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SO2、TSP、NO2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SO2 、TSP、NO2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.
Abstract
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 SO2,TSP and NO2 increased continually from 2011 to 2014,but the annual average concentration of three pollutants was up to standard Ⅰ of Ambient Air Quality Standards(GB3095-2012).The environmental capacity of SO2,TSP and NO2 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 cartying 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.
