    摘要: 收集了太原市环境监测中心站公布的PM2.5和PM10逐时监测数据,分析了PM2.5和PM10的月、日及小时浓度分布特征和变化规律,结果表明:2013年夏季太原市PM10的日浓度范围为32~276 μg/m3,PM2.5的日浓度范围为17~136 μg/m3,PM2.5和PM10的日均值的最大值均出现在六月份,PM2.5和PM10日变化规律一致,呈单谷趋势,PM2.5与PM10比值在0.46~0.55之间,二者相关性显著,相关系数为0.81。Real-time data of PM2.5 and PM10 concentrations in summer of 2013 released from Taiyuan Environmental Monitoring Center were collected. The regular pattern of their distribution and temporal (monthly, daily and hourly) va- riations were analyzed. The results showed that daily concentrations of PM10 ranged between 32 - 276 μg/m3 and those of PM2.5 ranged between 17 - 136 μg/m3. Similar diurnal variations of PM2.5 and PM10 concentrations with single-valley pattern were observed. Daily maximum concentrations of both PM2.5 and PM10 appeared in June. PM2.5/PM10 ratios varied between 0.46 - 0.55, and significant linear correlation (correlation coefficient of 0.81) between PM2.5 and PM10 was found.
