A slit coastal wetland and a restoration method thereof are disclosed. The slit coastal wetland comprises a coastline, an ecological conservation area structure, an ecological dam and an artificial water system. The ecological dam is connected with one side of the coastline. The ecological conservation area structure is arranged between the coastline and the ecological dam. The artificial water system is connected with the interior of the ecological conservation area structure, and passes through the ecological dam to be communicated with the outer side of the ecological dam. The ecological conservation area structure comprises an ecological conservation area, a planting base and a two-way water gate. Compared with the prior art, the slit coastal wetland and the restoration method thereofhave the advantages that artificial intervention is combined with natural succession, the planting base is formed through slit blow filling and reinforcing, rapid growth of vegetation is promoted in an early stage of growth of the wetland vegetation through the moisture and wave resistance effect of the ecological dam and through water exchange between the water gate and the artificial water system in tide rising and falling stages, seawater tides are introduced through dam breakage after the vegetation is matured, a tidal flat wetland capable of naturally growing and developing is formed, a diversified habitat is provided for wetland organisms, and restoration of the slit coastal wetland can be achieved rapidly at a low cost.
Description
technical field [0001] The invention relates to the fields of marine environment protection and ecological engineering, in particular to a muddy coastal wetland and a restoration method thereof. Background technique [0002] With the increase of coastal development and utilization and reclamation projects, the area of coastal wetlands has decreased sharply, and the ecological functions have degraded. It is necessary to restore coastal wetlands. At present, coastal wetland restoration technologies mainly adopt technologies such as artificial sedimentation promotion, pond digging, landform shaping, and planting vegetation. These technologies are not systematic and have poor adaptability. 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 are planted and conserved. After the vegetation matures, the culvert p...
