Analysis of Air Quality Over China and Suggestions on Air Quality Daily Report Improvement
-
摘要: 通过对我国空气质量状况分析发现,空气中SO2和PM10等污染物浓度持续下降,灰霾、光化学污染等复合型大气污染问题日益突出,现行的空气质量日报空气污染指数(API)系统表现出其局限性。以2009年天津、上海、重庆、广州和宁波市相关监测点位的空气质量数据为依据,通过3种测算方案评价了在我国现行空气质量日报系统中加入不同监测因子对优良天数的影响,建议增加O3和PM2.5等监测因子。

Abstract: Based on China's air quality condition analysis, it was shown that while the control of SO2 and PM10 had achieved positive progress, complex atmospheric pollution problems such as haze, photochemical pollution had been increased. The existing API system of air quality daily report had shown its limitations. Also, based on the data collected from the monitoring sites in the cities of Tianjin, Shanghai, Chongqing, Guangzhou and Ningbo, the impacts of adding different monitoring factors into the existing air quality daily report system on the fine days were evaluated using three estimation programs. It was thus proposed that monitoring factors such as O3 and PM2.5 should be added to the existing air quality daily report system.-
