摘　　要：对山西省晋中市榆次区近10年(1991年～2000年)大气中SO2污染物浓度进行监测,所得数据用方差分析进行分析.结果表明:夏季SO2污染最轻,没有超过国家《环境空气质量标准(GB3095-82)》日均浓度二级标准;春季和秋季污染情况比较接近,均超过夏季,但没有超过国家二级标准;冬季SO2污染最为严重,超过国家《环境空气质量标准》日均浓度二级标准(0.15mg/m3)的2倍～4倍.此外,对造成榆次区SO2污染严重的原因也进行了分析,并提出了有关的防治对策.The concentration of SO_2 pollution in the air in Yuci District,Jinzhong,Shanxi from 1991 to 2000 was monitored continuously,and the monitored date were analyzed by using analysis of variance.The results showed that:(1)The SO_2 concentration in the summers was gently and not more than the 2^(nd) grade standard of daily average for SO_2 in the air of the state 'Environmental Air Quality Standard (GB3095-82)'.(2)The SO_2 concentration in the springs and the falls were very closed,and more than in the summers,but were not more than the state standard for SO_2 in the air.(3)The SO_2 concentration in the winters was heavily and more 2 to 4 times than the state standard for SO_2 in the air.Moreover,the causes for the SO_2 pollution were analyzed,and the management strategies for the SO_2 in Yuci,Jingzhong,Shanxi,respectively.
