Background

The aquatic plants are important components of the lake ecosystem and play an important role in maintaining the balance of the ecosystem and improving the water environment. The aquatic plant community protection and reconstruction are not only the key for keeping a 'clear water type' lake, but also important means for controlling the eutrophication of the lake and improving the water quality. The basic environment is the foundation for the survival of aquatic plants, and the physicochemical properties of the basic environment determine whether the plant roots can obtain sufficient nutrient elements. The stability of the substrate then directly affects the colonization and survival probability of the plant. In large shallow lakes, waves are broken when the water depth is reduced in the process of spreading to lakeside zones, and wave currents are formed to continuously wash and erode the coastal substrate, so that the substrate stability is low, and the vegetation ecological conditions are deteriorated. In open water areas, the continuous disturbance of wind waves also has a large scouring effect on the substrate. If the base is eroded, the nutrient salt needed by the growth of the plant can not be effectively supplied, and the root system of the plant is damaged because the sediments at the bottom of the lake are eroded and exposed to various dynamic disturbances in the lake, and simultaneously the plant loses the fixation point, the growth position is changed, and the vegetation community is seriously damaged. Therefore, the designed in-situ conservation device for the aquatic plants in the shallow lake, which can weaken basal scouring, has important significance for preventing the vegetation community from degrading, maintaining the vegetation community and stabilizing an ecological system.
