摘要
收集了2011—2015年云南省20个主要城市设置的31个降水监测点的监测数据,分析了云南省“十二五”期间酸雨的污染状况和时空分布特征,结果显示:云南省“十二五”期间酸雨污染总体呈下降趋势;酸控区7个城市中,降水pH值在4.39~7.15,降水pH年均值低于5.6,已受酸雨污染的城市有个旧、楚雄2个,占酸控区城市总数的28.6%;云南省酸雨污染问题不突出。
The monitoring data of thirty-one precipitation monitoring sites in twenty cities in Yunnan province from the year of 2011 to 2015 were collected. The pollution status and its spatial and temporal distribution of acid rain during the time period of the 12th five-year plan were examined. The results showed that the general pollution status was decreasing. The pH value of seven cities among all cities fell between 4.39 and 7.15. The annual mean was less than 5.6. Two cities, namely Gejiu and Chuxiong, were polluted by acid rain, which was accounted for 28.6% of all cities. Therefore, the acid rain pollution in Yunnan is not obvious.
