摘要
基于眉山市2015年大气降水监测数据,分析了眉山市大气降水现状及化学特征。结果表明,2015年眉山市降水酸雨发生频率为零,属非酸雨区。降水中pH值变化不大,电导率与降水量成反比关系,主要阴离子为SO_4^(2-)和NO_3^-,主要阳离子为Ca^(2+)和NH_4^+。总阴离子浓度大于总阳离子浓度,属硫酸型降水。
Based on the monitoring data of atmospheric precipitation in Meishan in 2015,the present situation of atmospheric precipitation and the chemical characteristics were analyzed.The results showed that the frequency of precipitation acid rain in Meishan was zero in 2015.
