| 摘 要： | 对芜湖市四褐山杉木林土壤进行室内模拟酸性降雨,研究该土壤对酸雨的缓冲性能。结果表明：土壤经酸雨处理后,在１～７天内有酸化的趋势,７～１４天时具有明显的缓冲作用,１４天后基本上又恢复到原来的ｐＨ值状态;土译不同浓度酸雨的缓冲能力随酸性的降低而增加;不同土层之间的缓冲性能呈现一定的规律。

| Abstract: | According to the changes of pH value in different soil layers treated by various acid rains in different time, this article has been investigated the buffer capacity of the soils collected from China fir forest in Wuhu Sihe mountain. The results showed that the soils trend to become acids in first seven days and reveal significant buffer capacity in thd following seven days, then returned to the original pH value meanwhile. Buffer capactiy got stronger as the acidity of the simulated rain decreased and specific laws prevailed on the capacity among different layers of the soils. |
