• 摘要：在土壤的模拟酸雨淋溶实验基础上,对不同地区不同层次土壤的缓冲能力进行了探讨;用硅作为指示性元素,研究了酸沉降作用下土壤矿物的风化特征;根据实验结果,对土壤中存在的两个缓冲体系进行了讨论。

• Abstract：Based on the results of leaching experiment using acid precipitation, the buffering capacities of several forest soils from China were studied. The weathering characteristics of soil minerals were investigated using Si as an index element. Two buffering systems in soil were discussed.

• Key words：soil  acid precipitation  buffering capacity  weathering
