摘　　要：根据2011—2014年咸丰县空气质量监测数据及环境统计数据,在分析咸丰县大气环境现状的基础上,利用A值法对咸丰县大气环境容量和承载力进行了核算。结果表明:2011—2014年SO_2、TSP、NO_2的排放量呈现持续增长,年均浓度均满足《环境空气质量标准》(GB 3095—2012)中的一级标准;2011—2013年SO_2、TSP、NO_2的环境容量呈持续下降的趋势,分别下降了15.94%、1.84%、5.73%,2014年反而上升,但其环境容量并未达到饱和,仍有较多的剩余环境容量;2011—2014年3种污染物的承载力指数均小于-0.700 0,说明大气承载力处于高承载水平。According to air quality monitoring data and environmental statistics of Xianfeng County,during 2011—2014 the atmospheric environmental capacity was measured by using A value method. The results showed that the emissions of SO_2,TSP and NO_2 increased continually from^2011 to 2014,but the annual average concentration of three pollutants was up to standardⅠof Ambient Air Quality Standards（ GB3095-2012）.The environmental capacity of SO_2,TSP and NO_2 decreased constantly from 2011 to 2013,and the ratio was 15. 94%,1. 84% and 5. 73% respetively. The environmental capacity of three pollutants increased in 2014,and their emissions had not exceed their environmental capacity. The carrying capacity index of the three pollutants was less than-0. 700 0 from 2011 to 2014. It showed that Xianfeng County had more surplus environmental capacity and the atmosphere capacity was in a high level.
