摘　　要：利用2010年~2019年衡阳市城区大气硫酸盐化速率监测数据,研究分析硫酸盐化速率时间、空间污染特征,并采用秩相关系数法定量分析污染变化趋势.结果表明:大气硫酸盐化速率在2013年~2017年污染较重(相对于参考评价值),基本上呈倒V型变化,大多数年份下半年硫酸盐化速率要高于上半年,各功能区硫酸盐化速率污染特征表现为工业区>交通区>居民区>商业区.各功能区及全市总体硫酸盐化速率污染呈减轻趋势,但是污染减轻趋势没有显著意义,变化趋势不明显.Based on the monitoring data of air sulfation rate in Hengyang City from 2010 to 2019,the time and space pollution characteristics of sulfation rate were studied and analyzed,and the trend of pollution change was quantitatively analyzed by rank correlation coefficient method.The results showed that the air sulfation rate was heavily polluted in 2013-2017(compared with the reference evaluation value),which basically showed an inverted V-shaped change.The sulfation rate in the second half of most years was higher than that in the first half of the year.The pollution characteristics of sulfation rate in each functional area were industrial area>traffic area>residential area>commercial area.However,the trend of pollution reduction was not significant and the trend of change was not obvious.
