摘要
:为摸清石家庄市大气污染现状及特征,对石家庄市2002—2011年的空气质量自动监测数
据进行分析。研究结果表明,石家庄的空气质量总体呈好转趋势,优良天数逐年增长,大气中3项
主要污染物浓度连续2年均达到国家二级标准,PM10,SO2 年均浓度呈显著下降,NO2 年均浓度则
呈上升趋势。污染物日变化各季节大致相同,其时空分布不均匀,SO2 与 PM10夏季浓度较低,春冬
季较高,表现出明显的季节性特征;NO2 季节性特征不显著。

Abstract:Air quality data of Shijiazhuang City from 2002to 2011is analyzed to find out the air pollution situation and charac-
results show that,Shijiazhuang's air quality is integrally of fairly good air quality grows year by
year,the concentrations of three main pollutants meets in atmosphere the national secondary standard for consecutively two
years,and the annual average concentrations of PM10 and SO2 decrease,while that of diurnal variation of
each pollutant in each season is roughly the same,but its spatial and temporal di
