Problems solved by technology

[0004] The purpose of the present invention is to provide a method for ecological restoration of nearshore waters, which not only improves the water quality of the water body, but also removes the organic sludge deposited on the bottom of the water, and forms a dynamic balance with the continuous input of pollution sources, fundamentally solving the eutrophication of the water body problem, but also solve the secondary pollution problem of river and lake dredging

Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0035] A method for ecological restoration of nearshore waters disclosed in this embodiment, such as figure 1 shown, including the following steps:

[0036] 1) As a plant growing in water, its role is very important;

[0037] A. Select submerged plants: a. Purify water quality. The root system and the entire leaf surface directly absorb the nutrients in the water body and silt, and the oxygen produced directly produces a huge purification power for the entire water body from bottom to top;

[0038] b. Physical effect. Vegetation can slow down the wind and waves, which is beneficial to maintain the stability of the small particle substrate, increase the deposition of debris, and improve the transparency of the water body;

[0039] c. Protecting organisms, by effectively increasing the space ecological niche, inhibiting biological and abiotic suspended matter...

Abstract

The invention discloses a nearshore water area ecological restoration method, belongs to the technical field of ecological restoration and solves the problems that an ecological restoration method which is adopted at present cures the symptoms but not the disease and a chemical method causes secondary pollution. The nearshore water area ecological restoration method is characterized by comprisingthe following steps: 1) selecting submerged plants which mainly include hydrilla varticillata, hornwort, myriophyllum spicatum and eel grass; 2) delimiting a restoration range in the water area, arranging a solid floater type PVC (polyvinyl chloride) oil containment boom on the periphery of a delimited range, and arranging a fishing net connected with the solid floater type PVC oil containment boom in the delimited water area; 3) planting the submerged plants, wherein the submerged plants are all planted in a range surrounded by the solid floater type PVC oil containment boom and above the fishing net; 4) planting the selected submerged plants. The invention discloses the nearshore water area ecological restoration method which can fundamentally solve the problem of water body eutrophication and simultaneously solves the secondary pollution problem of riverway and lake dredging.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to an ecological restoration method for coastal waters. Background technique [0002] The ecological pollution and textile situation of degraded lakes in my country are not optimistic. The eutrophication of the water body, a large amount of nitrogen, phosphorus and other nutrients flow into the lakes and river mouths, causing algae and other plankton to multiply rapidly, the dissolved oxygen in the water body decreases, and the water quality deteriorates. , a large number of fish and other organisms died, forming algal blooms, resulting in serious degradation of the lake. [0003] With the enhancement of environmental awareness, ecological concept and the improvement of living standards, the requirement to restore the degraded lake ecosystem is becoming more and more urgent. Currently, there are two ecological restoration schemes: one is the physical method, that is, ...
