【摘要】 基于泰州市环境空气颗粒物手工与自动监测比对工作,对2016—2018年比对监测数据进行相关性和偏差分析评价。结果表明:比对期间,PM_2.5手工与自动监测浓度的相对偏差为-35.2%～6.7%,平均相对偏差为-9.3%;PM₁₀手工与自动监测浓度的相对偏差为-30.3%～22.0%,平均相对偏差为-2.9%。结合PM_2.5、PM₁₀负偏差数据统计分析,颗粒物粒径越小,其手工与自动监测浓度相差越大。颗粒物手工与自动监测值在一定范围内有较好的线性关系,PM_2.5和PM₁₀这2项指标手工与自动监测浓度相关系数均达到0.95以上,相关性较好。更多还原

【Abstract】 Based on the manual and automatic monitoring of ambient air particles in taizhou city, the correlation and deviation of 2016-2018 monitoring data was analyzed and evaluated.The results showed that the relative deviation of PM_2.5 between manual and automatic monitoring concentration was-35.2% to 6.7%, and the average relative deviation was-9.3%.The relative deviation of PM₁₀ between manual and automatic monitoring concentration was-30.3% to 22.0%, and the average relative deviation was-2.9%.Combined with the statistical analysis of PM_2.5 and PM₁₀ negative deviation data, the smaller the particle size, the greater the difference between the manual and automatic monitoring concentration.There is a good linear relationship between manual and automatic monitoring values of particles in a certain range.The correlation of PM_2.5 and PM₁₀ which monitored by manual and automatic is good and the correlation cofficients can reached more than 0.95.更多还原
