Abstract: This study deals with the content of heavy metals such as Cu,Pb,Cr,Zn,Cd of forest litter in Nanjing urban forests. The results showed that the heavy metal content in forest litter was higher than that of soil background value and the plant content value of above ground part, the heavy metal content of different layers was Y layer>L layer, the order of heavy metal content in different plots was: urban district and outer suburbs>city suburbs, the coefficient of variation of different communities was between 17.91% and 63.47%, the order of different heavy metal content in forest litter was:rn(Zn)>m(Cr)>m(Pb)>m(Cu)>m(Cd), the content of Zn is 0. 909 2 kg/hmz.
