Abstract: Cu2+ adsorption of 24 soil samples gathered out of 4 soil layers(0—10、10—20、20—40、40—60 cm) of 6 different types of forests in Anji,Zhejiang were determined to explore relationship of Cu2+ adsorption with organic matter content,CEC,pH and particle composition.Results show that in terms of Cu2+ adsorption the six types of forests are in the order of broadleaved deciduous forest>shrubbery>tea grove>broadleaved evergreen forest>bamboo grove>pine forest.Cu2+ adsorption decreases with the depth of the profile.Organic matter content and CEC are the two major factors affecting soil Cu2+ adsorption.Based on the findings,a model is established to illuminate the relationship of Cu2+ adsorption with organic matter content and CEC.

Key words: soil, copper, forest type, heavy metal, physical and chemical property, adsorption, affecting factor
