Abstract：Toscreenoutnewpotentialcrium（Ce）acumulatingplants forcontaminatedsoilremediation，asandcultureexperient wasconductedtostudytheCeaccumulationcharacteristicsofleavers（GalimaparineL）treatedwithCeatdiferetconetatios. TheresultsshowedthatwiththeincreaseinCeconcentrationintenutrientsolution，theplantheight，ootlengthandbioasof cleavers showeda trend offirst increasing and then decreasing，reaching the maximums when the Ce concentration was 15mg/L . The Ce content in cleavers showed an increasing trend. When the Ce concentration in the nutrient solution was 120mg/L ，the Ce content in roots and shoots was 3 052.06 and 482.87mg/kg ，respectively. The roots and shoots of cleavers showed the Ce bioconcentration factors greaterthan1andthetranslocationfactorsbelow1，whichindicatedthatCe was mainlyaccmulatedintherots.The maximumCe accumulation amountsin the rootsand shootswere 30.61 and 47.94μg/plant ，respectively.Therefore，cleaverswasapotential CeacumulatingplantandcouldbeusedasapotentialphytoremediatiomaterialforCe-contaminatedsoilsinwinterandspringadcool climate regions.
