摘要
利用2004年至2007年空气污染监测数据,比较现行API指数和修正后API指数的差异,分析修正后O3污染的变化状况,研究O3污染的季节变化。结果表明,O3作为一种新的空气污染指标,对修正后API指数的影响很大。与现行API指数相比,4年来修正后API指数的污染率大幅度增加,并且各季节的污染率越来越接近,2007年污染率在25%左右。2007年各季节修正后API指数污染天数中O3污染天数所占百分比分别是春季为52%、夏季91.6%、秋季20.8%、冬季O3,未出现污染。
Based on the air pollution monitoring datas,the variation was compared with revised API and applicabe API.The results showed that ozone pollutant was major affected air pollution index as one kind of new air pollution index.The frequency of pollution in revised air quality was large quantity increased than applicabe air quality from 2004 to 2007,and the prequency of ozone pollution in 2007 were all about 25% in different seasons,which was nearer and nearer than last 3 years.The percentage of ozone pollution days for 4 parameters air quality each season in 2007 were 52% in Spring,91.6% in Summer,20.8% in Fall,and no appearing pollution of ozone in Winter,respectively.
