In this article, a method of selecting eutrophication-remediated plants is proposed, which established the selecting index that is based on the ability of removing nitrogen (N) and phosphorus (P) rapidly and efficiently. This article combines parameters of absorption kinetics and growth kinetics to reflect their ability of removing nitrogen and phosphorus of the selected plants. The results showed: (1) The optimum growth conditions of 3 species respectively, temperature 31.30, 23.38, 26.10°C; salinity 32.10, 21.10, 22.77; light intensity 287.23, 229.07, 216.65 μmol/(m2·s). (2) Under their optimum growth conditions, the maximum absorption rates (Vmax) respectively were 57.83, 54.26, 52.32 μmolN·dwg-1·h-1, 3.142, 2.802, 2.132 μmolP·dwg-1·h-1. (3) Selecting index Y and Y′ were 13.93, 5.03, 10.84, and 5.99, 1.92, 4.60 for N; 59.40, 58.67, 57.92, and 0.41, 0.23, 0.27 for P, respectively. Both Y and Y′ of G. lichenoides for removing N and P were bigger than those of G. lemaneiformis and G. tenuistipitata var. liui.
