Method for repairing water ecosystem and stepped restoration system of water ecosystem

Abstract

The invention provides a method for repairing a water body ecosystem, and the method comprises the following steps: 1) adding a water body substrate improver into a raw water body, planting aquatic vegetation after the water quality becomes clear, improving the light compensation condition of the water body, and constructing an underwater forest system; 2) constructing ecological interception systems on two sides of the water body to reduce suspended solids in the water body and maintain water quality; and 3) constructing a surface runoff buffer area at the periphery of the ecological interception system to prevent the instability of a side slope caused by wind and rain and prevent turbid water from polluting the water body after water and soil loss. Through the method, the stepped restoration system of the water ecological system is formed; the concentration of suspended matters in the water body can be effectively reduced through the water ecological interception system, the transparency of the water body is greatly improved, a good environment for aquatic plant growth is provided for the water body, then submerged plants are planted to form an underwater forest system, aesthetics and hydrophilicity are considered, and good demonstration and education effects are achieved.

Description

technical field [0001] The invention relates to the technical field of water body ecological restoration, in particular to a method for restoring a water body ecosystem and a cascaded water ecosystem restoration system. Background technique [0002] Domestic research has paid more attention to social hot issues such as lake eutrophication and black and odorous water bodies. With the financial and technological investment of the state and local governments, the problems of black and odorous water bodies and lake eutrophication have been greatly alleviated, but this does not mean that my country Most water bodies in China have complete ecosystems. On the contrary, most of the water bodies in our country are in a sub-health state, that is, facing the problem of blue-green algae outbreak or eutrophication at any time. Once stimulated by the outside world, the water body in this sub-health state will be completely polluted, and water safety problems will break out. , this sub-hea...

Problems solved by technology

However, the above methods have shortcomings such as narrow consideration, dead angles, and lack of systematization and aesthetics, which seriously restrict the monitoring and treatment of water ecological non-point source pollution.
