A study was carried out to explicate the characteristics of Pb uptake by four herbaceous(Lolium perenne

Cynodon dactylon

Poa annua

Agrostis stolonifera)in acid yellow soils

in order to provide scientific basis for improvement of the ecological environment.Adopt a pot experiment

determined the concentration of lead in the roots and shoots of the four herbaceous.S/R

bioaccumulation coefficient

total heavy metal translocation of lead

root tolerance index of the four herbaceous were also investigated.Correlation analysis between Pb contents in plants and Pb-added concentration in soil four kinds was marked

coefficient of correlation were greater than 0.90;To sum up the four indexes

the resistance to lead was Agrostis stolonifera>Lolium perenne>Poa annua>Cynodon dactylon

four plants without stress

especially can endure and grow normally in the pollution soil of 3 000 mg Pb/kg

suited much more for phytoremediation of Pb-contaminated soils.
