A tidal flat wetland at the front of a seawall and its restoration method, comprising: a seawall, an ecological conservation area structure, a siltation-promoting dam and a tidal channel, the seawall is arranged on one side of the siltation-promoting dam, and the ecological conservation area structure is arranged on the seawall and the siltation-promoting dam In the middle of the dam, the tidal channel is set in the middle of the dam. Among them, the structure of ecological conservation area includes: ecological conservation area, planting base, ecological dam and two-way water gate. Compared with the traditional technology, the present invention forms the base through artificial silt-promoting and dredging filling methods, and promotes the rapid growth of vegetation through the anti-tide and wave-resisting effect of the ecological dam and the water exchange during the ebb and flow of the water gate in the early stage of wetland vegetation growth. After maturity, break the embankment and introduce the sea tide to form a tidal flat wetland that can grow naturally, provide a variety of habitats for wetland organisms, and quickly restore coastal tidal wetlands at a low cost. It is suitable for the restoration of tidal flat wetlands at the front of seawalls.
Description
technical field [0001] The invention relates to the fields of marine environment protection and ecological engineering, in particular to a tidal flat wetland at the front of a seawall and a restoration method thereof. Background technique [0002] With the increase of coastal development and utilization and reclamation projects, the area of coastal tidal wetlands has decreased sharply, and a large number of artificial seawalls have been formed, degrading ecological functions, and it is necessary to restore tidal flats and wetlands outside the existing seawalls. At present, coastal wetland restoration technologies mainly adopt technologies such as artificial siltation promotion, pond digging and soil piling, terrain rectification, and vegetation planting. For example, Patent Publication No. CN105638015 builds an ecological dam on the outer edge of the restoration area. In the restoration area, ponds are dug and piling up soil to form a plant growth area, and wetland plants ...
