摘    要:通过对兰州市城关区2000年春季大气气溶胶的监测,分析了该地区总悬浮颗粒物(TSP)的质量浓度及飘尘的粒径分布规律,结果表明:春季该地区TSP及飘尘的污染十分严重,TSP的质量浓度的日变化为双峰型;粗粒子在飘尘中的比例比较大;气象条件,人为活动规律对TSP的质量浓度变化规律及飘尘的粒径分布规律影响较大。

关 键 词:兰州市  城关区  2000年  春季  大气气溶胶  空气质量监测

Abstract:Through monitoring of the aerosols in Chengguan District of Lanzhou City in the spring of 2000,the total suspended particulates (TSP) mass concentration and particle size distribution were analyzed.The results indicated that the district is much polluted by TSP and floating dust in the spring;the daily variation of TSP mass concentration presents a curve of two peaks;the percentage of fine particles in the floating dust is high;and meteorological conditions and regularity of human activities have great effects on the mass concentration of TSP.
Keywords:TSP  floating dust  mass concentration  meteorological condition  regularity of human activities
