Three-stage protective screen ecological wall

Abstract

The invention relates to a three-stage protective screen ecological wall, and relates to the field of ecological environment engineering. The invention mainly adopts a technical scheme that the three-stage protective screen ecological wall comprises a first protective screen, a second protective screen, a third protective screen and a biomimetic wall body, wherein the bottom of the first protective screen is inserted into submarine mud, and the distance from the top of the first protective screen to the perennial low water level of shallow-water rivers and lakes is 10-20cm; the second protective screen comprises potamogeton crispus and water chestnuts; the bottom of the third protective screen is inserted into submarine mud, the top of the third protective screen is 30-50cm lower than the top of the first protective screen, a predetermined distance is reserved between the third protective screen and the first protective screen, and the second protective screen is arranged between the first protective screen and the third protective screen; the biomimetic wall body comprises a plurality of artificial water plants and a plurality of floating beds in predefined specifications; one end of each artificial water plant is connected with the top of the third protective screen, the other end of each artificial water plant is connected with the corresponding floating bed, and a plurality of floating beds float on the water surface. The three-stage protective screen ecological wall disclosed by the invention can reduce stormy waves of rivers and lakes, and can increase the transparency of water bodies at the same time.

Description

technical field [0001] The invention relates to the field of ecological environment engineering, in particular to a three-stage barrier ecological wall. Background technique [0002] At present, with the increasing frequency of human activities, the aquatic ecosystems of some shallow rivers and lakes have been seriously damaged. Specifically, the water transparency of shallow rivers and lakes has decreased, the water body has become severely eutrophic, and algae accumulation on the water surface often occurs, and the oxygen content in the water body is low. The death of aquatic animals due to lack of oxygen. Therefore, improving water environment quality and restoring water ecological health are the main goals of river and lake governance in my country. [0003] In the prior art, water ecology restoration methods such as lake shore restoration and aquatic plant restoration are often used to improve the water quality of shallow rivers and lakes. However, because shallow riv...

Problems solved by technology

However, because shallow rivers and lakes often have large wind and waves, the sediment suspension spreads around, reducing the transparency of the water body; the suspended particles disperse in the water body, which seriously affects the growth of aquatic plants in the lakeside zone, and the lakeside Water ecological restoration such as shore zone restoration and aquatic plant restoration is an important means to improve the water quality of rivers and lakes. However, in the process of carrying out the actual ecological restoration project, due to natural factors such as high wind, waves, and low transparency, the restoration of aquatic plants in the lakeside coastal zone is unsatisfactory.
