摘要
根据湖北省武汉市大气主要污染物的浓度数据、空气质量指数，运用线性回归分析、主成分分析法对其大气污染特征进行系统分析。结果表明，PM2．5对空气质量的贡献率最大，为武汉市大气的首要污染物，其浓度季节变化为冬季﹥春季﹥秋季﹥夏季。最后针对武汉市大气污染特征提出防治措施，旨在为改善空气质量提供科学依据。
Abstract
According to concentration data of the pollutants and air quality index , we analysed the atmospheric pollution characteristics in Wuhan City by using linear regression analysis and principal component analysis.The results showed that PM2.5 of the largest contribution rate was the primary atmosphere pollutant, its seasonal variation in concentration was in the order of winter >spring >autumn >summer.Finally, control measures were put forward according to the air pollution characteristics of Wuhan City , aiming at providing scientific theoretical basis for the im-provement of air quality.
