摘要
以2001年2月1日至2009年1月31日的空气质量公报为研究对象,分析了21世纪以来上海市SO2污染指数的频率分布特征。结果表明:2001—2008年上海空气质量总体情况良好,夏秋季优于冬季。从SO2污染的影响因素分析结果显示:上海第二产业比重与SO2污染正相关,工业排放是SO2污染的主要产生源。同时,气象条件特别是相对湿度较大与冬季的热岛效应不利于缓解上海SO2污染。
Using the air quality reports from February 1st, 2001 to January 31st, 2009 as object of study, the frequency distribution feature of API （SO2） in Shanghai since the 21st century was analyzed. The results showed that the air quality in Shanghai was fairly good in general from 2001 to 2008, with a better situation in summer and autumn. From analyzing influencing factors of SO2 pollution, there exists a positive relation between the percentage of the secondary industry in Shanghai and sulfur dioxide pollution, indicating that industrial emissions are the main SO2 pollution sources. Meanwhile, meteorological condition, especially large relative humidity and heat island effect in winter, may intensify sulfur dioxide pollution.
