Nowadays, acid rain is one of the most serious problems in the world. The Emeishan is located on the southwestern margin of the Sichuan Basin. The frequency of acid rain in the Emeishan reached 85.4% with a mean pH value of 4.37. Fir trees distributed mainly in the area of 1 700 m to 3 098 m above the sea level suffered damage.Rain samples have been collected monthly to clarify the sources of pollutants in the Emeishan since April,1998 at 22 sampling stations.
