一、前言我国的酸雨污染问题不仅是当今严重的环境问题，而且已威胁着某些地区的森林生态系统，西南地区尤为严重。

Has weak activation and transfer under acid rain effect and redeposition will take place during the course of their moving from surface soil to deep soil.

酸雨作用下离子的迁移过程客观存在，这一点从土壤电导率研究结果中得到了确认。

Has weak activation and transfer under acid rain effect and redeposition will take place during the course of their moving from surface soil to deep soil. Contrasted quality standard analysis of surface water, ground water and drinking water, these elements will not bring about negative effect to the water environment and ecological environment of soil.

进一步相态分析结果表明，受酸雨淋滤作用的影响，离子的迁移主要发生在盐基离子上，具体表现在经酸雨淋滤后表层土壤水溶态组分中盐基离子浓度降低，与此相对应的是Al离子浓度显著增高，一个直观的反映是土壤的电导率降低。

The board style platform of the cabinet body is easy to rust away and rot in under special environments such as acid rain and southern maritime climate.

柜身的板式平台在在南方沿海海洋性气候和钢铁企业所处的酸雨的特殊环境下容易锈蚀、穿烂。

The results showed that the amounts of base cations leached from calcareous soils and coastal solonchak were lower than the cation exchange capacity and the releasing amounts of Al3+ being lower than 0.40mmol·kg-1 all the way under the treatment of simulated acid rain with each pH value from 2.5 to 5.6,so the H+ buffering...

结果表明，石灰土和滨海盐土的阳离子淋溶量低于阳离子交换量，土壤主要处于阳离子交换缓冲范围和碳酸盐-硅酸盐缓冲范围，Al释放量一般低于0.40mmol·kg~(-1)，铁铝土纲系列土壤在阳离子释放总量超过阳离子交换量后，淋溶液pH值急剧下降，此时Al淋溶量明显增加，质子缓冲转向Al缓冲范围，其释放量决定于土壤富铁铝化程度的高低和活性Al含量的多少，紫色土在低pH模拟酸雨淋溶下，由于含大量硅铝率较高的易风化原生或次生矿物，盐基释放量高于CEC，但Al释放量未明显增加，淋溶液pH也较稳定，土壤尚处于矿物风化为主的硅酸盐缓冲范围。

The vertical distribution and the aerosol followed by southeaster from sea in summer are other reasons of acid rain .

同时，特殊的边界层气象条件及夏季东南风带来的海洋气溶胶对酸雨的形成也有一定影响。
