北京市大气环境二氧化硫浓度分布初探
- STATISTICAL DISYRIBRYION OF SULPHR DIOXIDE CONCENTRATIONS IN THE AREA OF BEIJIING
- 摘要:利用北京市大气自动监测系统冬季逐时二氧化硫浓度监测资料,分析研究了对数正态分布、Weibull分布、指数分布等常用分布模型对监测资料分布拟合的适用性,并估算出各种分布模型的参数值。研究发现城区及高百分位数二氧化硫浓度频率分布符合Weibull分布,近郊及背景站的浓度分布符合常用的对数正态分布,二氧化硫浓度的频率分布不符合指教分布规律。
- Abstract:This paper describes three distributional models,applied to winter hour-ly sulphur dioxide concentrations data from the Automated Air Pollution Monitoring System of Beijing.It was found that(a) Weibull distribution is the best for highly sulphur dioxide data,(b) lognormal distribution is ap propriate for the majority of sulphur dioxide data,(c)exponential distribu-tion is not appropriate for urban sulphur dioxide concentration data.
