Submerged plants are one of the main primary producers of ecological systems in shallow lakes, not only provide food sources and spawning substrates for aquatic animals, hatch, breed and refuge places, but also improve the transparency of water bodies, maintain the physical and chemical environment stability of the water bodies and the substrates, simultaneously effectively absorb and degrade toxic and harmful substances such as nitrogen and phosphorus nutrient salts, heavy metals, organic pollutants and the like, inhibit cyanobacterial bloom, and play an important role in maintaining the structure and the function of the aquatic ecological systems. However, due to long-term overload pollution discharge, lakes in many plain areas face eutrophication problems, the coverage rate of aquatic plant communities, particularly submerged plants, is sharply reduced, the biodiversity is reduced, and the aquatic ecosystem is degraded. In view of the important role of the submerged plants, the restoration and reconstruction of submerged plant communities become key targets and core measures for the ecological restoration of eutrophic lakes.
However, the recovery and reconstruction of submerged plant communities in eutrophic shallow lakes is a very challenging technical problem. Large shallow lakes are generally affected by wind and waves greatly, and the coverage of aquatic vegetation is reduced to aggravate the wind and waves. The stormy waves and the shallow water environment cause the sediment to be re-suspended to release nutritive salt, and the turbidity of the water body is increased. Further leading to the aggravation of lake eutrophication, the mass propagation of algae and the further reduction of water transparency. Too low transparency results in strong underwater light attenuation and difficulty in survival of submerged plants. In addition, the aquatic vegetation is more difficult to recover and rebuild due to the wind wave impact. Therefore, ecological restoration of eutrophic shallow lakes cannot rely solely on reducing the pollution entering the lake, and requires restoration and reconstruction of submerged plant communities. The technical problems of reducing wind waves, inhibiting bottom mud from resuspending, improving the transparency of a water body and the like need to be solved for recovering and reconstructing submerged plant communities in eutrophic shallow lakes.
