摘要
分析了南通市2001-2005年市区等7个监测站所监测的二氧化硫(SO2)、二氧化氮(NO2)、可吸入颗粒物(PM10)和自然降尘(DF)结果的年变化趋势,根据国家标准利用模糊综合评价模型对各区各年大气环境质量状况做出了合理的综合评价.结果表明,2001-2005年,南通市大气环境质量总体良好,但有下降趋势.并由模型中各污染因子的权重判断出SO2、PM10和DF是南通市市大气质量的制约因子.
Fussy comprehensive evaluation was applied to evaluate atmospheric environmental quality during the period from the year of 2001 to 2005 based on the data from the city' s seven automatic sampling stations,including the variables of SO2, NO2, PM10 and DF. According to the evaluation,the ambient environmental quality in Nantong was generally good during this period, but with a downward trend. By weighing of the pollution factors in this model,the predominate factors of air pollution were SO2 ,PM10 and DF in Nantong.
