六盘水市空气质量标况数据转实况数据后的差异性分析

Analysis of the Difference Between Liupanshui Air Quality Standard Data and Real-time Data

六盘水市空气质量标况浓度转换实况浓度后,PM_(10)、PM_(2.5)年均浓度降低20%以上,SO_(2)、NO_(2)、CO-95per、O_(3)降低约10%;空气质量综合指数降低0.43-0.58;十三五末期与初期采用不同状态浓度对比,PM_(10)、PM_(2.5)及CO-95per削减量差距达到13%、16%、7%,O_(3)-8h90per百分位增加量差距为12%。虽然在日常工作中采用实况浓度计算时符合当地空气质量实际情况,但在计算污染物削减情况及污染治理成效时,应考虑采用相同标准下的数据进行对比才能符合真实变化情况。

After the conversion of standard concentration of air quality in Liupanshui City,PM_(10)、PM_(2.5) The average annual concentration is reduced by more than 20%,and SO_(2),NO_(2),CO and O_(3) are reduced by about 10%;The comprehensive air quality index decreased by 0.43~0.58;At the end of the 13th Five Year Plan period,PM_(10),PM_(2.5) and CO-95per reduction gap reached 13%,16%and 7%,and O_(3)-8h90per percentile increase gap was 12%.Although the actual concentration calculation in daily work is in line with the actual situation of local air quality,when calculating the pollutant reduction and pollution control effect,it should be considered to compare the data under the same standard in order to meet the real change.
