摘　　要：This study was conducted to analyze the spatial distribution of SO2 mass concentration around baking barn groups. A bulk curing barn group was selected as monitoring object, and SO2 concentration around it was monitored for 2 years. The results showed that the SO2 mass concentration within 30-130 m from the baking barn group exceeded the standard, and with the ground as reference, the SO2 mass concentration at the position 0.9-2.1 m from the ground exceeded the stan- dard. According to the limit value of the SO2 mass concentration for sensitive crops, the SO2 mass concentrations over the standard were concentrated within the range of 200-300 m. On the basis of establishment of ＂sulfur control＂, ＂sulfur reduction＂ and ＂sulfur avoiding＂ system, the SO2 emission status of baking barn groups could be improved from the conversion of heat supply method, the utilization of clean en- ergy and adjustment of crop sensitive period and sensitive area.选取烤烟烘烤工场为监测对象,对其附近SO_2质量浓度进行为期两年的监测,分析了烘烤工场周围SO_2质量浓度空间分布。分析结果表明:SO_2地面质量浓度高值出现在烘烤工场顺风向50 m的频率最大,且离地面0.9~2.1 m空间范围的SO_2质量浓度超出限值;烘烤工场顺风向200~300 m内的作物成长环境内SO_2质量浓度超出阈值。建立烘烤工场的"控硫"、"降硫"、"避硫"系统,可以从供热方式的转换,洁净能源的使用以及作物敏感期和敏感区的调整来改善烘烤工场超标排放SO_2的现状。
