佳木斯市特殊天气下非甲烷总烃与PM2.5相关性研究
Study on the Correlation between Non-methane Total Hydrocarbons and PM2.5 in Special Weather in Jiamusi City
摘要
Abstract
Under special weather conditions such as air pollution,there is a certain correlation between total non-methane hydrocarbons in ambient air and fine particulate matter PM2.5.Taking Jiamusi City as an example,the variation patterns and correlation between non-methane total hydrocarbons and PM2.5 concentrations under mild and above polluted weather conditions were analyzed.It was concluded that they have different correlations under different weather conditions.In heavily polluted weather,Pearson correlation coefficient and Spearman correlation coefficient were the largest,which are 0.7636 and 0.7400 respectively,indicating that they had a strong positive correlation.While in other weather conditions,the total non-methane hydrocarbons was generally moderately strong positive correlation.Meanwhile,the significant contribution of non-methane total hydrocarbons as precursors to PM2.5 formationfurther was verified.Based on this,suggestions and measures were proposed to provide reference for winning the battle against air pollution.关键词
