The result show ed the contents of Cd, Pb, Cu, Zn and As in the three species all presented in the order W( As) W( Zn) W( Pb) W( Cu) W( Cd) , but it varied in Cd, Pb, Cu, Zn and As absorption and distribution. Generally , their contents w ere hi her in the roots than in the shoots, which was as the same as control. T he absorption ratios of different heavy metal varied in the same species, and varied in stem / root. This study was impor tant for sustainable usin soil polluted by heavy metals and ecolo ical recovery.
