Ecological restoration method for steep lakeside zone of polluted lake with shallow water type bottom mud

Abstract

The invention discloses an ecological restoration method for a steep lakeside zone of a polluted lake with shallow water type bottom mud. The method comprises the steps: ecological desilting is carried out on a selected lakeside zone, then removed bottom mud is used for reinforcing a lake embankment nearby, an ecological revetment structure is constructed according to 'code for design of levee project', land area plants, emergent aquatic plants, submerged plants and other plants are planted for phytoremediation, meanwhile, wave dissipation protection is set, the plants are protected, and dailymaintenance is kept. Ecological desilting and lakeside restoration are combined, near-shore bottom mud pollution of slope protection is degraded, sludge is disposed nearby, timber pile and natural revetment is implemented, the land area plants are planted to stabilize embankments, the emergent aquatic plants, submerged plants and other plants are planted to reduce pollution, water and soil conservation is carried out, a complete ecological community is formed, and lakeside zones are effectively restored.

Description

technical field [0001] The invention belongs to the technical field of lakeside protection, and relates to an ecological restoration method for steep lakeside belts of polluted lake sediments in shallow water lakes. [0002] technical background [0003] With the development of society, affected by natural and human activities, the structure and ecological process of the lakeside belt are disturbed and destroyed, resulting in the decline of its ecological function and biodiversity and the degradation of natural landscape. The lakeside zone plays an important role in water conservation, flood storage and drought prevention, siltation promotion, land reclamation, water purification, biodiversity maintenance and ecological balance. In the past, the ecological restoration of the lakeshore zone of shallow lakes only focused on selecting areas with heavy water pollution to set up wave-dissipating layers and wave-proof layers to plant aquatic plants such as submerged, emergent, and ...

AI Technical Summary

Problems solved by technology

In the past, the ecological restoration of the lakeshore zone of shallow lakes only focused on selecting areas with heavy water pollution to set up wave-dissipating layers and wave-proof layers to plant aquatic plants such as submerged, emergent, and floating water to build aquatic plant communities (Chinese patent CN101486512), while The removal of near-shore sediment pollution and the reinforcement of the shore slope structure of the lakeside zone are ignored in the restoration of the lakeside zone to build a complete, stable and anti-scouring lakeside zone
