Abstract:: Taking thirty nine ornamental emerged plants in Hangzhou as test materials，the nitrogen and phosphorus content and biomass of the above-ground part of ornamental emerged plants were tested，so that their water purification potential were estimated and sized down in this paper，combined with our specific construction method of the artificial floating island.The results showed that Sagittaria trifolia var. sinensis，Alisma candliculatum，Caldesia reniflrmis，Sagittaria montevidensis，Lythrum salicaria possessed high potential of removing phosphorus and Caldesia reniflrmis，Colocasia antiquorum，Canna generalis，Colocasia antiquorum，Juncus effuses，Lythrum salicaria possessed high potential of removing nitrogen.Except of the nutrient removal ability，other factors such as tolerance of the submerged environment and resistant of insects should be consulted in application of the artificial floating island.According to our experience，Caldesia reniflrmis and Acorus calamus were suitable to be planted in the artificial floating island.
