摘要
用空气污染指数法,进行空气质量评价;用主成分分析法进行污染因子分析;用秩相关系数检验法作污染趋势分析。并根据淮安市2004-2007年实测空气质量日报资料,说明上述方法的应用。
Based on air quality data which were measured daily from 2004 to 2007 in Huaian City, Jiangsu Province, air pollution index was used for air quality evaluation. Principal component analysis was used to analyze the pollution factors and pollution trend was analyzed with rank correlation coefficient test.
