| 摘 要： | 本文综述了酸雨对酸性土壤性质的影响及由此产生的对植物生长的影响。酸雨pH值越低 ,我国南方酸性土壤酸化越严重 ,土壤中盐基离子淋失量越大 ,铝的活化量也越大。土壤中盐基离子大量淋失 ,造成植物必要养分缺乏 ;铝的活化能够对植物产生毒害 ,影响植物的正常生长 ,甚至引起植物的死亡

| Abstract: | This paper deals with effects of acid rain on characteristics of acid soil,which affectts plant growth.Soil acidification becomes serious and the amount of base ions and aluminum leached from acid soil increases when the pH value of the acid rain decreases.Leaching out of base ions from acid soil can cause plant nutrient lack.Release of aluminum from acid soil can make toxicity to plant,affect plant growth and even cause death of plant. |

| Keywords: | acid rain soil acidification aluminum aluminum toxicity plant growth |
