摘要
目的分析2001—2010年湖北省武汉市空气污染指数(API)的动态特征。方法数据分析基于中华人民共和国环境保护部—政府网站数据中心公布的数据以及武汉市环境保护局发布的API及各污染分指数公报。结果 2001—2010年,武汉市API年均值呈逐年下降趋势,由2001年的101降为2010年的78;可吸入颗粒物的年均值也由2001年的105降为2010年的78;SO2和NO2的API分指数年均值基本保持稳定,可吸入颗粒物是每日首要污染物,其次为SO2,一年中,夏季II级空气质量报告天数最多,冬季最少。结论 2001—2010年,武汉市空气质量总体呈上升趋势;控制可吸入颗粒物和SO2排放量是改善武汉市空气质量的重要环节之一。
Objective To analyze dynamic trend of air pollution index（API） in Wuhan city from 2001 to 2010.Methods Daily API data were collected from the daily report of API in Wuhan city between 2001 to 2010 published by the Ministry of Environment Protection of the People＇s Republic of China and Wuhan Municipal Enviromment Protection Bureau.Results The annual average API in Wuhan city decreased gradually between 2001 to 2010.A decrease in annual average API from 101 in 2001 to 78 in 2010 was observed.The annual average inhalable particulate matter（particulate matter less than 10 μm in aerodynamic diameter） also decreased from 105 in 2001 to 78 in 2010.The annual average sulfur dioxide（SO2） and nitrogen dioxide（NO2） levels were mainly steady.PM10 was one of the principal pollutants in the ambient air of the city,followed by sulfur dioxide.The numbers of days with grade II air quality was the greatest in summer and the least in winter.Conclusion Over the past ten years,air quality in Wuhan city was significantly improved.PM10 and SO2 should be controlled to further improve the quality of ambient air in Wuhan city.
