暖前PM10、PM2.5、NO2及SO2的日均浓度分别上升了46.7%、8.9%、60.5%和117.9%；4种大气污染物的日均浓度最高值均出现在供暖期；供暖期PM10、PM2.5、NO2及 SO2的日均超标平均倍数较供暖前均有所上升；供暖期 PM10、NO2及 SO2的超标率均比供暖前上升，而PM2.5的超标率则下降。

In order to understand the variation characteristics of atmospheric pollutant concentration level in Tanggu, Tianjin Binhai New Area pre and amid the heating period,the continuous on-line monitoring data of NO2,SO2, PM2.5 and PM10 from October 1st to December 29th in 2013 were used to analyze the variation characteristics of various pollutants before the heating period,from October 1st to November 14th,and during the heating period, from November 15th to December 29th. The results showed that,average concentrations of PM10,PM2.5,NO2 and SO2 during the heating period increased by 46.7%,8.9%,60.5% and 117.9% compared with those before the period in Tanggu;all peak values of daily average concentration of the four air pollutants emerged in the heating pe-riod;daily average exceeding rates of PM10,PM2.5,NO2 and SO2 increased during the period;and over standard rates of PM10,NO2 and SO2 ascended while the rate of PM2.5 descended.
