Abstract：Eight herbaceous plants were chosen for the study of soil-reinforcement experiments.The maximum strength of herb roots and the corresponding root diameters were measured.Then the tensile strength was calculated on the basis of the measurement,which was used as a criterion for comparison of various roots for soil-reinforcement.The results indicate that the average tensile strength of Pennisetum alopecuroides (Linn.)Spreng is the greatest,26.46MPa,followed by Cornilla varia L,25.03MPa,Trfolium Reports L,22.01MPa,Buchloe dacyloides Engelm,20.93MPa，Fes-tuca arundinacea Schreb,15.84MPa,Medicago sativa ,15.82MPa,Cynodon dactylom (L).Pers,14.54MPa,and Setaria viridis,11.99MPa.
