山东省环境空气“‘蓝天白云、繁星闪烁’标准”解析

Analysis of Shandong Provincial Ambient Air “Blue-Sky-and-Starry-Night”Standard

山东省环保部门提出使用"蓝天白云、繁星闪烁"标准评价空气质量,该标准使用能见度作为主要技术判定指标。为了探讨这种"具象性"标准对空气质量的指示能力,对2013—2014年监测数据进行了深入分析。结果显示,能见度与颗粒物有良好的相关性,与气态污染物的相关性均一般。源于能见度与空气污染物的密切关系,"蓝天白云、繁星闪烁"标准能够将空气污染物水平大致划分为优劣两类,但对各种污染物的指示能力不同。

The ＂blue-sky-and-starry-night＂standard was set to assess air quality by Shandong provincial environmental protection departments,and the standard uses visibility as the main technical indicator. In order to investigate the capability of the figurative standard to indicate air quality,deep analysis is conducted using the monitoring data during 2013—2014. The results show that air visibility has a good correlation with particulate matter and is moderately correlated with gaseous pollutants. Based on the close relationship between visibility and air pollutants,the＂blue-sky-and-starry-night＂standard can roughly divide air pollutant levels into two categories： good and unhealthy,but it has different indicating capabilities for various pollutants.
