摘　　要：基于2013—2022年ERA5再分析资料和饶阳国家气候观象台地面观测资料,采用A值法计算了衡水市大气环境容量,并分析其变化趋势。结果表明,近10年来,衡水市大气环境容量呈波动变化,大气环境容量较大的年份为2013、2014、2019和2022年,较小的年份为2015、2016、2018和2020年。一年中,春季平均大气环境容量最大,为47.64万t;冬季平均大气环境容量最小,为31.33万t。一天中,02:00、05:00、23:00较小,最小为05:00的12.34万t,08:00、14:00、20:00较高,最大为08:00114.61万t,白天的大气环境容量大于夜间。Based on the ERA5 reanalysis data and the surface data of the observation station of Raoyang Meteorological Bureau from 2013 to 2022,the atmospheric environmental capacity of Hengshui was calculated by A value method,and its changing trend was analyzed.The results show that the atmospheric environmental capacity of Hengshui has fluctuated in the past 10 years.The higher years were 2013,2014,2019 and 2022,and the lower years are 2015,2016,2018 and 2020.In a year,the maximum atmospheric environmental capacity in spring was 476400 tons,and the minimum in winter was 313300 tons,which gradually decreases from spring to winter.During the day,02:00,05:00 and 23:00 are lower,the lowest was 123.4 thousand tons at 05:00,and it was higher at 08:00,14:00,20:00,the highest was 1146.1 thousand tons at 08:00.The atmospheric environmental capacity during the day was higher than that at night.
