【摘要】 对2011—2017年间重庆市武隆区降水进行了收集和分析。结果表明,2012—2017年的6年里,武隆区降水pH逐渐升高、酸雨率逐渐降低,2017年整体pH高于5.60,酸雨控制具有初步效果;pH值从高到底依次为春>夏>秋>冬,电导率值从高到底依次为冬>春>夏>秋;降水中各主要离子的标准差从小到大排序依次为:Mg²⁺<F^-<Na⁺<Ca²⁺<NH⁺₄<NO^-₃<K⁺<Cl^-<SO■;武隆区降水中的SO■、NO^-₃、NH⁺₄、Ca²⁺、Cl^-、K⁺为主要阴阳离子,总占比为97.37%。更多还原

【Abstract】 The precipitation in Wulong district of Chongqing during 2017 and 2011 was collected and analyzed. Results show that the pH of precipitation increases gradually and the rate of acid rain decreases gradually in Wulong area since the year 2012 to 2017.The pH value of precipitation in 2017 is totally abpove 5.60,Acid rain Control has preliminary effect; The pH value arrange from high to low is Spring,summer,,autumn, and winter. The electrical conductivity value from high to low is Winter, Spring,summer and autumn in sequence. The standard deviation of the main ions in precipitation sorted from small to large is Mg²⁺<F^-< Na⁺<Ca²⁺<NH⁺₄<NO^-₃<K⁺ <Cl^-<SO■. The SO■, NO^-₃, NH⁺₄, Ca²⁺, Cl^- and K⁺ of precipitation in Wulong area are the main negative and positive ions, the total proportion is 97.37%.更多还原
