摘要： 对雅安市区2001~2003年的大气污染因子(包括SO2、NOx和降尘)和降水进行了研究,结果表明,雅安市区酸雨属于硫酸型酸雨,其形成主要是因为上风方向的大气中SOx、NOx等污染物质含量超标,并随气流扩散到雅安市区上空,与"华西雨屏"特殊自然现象和雅安市山涧河谷盆地的特殊地形共同作用的结果。

关键词: 雅安市区, 酸雨, 形成机理

Abstract: According to the analysis of air pollution factor(including SO2, NOx and fall dust) and rainfall in between 2001 and 2003, the result indicates that the acid rain of Yaan urban area belongs to sulfuric acid. It's mainly due to pollution in upwind, the content of pollutant such as SO2 and NOx is above-norm, which are carried by windstream to Yaan urban area. It is also influenced by natural phenomena named the Huaxi Rain Screen and the special geography shaped by the mountain and river valley.

Key words: Yaan urban area, acid rain, mechanism
