| Abstract: | Twenty-eight soil profiles studied were collected from the eastern China. They be-long to brown soil,drab soit,yellow brown soil,brown limestone soil and red limestone soil. The concentrations of Ca,Mg in soils decrease and the concentrations of Fe,Al,Zn, Pb,Cd and Hg increase from north to south. There is no significant correlation between the element concentrations and soil organic matter contents. Statistically there is a most significant positive correlation between the concentrations of Ca,Mg and pH,while there is a most significant negative correlation between the concentrations of Fe,Zn,Cd and pH,and a significant negative correlation between Pb concertration and pH. There is a most significant negative correlation between concentrations of Ca,Mg and clay content, and a most significant positive correlation between Fe,Al,Zn,Pb,Cd,Hg and clay con-tent. The concentrations of Ca,Mg decrease,and Fe Al,Zn,Pb,Cd and Hg increase in the processes of acidification and clayization accompanied with the increase in tempera-ture and rainfall. |
