摘要
对2009年9月~2010年9月巫山县环境空气自动监测站的监测数据进行统计、分析和评价,结果表明:PM10年均浓度为95.Oμg/m^3;日均浓度呈偏态(左偏)分布;污染程度有明显的季节性变化,冬季〉春季〉秋季〉夏季;春、夏季分别在上午9点和中午12点达到全天最大值,而秋、冬季则出现在晚上19点;风向、风速和相对湿度对PM10浓度均有明显的影响。
According to analysis of the monitoring data from September of 2009 to September 2010, the results showed that annual concentration of PM10 is 95.0μg/M^3 and daily concentration is skew distribution (left skew distribution. Pollution level indicated obvious seasonal changes, the winter had the worse situation of PM10, followed by Spring, next is Autumn, and Summer was the best in a year. The concentration of PM10, which reached daily maximum value at different times in different seasons, was affected evidently by wind direction, wind speed and relative humidity.
