利用武汉市2007-2011年的PM10、SO2、NO2的空气污染指数（API）资料，结合各月气象资料，分析武汉市空气污染物的时空分布特征，并利用灰色关联法分析5个气象因子对空气污染物浓度的影响。结果表明：2007-2011年，武汉空气质量越来越好，主要是首要污染物PM10年均浓度逐渐下降，并于2011年达到国家二级标准，SO2和NO2年均浓度一直低于国家二级标准；各气象因子对PM10的灰色关联度排序依次为降雨量＞相对湿度＞平均风速＞平均气压＞平均温度，各气象因子对SO2的灰色关联度排序依次为降雨量＞平均风速＞相对湿度＞平均温度＞平均气压，各气象因子对NO2的灰色关联度排序依次为降雨量＞相对湿度＞平均风速＞平均温度＞平均气压，意味着降雨量是影响空气污染物浓度的最主要的气象因素，相对湿度和风速次之，气压和温度影响最小。

The spatial and temporal characteristics of Wuhan from 2007 to 201 1 were examined based on the air pollutant index involving PM10 ,SO2 ,and NO2 combining with the monthly meteorological indicators.Grey correla-tion method is applied to explore the impacts of five meteorological indicators on air pollution as well.The results showed that the air quality of Wuhan was getting better and better from 2007 to 201 1 since the annual average con-centration of PM10 was becoming lower and lower.The PM10 could achieve the second grade of national air standard in 2011.However,the annual average concentrations of SO2 and NO2 stayed higher than the second grade of na-tional air standard.The grey correlation order of meteorological factors on PM10 concentration is rainfall >relative humanity >average wind velocity >average atmospheric pressure >average temperature,with rainfall >aver-age wind velocity >relative humanity >average temperature >average atmospheric pressure on SO2 ,and rainfall>relative humanity >average wind velocity >average temperature >average atmospheric pressure on NO2 , which means that rainfall is the primary meteorological factor on air pollutants concentration,following the relative humanity wind velocity,atmospheric pressure,and temperature at the last.
