摘要
为研究辽阳市大气污染物浓度变化特征及污染状况,采用Pearson相关系数法等方法并建立预报方程对辽阳地市污染物浓度变化特征及PM10与气象因子的关系进行分析。结果表明:交通区为辽阳市平均程度上受污染最严重的地区,2月为辽阳市污染最严重的月份;辽阳市的主要污染物为可吸入颗粒物(PM10);PM10质量浓度月变化与气象因子有较高相关性;建立PM10质量浓度预报方程,预报值与实际值变化趋势基本一致。
To study characteristics and condition of in Liaoyang, analyz relationship between PM10 and meteorological fac- tors with the aid The results show： the most contaminated zones is traffic zones and the pollution level in February; the main pollutant is PM10 ; the monthly variation of PM10 mass concentration have higher correlation with meteorological fac- tors ; forecast equation of PM10 mass concentration is established and there is a resemblance between trend of forecast val- ue and actual value.
