Abstract由于秋冬季节为空气污染高发季节,本研究采用连续自动监测方法于2013年9月-2014年4月对处于四川盆地内的中等城市绵阳市主城区富乐山、市人大、三水厂、高新区四个点进行空气质量监测。监测结果表明:空间分 布上PM10和PM2.5污染程度城西工业区最高,市中心其次,森林公园最低。季节变化PM10和PM2.5污染程度为:春季<秋季<冬季。一天内PM10和PM2.5小时均值呈双峰分布。PM10和PM2.5一元线性回归方程为:y = 0.7273x - 2.9869,回归分析相关性系数0.94。ρ(PM2.5)/ρ(PM10)平均比值为0.7,变化范围为0.27-0.93。
Other AbstractPM10 and PM2. 5 were monitored simultaneously by continuous on-line measurement instruments from September 2013 to April 2014 at Fule Mountain,Municipal people's congress,sanshui factory,high-tech zone in Mianyang urban area. The result showed that PM10 and PM2. 5 pollution level had the order of High-tech zone > Municipal people’s congress > Sanshui factory > Fule Mountain. Seasonal change magnitudes of PM10 and PM2. 5 pollution presented the order of spring < autumn
< winter. The hour average of PM10 and PM2. 5 exhibited two peaks in a day. Correlation analysis of the average daily data gave a linear regression equation: y = 0. 7273x - 2. 9869,with regression analysis correlation coefficient of 0. 94. The average ratio of ρ( PM2. 5 ) /ρ( PM10) was 0. 7,ranging from 0. 27 to 0. 93.
