摘　　要：运用综合污染指数法对"十五"期间南通市大气环境质量现状进行评价,采用Spearman秩相关系数法对大气环境质量变化趋势进行了预测分析。结果表明:2001～2005年,南通市大气环境质量总体良好,呈现出先好后差的趋势,主要大气污染物是可吸入颗粒物(PM10)和自然降尘,两者总份额占73.38%。二氧化硫、二氧化氮、自然降尘、综合污染指数呈不显著上升变化趋势;可吸入颗粒物为不显著下降变化趋势。并剖析了南通市大气污染的主要原因,提出了改善大气污染的防治对策。The present atmospheric environmental quality in Nantong during the Tenth Five-Year Plan period was evaluated using comprehensive pollution index method, the variation trend of the atmospheric environmental quality was forecasted using Spearman rank correlation coefficient method. The results indicated that atmospheric environment quality of Nantong was generally good and presented a trend from good to bad in period of 2001 to 2005. The major air pollutants were inhalable particulate matter （PM10） and natural dropping dusts because both of them account for 73. 38%. SO2, NO2, natural dropping dusts and comprehensive pollution index showed an unobvious rising trend and unobvious dropping for PM10. The major factors causing the atmospheric pollution were analyzed in Nantong, and some countermeasures were put forward in order to control atmospheric pollution.
