Embodiment 1

[0024] (1) Select restoration area and conduct habitat survey:

[0025] A comprehensive understanding of the state of the target wetland before damage, the cause of damage, and the degree of human interference during the restoration process can be made to select the area that needs ecological restoration. The second is to conduct habitat surveys, including comprehensive surveys on the climatic conditions, soil conditions, water resources, vegetation, animal and plant resources of the target wetlands;

[0026] (2) Restoration of sunken and erosive coastal wetlands:

[0027] A. Construction of flood dikes and breaking wave peninsulas: new flood dikes are built to protect the wetlands and supratidal zones in the dikes; according to the local wind direction and speed, the breaking wave peninsulas are arranged, and the breaking wave peninsulas can also protect the flood dikes from erosion and reduce The flow velocity of the tidal current in the wetland promotes the sedimentation a...

Abstract

The invention relates to an ecological restoration method for a damaged seacoast wetland, and belongs to the field of wetland vegetation recovery. The ecological restoration method comprises the following steps: (1) selecting a restoration area to carry out living condition research; (2) restoration of a sinking type erosive seacoast wetland: establishing a flood bank and a broken water peninsula, carrying out dredging mud covering, and establishing a tidal channel and a gentle slope; (3) building a wetland plant community, wherein wet plants comprise aquatic plant and halophilous plant, and sowing and trophosome transplanting combined planting; (4) establishing an ecological isolation belt: planting trees and shrubs and emergent aquatic plant in the peripheral range of 2 to 4 m in the wetland as the ecological isolation belt; (5) scientifically controlling the growth of Spartina alterniflora Loisel: controlling the growth of Spartina alterniflora Loisel via water quantity control, and manpower and machine harvesting and burying. Dredging mud is used for ecological restoration of the damaged seacoast wetland, the erosive seacoast wetland can be reinforced, the sediment is effectively stabilized via the construction of the wetland plant community, a diversified environment is created, and the ecological environment quality of the seacoast wetland is improved.

Description

technical field [0001] The invention belongs to the field of wetland vegetation restoration, and in particular relates to a method for ecological restoration of damaged coastal wetlands. Background technique [0002] As the ecotone of the two systems of sea and land, coastal wetlands have powerful ecological service functions, including water conservation, water supply slowdown, erosion control, back-up land resources, nutrient salt and pollutant decomposition, and habitat for aquatic and marsh organisms. land, breeding areas and migratory birds' wintering grounds, etc. [0003] In recent years, due to the intensification of human activities in the upper reaches of rivers and coastal areas, the sediment content in the estuary area has changed, which directly affects the erosion and deposition environment in the estuary area, resulting in the reduction of estuary wetland area and the degradation of its function. At the same time, with the implementation of nearshore projects...
