Based on a strict experimental design,four soil types that are sterile land,manmade Masson Pine forest soil,Camphors forest soil and cultivated soil from Nanshan Park were selected to be leached by simulated acid rain of four pH values.The results show that all the four types of soil had some capability of anti-acidification and in this range,the pH of leached solution and elements in it could keep relative stable.However,out of this range,the pH of leached solution dropped greatly and the canon Al,Ca,Mg in...
