Selection of Wetland Plants planted in floating bed in one estuaries of Dianchi lake
The study were carried out to select the macrophyte planting in floating bed, which could be applied to the ecological restoration of the estuary of Daqing river to Dianchi Lake.There are five indigenous emerging species (Canna generalisBai1ey, Cyperus Alternifolius, Typha angustifoliaL. Zizania caduciflera, Iris tectorum), cultured in the stressed conditions of the serious pollution river water. These used as the selecting indices are the removal rate of CODCr total phosphorus(TP), total nitrogen(TN), phosphate(PO4 3-), ammonia nitrogen(NH3-N), the ability of resistance oxygenation: MDA content, proline content and 1 -naphthylamine changes of root oxidation. Comprehensive analysis of the index show that five options plants have a big difference in the adaptability of pollution stress and the removal of pollutants, of which Canna and Iris have the best adaptability, and removal efficiency. Therefore, Canna and Iris could be chosen as ideal species in floating bed for the restoration.
