摘要
选取2013年天府新区内7个站点的风速、降水量、总云量/低云量实际观测数据,以箱式模型为基础,利用季节平均计算公式,重新计算了其四季A值,对天府新区的4种主要污染物SO2、NO2、PM2.5、PM10的季均大气环境容量进行了核算。研究结果表明:(1)天府新区2013年四季A值分别为0.79、0.82、0.49和0.40;(2)天府新区4种污染物的季节环境容量在夏季均为最大值,冬季均为最小值;(3)干沉积清除量与化学转化清除量在4项清除量中的数值最小,湿清除量所占比重最大,是造成研究区年内分布不均的主要因素。
This paper selects the actual observation data of wind speed, precipitation, total cloud amount/low cloud amount in Tianfu New District in 2013. Based on the box model, the total control coefficient A of geographic regional was recalculated by using seasonal average calculation formula. The average environmental capacity of the four main pollutants in Tianfu New District was calculated. The results show that:(1) the seasonal A values in Tianfu New District In 2013 were 0.79, 0.82, 0.49 and 0.40;(2)The pollutants in Tianfu New District are the largest in summer and the smallest in winter;(3) The dry sediment removal and chemical conversion removals were the smallest among the four removals,the wet removals accounted for the largest proportion, which were the main factor causing uneven distribution within the study area during the year.
