The pot and plot experiments were conducted to study the effects of intercropping on the remediation efficiency of Trifolium?repens plant under lead (Pd) contamination. Salvia splendens, Callistephus Chinensis and Iris germanica L. were intercropped with Trifolium?repens respectively to study the influences of different intercropping combinations on the growth of Trifolium?repens and Pd accumulation. The results showed that intercropping with Iris germanica L. improved the shoot biomass and the whole plant biomass of Trifolium?repens, but intercropping with Salvia splendens and Callistephus Chinensis reduced the shoot biomass and whole plant biomass compared with monoculture of repens. In the intercropping system, the total biomass of plants always fell in between the monoculture of two species. By intercropping with Salvia splendens, Callistephus Chinensis and Iris germanica L., all the Pd contents in shoots of Trifolium?repens increased, by 11.39%, 17.88% and 42.18% respectively compared with Trifolium?repens monoculture in pot experiment, and by 2.64%, 13.22% and 23.94% respectively in plot experiment. The total Pd accumulation in shoot of Trifolium?repens and Iris germanica L. intercropping system was higher than the monoculture of the two species respectively, and the other intercropping treatments were between the monoculture of the two species. In plot experiment the total Pd accumulation in shoots per unit area in Trifolium?repens and Iris germanica L. intercropping system was highest of all intercropping?patterns, which reached up to 242.777 mg/m2, improved by 371.83% and 8.38% respectively compared with the monoculture. The?removal?rates?of Pb in soil of Trifolium?repens and Iris germanica L. intercropping system were the highest of all intercropping?patterns, which reached up to 15.11%, improved by 326.84% and 10.70% respectively compared with the monoculture. Therefore, in terms of the whole restoration efficiency, the Trifolium?repens intercropping with Iris germanica L. performed the best，which could be used to enhance the remediation effect of Pd contaminated soil.
