平原城市大气污染物浓度变化及相关性分析

Analysis on Concentration and Correlation Change of Atmospheric Pollutants in Plain City

通过对伏牛山余脉东侧中部平原城市大气污染物浓度监测数据分析发现,大气污染具有地域性特征,主要污染物浓度均呈现显著的相关性.以许昌市作为研究对象,对其2015年PM_(2.5)、PM_(10)、SO_2、NO_2及O_3等主要大气污染物浓度变化趋势和季节性分布进行分析对比.通过CORREL相关性模型分析,对各污染因子间的相关性进行研究,得到各污染物浓度的地域性变化和相关性结果,为制定本市大气防治和参与区域协同管控提供决策支持.

Analyzing the atmospheric pollutants＇ concentration monitoring data of the cities in the east slope of central plains of Funiu Mountain odd arteries,we can find that air pollution in this area has its regional characteristic,of which the main pollutants concentrations are presented to be of significant correlation. Taking Xuchang City as an example,This article compares the data of main atmospheric pollutants＇ concentration in2015 with their change trend and seasonal distribution including PM2. 5,PM10,SO2,NO2,O3 and others. Analyzing the correlation among these pollution factors by CORREL correlation model,we finally find the regional changes of each pollutant＇s concentration and correlation results,which can provide decision-making support for the city＇s air pollution control and regional coordination control.
