摘　　要：针对石家庄市近年来大气污染严重并导致部分月份出现酸雨现况,通过模拟不同pH酸雨的淋溶试验,较深入的研究了酸雨对石家庄市褐土和潮土矿质元素的影响。结果表明:褐土和潮土中SO2-4受酸雨的影响较大;盐基阳离子对酸雨的敏感性顺序为Ca2+>Mg2+>Na+>K+,揭示了褐土和潮土具有较强缓冲酸雨的能力。Based on the fact that the serious air pollution in Shijiazhuang leads to acid rain in some months and acid rain can affect mineral elements in soil, this paper did a deep research on its impact on mineral elements through rinsing experiment with different pH. The result showed that SO^(2-)_4 both in cinnamon soil and alluvial meadow has close relationship with acid rain; The sensitive order of various salt kation to acid rain is Ca^(2+)>Mg^(2+)>Na^+>K^+; This paper also disclosed both cinnamon soil and alluvial meadow had strong cushion capacity to acid rain.
