摘      要：Bioretention is a best management practice which uses vegetation to improve the pollutant removal rates in the rain water *** select the best plant species to remove multiple pollutants in a bioretention system,we tested thirty species of plants in a laboratory in Beijing,*** found that the ability of the plants to reduce concentrations of heavy metals including cadmium(Cd),lead(Pb),zinc(Zn),and ammonium(NH4?–N)is more than90%.The removal efficiencies for NH4?–N,nitrate(NO3-–N),total phosphorus,and copper(Cu)varied markedly among plant *** single overall best plant was not easy to be *** select the best plant species,we used a dynamic neural network to establish an assessment index system,assessment criteria,and an assessment model that is used here for the first time for multiple pollutants’*** the theory and model,we discovered that Plantago asiatica *** Digitaria sanguinalis(L.)*** the overall best plants for removing the seven *** paper will provide a simple and useful guide for the comprehensive assessment of multiple pollutant removal by plants in complex ecological systems.
