The study selected the ornamental plant remediation system as the study object, discussed the effects of the elevated CO2 on the Cd and HHCB accumulation efficiency by Bougainvillea spectabilis, and analysed the ecological function by detecting the rhizosphere bacteria number, enzymatic activity, and organic carbon. Results showed that the combined Cd and HHCB contamination under elevated CO2 showed no obvious inhibition function to the growth of the plant. Especially the elevated CO2 treatments (750μL/L) significantly facilitated the plant growth and contaminant accumulation, furthermore, the rhizosphere bacteria number reached the maximum. Urea enzymes activity showed significant difference under the different treatments. The addition of HHCB and the elevated CO2 facilitated the organic carbon in the rhizospheric soil. In summary, Bougainvillea spectabilis has potential to be used for remediating the combined Cd and HHCB contaminated soil remediation under elevated CO2.
