摘要
本文以2016年太原市8个环境空气自动点位的PM_(2.5)监测数据为基础,分析了太原市PM_(2.5)浓度的时空分布状况。结果表明:PM_(2.5)浓度有明显的时间分布特征,日变化趋势呈双峰型;就季节而言,冬季>秋季>春季>夏季,PM_(2.5)最高值基本都出现在采暖期,月均浓度最大的是12月,达150μg/m3,最小值是8月份,为31μg/m3;空间分布上金胜>小店>晋源>桃园>尖草坪>南寨>坞城>上兰。
In this paper,data of PM2.5 monitoring from 8 automatic air quality monitoring stations of Taiyuan in 2016 were analyzed to temporal and spatial distribution. The results show that the PM2.5 has characteristics of obvious time distribution,and the trend of diurnal variation is bimodal; in terms of the seasons,winterautumnspringsummer,the peak of PM2.5 is basically in the heating period,the maximum monthly concentration is in December,which is 150μg/m^3,the minimum is August,31μg/m^3; in spatial distribution,JinshengXiaodian Jinyuan TaoyuanJiancaopingNanzhaiWuchengShanglan.
