%X The study on the Cu forms in Cynodon dactylon rhizosphere soil of copper tailings yard in Tongling City, Anhui Province showed that among the test Cu forms, the amount of residual form occupied the majority, while that of exchangeable form was relatively low. Compared with non-rhizosphere soil, rhizosphere soil had a higher organic matter content but a lower pH. With the growth of C. daetylon, the contents of organically combined and exchangeable Cu in rhizosphere soil increased by 7.89% and 5% , respectively, while those of carbonate-combined and Fe-Mn oxidescombined Cu decreased. The growth of C. daetylon accelerated the transformation of Cu forms in rhizosphere soil, and decreased the rhizosphere soil Cu content through its absorption.
