摘　　要：对1993-2002年芜湖市区大气SO2进行了连续10年的观测,结果表明,芜湖市区大气SO2质量浓度10年平均值为0.023 5 mg/m3,由1993年的0.052 mg/m3减少到2002年的0.012 mg/m3,年平均减少率为4%.2000年以来减少速度加快,大气SO2质量浓度日变化总特征是早晨高、午后低,季节变化是冬季、春季高,夏季、秋季低.同时对芜湖市区大气SO2发展趋势作了分析,并提出了防治和减轻污染的建议.SO2 in Wuhu was measured from 1993 to 2002 continuously. The average of SO2 concentration of these 10 years in Wuhu was 0. 012 mg/m^3, and it decreased from 0. 052 mg/m^3 to 0. 012 mg/m^3, with an annual average rate of 40/40. Especially it decreased more quickly from 1998 to 2002. The daily SO2 concentration is high in the morning and low in the afternoon. The monthly concentration of SO2 is low in summer and fall, high in winter and spring . By calculating the developing trend, suggestions to reduce pollution are put forwarded.
