Abstract
Based on the data of atmospheric precipitation monitored by Xichang environmental monitoring station from 2011 to 2015,the characteristics and trends of acid rain pollution in recent years in Xichang City were analyzed.The results showed that the precipitation pH value and acid rain frequency were stable,changing in light acid rain area and nonacid rain area.The change rate of precipitation in urban and suburban area were basically equal.Acid rain pollution was not local pollution,precipitation appeared from April to October,lowest monthly precipitation Ph value was 4.76,which occurred in August 2012.Highest acid rain frequency value 87％ appeared in September 2012.Chemical ions in precipitation were mainly SO42-,NO3-for anions,NH4+,Ca2+ for cations,the variation of them were stable,and the precipitation was more affected by SO42-in Xichang City.关键词
