银川市初夏气溶胶粒子谱分布特征

Characteristics of Aerosol Particle Size Distribution during Summer in Yinchuan City, Ningxi Province

利用美制APS 3310A型激光粒谱仪,在中国西北城市银川对大气气溶胶粒子进行现场观测,结合气象条件,并通过理论计算分析,给出了银川市初夏大气气溶胶的日变化特征、3种不同粒径粒子分布特点及飘尘谱分布特征,以期为银川市大气污染总量控制方案及对策提供科学依据。

Atmospheric Aerosol Particle (AP) in situ observations have been carried out in three areas of urban and suburb of Yinchuan city, Ningxi provinces by mean of APS\|3310A instrument made in USA. Data and the calculating results have showed the characteristics of AP diurnal variation, size distribution of three various particles and floating dusts. It can provide references to air pollutants controlling scheme and strategy of Yinchuan city, Ningxi province.
