摘要
根据2016~2020年贵州省9个地级市的降水监测数据,分析了贵州省酸雨变化趋势。结果表明:“十三五”期间,贵州降水酸度总体呈减弱趋势,无酸雨污染;降水中SO_(4)^(2-)离子当量浓度呈下降趋势,NO_(3)^(-)离子当量浓度呈上升趋势;SO_(4)^(2-)/NO_(3)^(-)呈下降趋势,贵州降水致酸因子由硫酸型逐渐过渡为硫酸与硝酸混合型。
According to the precipitation monitoring data of 9 prefecture-level cities in Guizhou Province from 2016 to 2020,the trend of acid rain in Guizhou Province is analyzed.During the Thirteenth Five-Year Plan,the acidity of precipitation in Guizhou Province showed an overall weakening trend,and there was no acid rain pollution;the equivalent concentration of SO_(4)^(2-) ions in the precipitation showed a downward trend,and the equivalent concentration of NO_(3)^(-) ions showed an upward trend.SO_(4)^(2-)/NO_(3)^(-) showed a downward trend,and the acid factor of precipitation in Guizhou Province gradually transitioned from sulfuric acid to mixed sulfuric acid and nitric acid.
