摘要
近年 ,酸雨是世界上最严重的环境问题之一。峨眉山位于四川盆地的西南缘。峨眉山酸雨频率达到85 .4%,雨水 p H值平均为 4.37。冷杉分布于海拔 170 0 m～ 30 98m区域 ,森林遭到破坏。为了弄清峨眉山污染物质的来源 ,从 1998年 4月开始在 2 2个取样点每月采集水样。本文中主要论述 1998年 6月的雨水化学成分特征。
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. In this paper, chemical characteristics of the rain in June 1998 is reported.
