摘要

In order to further research the relevant theories concerning how greenery waste affect metal speciation in the soils, the influence of greenery waste on the speciation of Cu, Zn, Pb and Cd in the soils is analyzed in this paper. Based on previous studies, yellow soil and calcareous alluvial soil contaminated by Cu, Zn, Pb and Cd are used for lots of indoor culture experiments where the influence of greenery waste of different additive amounts and different culture time on the speciation of Cu, Zn, Pb and Cd in contaminated yellow soil and calcareous alluvial soil. Results are obtained, and hopefully they may contribute valuable references for involved researchers.
