摘要
分析了空气污染指数(API)系统在评价空气污染水平中的不足,提出了在原API系统基础上进行指标拓展,增加能见度和PM2.5评价指标,建立空气质量综合评价指数(AQI)。分析了扬州市区PM2.5和能见度在雾霾日及正常日的百分位分布,确定了PM2.5和能见度分级值,并利用扬州市区环境空气质量监测数据进行了验证。
The comprehensive index of environmental air quality （AQI） was put forward by appending visibility and PM2.5 comprehensive indexes in the original API system, which has been deficient in the assessment of air pollution level. The ranked value of PM2.5 and visibility was established by analyzing the distribution of PM2.5 and visibility in Yangzhou downtown. The result was verified by ambient air environmental monitoring data of Yangzhou.
