摘要 根据2007年原国家环境保护总局空气质量日报86个城市的空气污染指数资料,分析我国城市大气污染的时空分布特征。结果表明,我国城市大气污染时空分布特征明显,大气污染冬季最严重,其次为春秋季节,夏季最好;污染总体上北方重于南方。城市大气污染由人类活动及当地特殊的地理位置综合影响形成,沙尘天气加重了北方大气污染。 The temporal-spatial characteristics of air pollution in Chinese cities was analyzed according to 86 cities daily air pollution index information from air daily quality papers issued by the State Environmental Protection Administration in 2007. The results showed that: the temporal-spatial characteristics of air pollution in Chinese cities were obvious, The most serious air pollution in winter, followed by in spring and in autumn, the best in summer; Air pollution in the north cities was more serious than in the south cities. The reason of urban air pollution caused by human activities and effects of special geographical location as well as dust weather in the north cites.
