哈尔滨市燃煤期PM_(10)和PM_(2.5)比对测试研究

Comparative Analysis on PM_(10) and PM_(2.5) ratio during Heating Period in Harbin

哈尔滨市的地域性决定了气候非常具有代表性。以冬季特为明显,气温早晚温差大,气温低。再加上正是采暖期间,空气质量受供暖期等影响较大,空气质量不稳定。2013年冬季选择哈尔滨市燃煤期PM10和PM2.5比对测试研究分析,对市区内3个监测点位进行的颗粒物(PM10和PM2.5)手工采样与自动仪器的比对监测,以手工监测方法为基准,分析自动监测与手工监测的一致性,并对PM10和PM2.5浓度的比值关系进行了分析,结果表明:监测3个点位的PM10和PM2.5的浓度趋势具有很高的一致性,且以手工和自动数据进行线性回归的各项参数均符合技术规范(HJ 653-2013)的要求。

The geographic location of Harbin decided that the city has distinct seasonal weathers. In winter,the temperature difference in day and night is huge. Moreover,winter is also the heating period,air quality is affected by heating period greatly,resulting in stable air quality. This study adopted PM10 and PM2.5 data from three monitoring stations in the winter of 2013 as example. The data was collected both manually and with monitoring instruments. Consistency analysis of automatic monitoring and manual monitoring data of PM10 and PM2.5 concentration ratio are analyzed. The results show that the concentration of monitoring data from the 3 point have high consistency. The parameters concluded from manual and automatic data by linear regression are in accord with the technical specification（HJ 653-2013） requirements.
