Abstract: Susong Huayang Lake, as the typical linking lakes of the Yangtze River, is one form of the ecological barrier in the eastern China. It has a surface area of 183 hm2. In order to strengthen wetland protection and restoration of aquatic vegetation, from March 2015, three types of ecological reconstruction experiments have been carried out. Main applied measurements include cultivating Zizania latifolia seeding, Nuphar pumilum seeding, Nelumbo nucifera rhizome, broadcasting Trapa quadrispinosa fruit, Vallisneria natans fruit, Euryale ferox seed and so on. The results showed that the seeding of Zizania latifolia and Nuphar pumilum can grow well with 14 aquatic macrophyte association being set up. The coverage of Ass. Zizania latifolia and Ass. Nelumbo nucifera are 90% and 95%, respectively, while the biomass of Ass. Zizania latifolia and Ass. Nelumbo nucifera are 10.57 kg/m2 and 2.05 kg/m2, respectively. All the Trapa quadrispinosa fruits, Vallisneria natans fruits and Euryale ferox seed can germinate early and form seedling, but gradually disappear affected by the fishery. According to the result of this study, it is important to rehabilitate Ass. Zizania latifolia and Ass. Nelumbo nucifera in littoral of lakes, and to facilitate the grow of submerged plant communities and floating plant communities by controlling the fishery breeding intensity, hydrological conditions, and establishing submerged macrophytes and floating macrophytes in the lake.
