摘要
对兰州市１９８３年以来的几次大规模的大气污染监测试验数据，采用偏度和峰度系数法进行了分布类型检验与统计分析，揭示了８种主要空气污染物浓度的分布类型及其冬、夏两季平均浓度变化特征，找出了它们之间的相互关系．
By using the method of the skew coefficient and peak coefficient, the concentration distribution patterns of air pollutants from several monitoring experiments of ambient pollutions in Lanzhou have been examined. The results reveal that none of the concentrations distribtuion patterns of eight main air pollutants is normal, but SO2 .TSP.CO.O3 and NOx comply with logarithmic normal distribution. At the same time, the average values and interrelations of the eight main air pollutant concentrations in winter and summer are shown by statistical analysis. Among them, the concentration of NMHC is the highest and the positive correlation between SO2 and TSP is the most remarkable.
