我国臭氧污染控制分区及其控制类型识别

基于卫星遥感指示剂法，以2017~2019年为基准年份，通过对比臭氧在线监测数据、VOCs和氮氧化物排放强度数据以及卫星遥感数据，在PM_2.5重点监管区域的基础上，重新修订大气污染臭氧重点管控区，将我国臭氧年均浓度超标区（高于160μg/m³）划分为不同重点区域，识别每一个重点区域臭氧前体物敏感类型，即VOCs控制区、NO_x控制区以及VOCs和NO_x协同控制区，针对每种类型进一步细化为本地污染控制区和联防联控控制区，这种结合地面监测、统计调查数据和遥感观测数据的臭氧分区分类方法可以为大气污染的宏观分区分类管控提供一种新的思路，为国家出台全国层面臭氧污染防治及PM_2.5和O₃协同控制相关政策提供决策参考.

Identification of ozone pollution control zones and types in China

This study is based on the satellite remote sensing indicator method, using 2017~2019 as the base years, by comparing ozone on-site monitoring data, VOCs and nitrogen oxide emission intensity data, and satellite remote sensing data, on the basis of PM_2.5 key regulatory areas, reclassifying ozone control areas, which means classifying areas where the annual average concentration of ozone exceeds the standard (above 160μg/m³) into different key zones. Identify the sensitive types of ozone precursors in each key zone, namely VOCs control zone, NO_x control zone, and VOCs and NO_x coordinated control zone; For each type it is further confirmed into local pollution control zones and joint prevention and control zones. This type of ozone classification method that combines ground monitoring data, statistical data and remote sensing observation data can provide a new idea for the macro-zone classification control of air pollution and also provide decision-making reference for the national level of ozone pollution prevention and control, and PM_2.5 & O₃ coordinated control related policies.
