 摘要:随着北京雾霾天气的频繁发生,空气质量状况日益受到关注。运用时间序列分析描述方法,描述2001—2012年间北京市的空气污染指数(air pollution index,API)随时间的变化趋势及与降雨量、风速、气温、湿度等气象因素的相关性。结果表明API指数整体呈下降趋势;春季和冬季的月API指数最高,夏季最低,存在明显的季节性,3、4月的月API指数较高,7、8月的月API指数最低;首要污染物中SO2所占的比例在减少,可吸入颗粒物的比例在升高;API指数与降雨量存在负相关关系,与风速、气温、湿度等存在正相关的关系。

 Abstract: As the haze occurred frequently in Beijing, more and more attentions have been paid to air quality.  A time series analysis method was used to describe the trend of Air Pollution Index (API) in Beijing in 2001—2012, and to find out the correlation of API with precipitation, wind speed, temperature and humidity. Results There was a declining trend for API index in general, and a significant seasonal variation of API, which was the highest in the spring and winter, and the lowest in the summer; The API was higher in March and April, and lower in July and August. Among the primary pollutants, the proportion of SO2 reduced as the proportion of inhalable particulate matter increased; the API index was negatively correlated with precipitation, and positively correlated with wind speed, temperature and humidity.
