%X This paper dealt with the relationship of pH value and the characteristics of Si2+ and Al3+ of leaching solutions under the treatment of simulated acid rain in main soil types collected from South China. The results showed that amounts of Si2+ and Al3+ releasing were decided mainly by pH value of simulated acid rain.When pH was lower than 3.0,the amounts of releasing increased sharply.Otherwise,the amounts of Si2+ and Al3+ released from soils increased slowly.As the addition of H+ concentration in soil solution,the amounts of released Si2+ and Al3+ increased with the acceleration of the hydrolysis reaction of soil minerals,which usually were the most important soil weathering process.
