Coastal wetland vegetation restoration method

Abstract

The invention discloses a coastal wetland vegetation restoration method. The coastal wetland vegetation restoration method comprises the following steps that 1, an area to be restored is determined, habitat surveying is performed; 2, fences are built around wetland critically degenerated and lightly degenerated for enclosure and livestock reduction; 3, on the basis that an original whole foundation structure of wetland is not destroyed or transformed, local terrain restoration or protection is conducted on regions mediumly degenerated and severely degenerated to achieve wetland habitat building and improvement; 4, restoration of subsided and erosive coastal wetland is performed in the regions mediumly degenerated and severely degenerated; 5, wetland plant communities are built; 6, ecologicisolation belts are built; 7, smooth cordgrass growth is scientifically controlled. Ecological restoration of damaged coastal wetland is performed by using dredged soil, erosive coastal wetland can be reinforced, sediment can be effectively stabilized by building wetland plant communities, a diversified habitat is created, and the ecological environment quality of coastal wetland is improved.

Description

technical field [0001] The invention relates to the technical field of wetland vegetation restoration, in particular to a coastal wetland vegetation restoration method. Background technique [0002] As an ecologically interlaced zone of two major systems of sea and land, coastal wetlands have powerful ecological service functions, including water conservation, water supply mitigation, provision of reserve land resources, nutrient salt storage and pollutant decomposition, as well as habitats for aquatic and marsh organisms, reproduction. areas and migratory wintering grounds for migratory birds. [0003] In recent years, due to the intensification of human activities in coastal areas, the increase in the number of elk populations has caused damage to the habitat, thereby affecting the sustainable supply of elk food. At the same time, with the implementation of coastal projects, especially large-scale reclamation projects, many coastal wetlands have been directly reclaimed, t...

AI Technical Summary

Problems solved by technology

At the same time, with the implementation of nearshore projects, especially large-scale reclamation projects, many coastal wetlands have been directly reclamated, the natural coastline has been continuously reduced, and coastal wetlands have been degraded, affecting the continuity of elk habitats and reducing coastal environmental carrying capacity.

In addition, reclamation and other projects that significantly change the natural attributes of the coast have caused changes in the near-shore hydrodynamic conditions, some local sections of the coast have evolved into eroded sections, and the original coastal wetlands have further degraded
