摘　　要：根据1996-2015年株洲市二氧化硫的监测数据,分析研究了期间株洲市二氧化硫浓度水平,年、季度变化趋势及空间分布情况。结果显示:二氧化硫年均值变化呈"V"型,2003年后二氧化硫污染状况逐渐得到改善,2015年二氧化硫浓度已远远低于国家二级标准限值。不同功能区二氧化硫浓度水平明显不同,并且变化趋势存在差异。二氧化硫浓度与工业二氧化硫的排放量成正比。Based on the monitoring data of sulfur dioxide in Zhuzhou from 1996 to 2015 years, the concentration level of sulfur dioxide, the annual and quarterly change trends and the spatial distribution of sulfur dioxide in this period were analyzed. The results showed that the annual mean change of sulfur dioxide was V-shaped. The sulfur dioxide pollution was gradually improved after 2003, and the sulphur dioxide concentration in 2015 was far below the national secondary standard limit. The concentration of sulfur dioxide in different functional areas was obviously different, and the trend of variation was different. The concentration of sulfur dioxide was directly proportional to the emission of industrial sulfur dioxide.
