    Abstract:

    Soil column is used to study the characteristics of the movement of copper in uprightness direction in brown soil which is in one year rainfall condition in Taian.The result shows that the higher the content of copper in soil,the more leaching loss,the content of SUB-Cu and RES-Cu increases by 28.57% to 33.49%.In the soil of high content of copper,the proportion of EX-Cu decreases by 9.97% to 10.48% and the movement of copper decreases by 15.54% with the content of calcium increasing;with the increasing of brown coal input to soil,the content of ex-Cu in the surface layer decreases,the leaching loss of copper decreases distinctly which moves to the layer of 5~10 cm and the content of OC-Cu increases by 22.76%~36.07%.
