摘要
通过分析徐州市近几年的大气PM10监测数据和气象条件,研究了大气PM10质量浓度的时间变化规律及气象因素的影响,结果表明:PM10质量浓度年变化呈"冬重夏轻"的规律;在大气污染源数量和污染物排放量相对稳定的情况下,风和降水是影响大气颗粒物污染程度的主要气象因子,PM10浓度随温度的升高而降低,随气压的增强而减少。
This paper studied the temporal change of the PM10 concentration and the effects of meteorological factors on the PM10 concentration by means of analyzing Xuzhou city＇s PM10 monitoring data and meteorological factors in recent years. The results show that the PM10 concentration during the winter is higher than that during the summer; for different spatial scales, when the number of air pollution source and the amount of emitted pollutant are stable, wind and precipitation are the main meteorological factors controlling the atmospheric particulate matter pollution; PM10 concentration decreases with the increase of temperature and atmospheric pressure.
