Abstract

A silty coastal wetland and a restoration method thereof, comprising: a coastline, an ecological conservation area structure, an ecological dam and an artificial water system, the ecological dam is connected to one side of the coastline, the ecological conservation area structure is set between the coastline and the ecological dam, the artificial water system and the ecological The conservation area structure is internally connected, and the artificial water system passes through the ecological dam and communicates with the outside of the ecological dam. Among them, the structure of ecological conservation area includes: ecological conservation area, planting base and two-way water gate. Compared with the traditional technology, the invention utilizes the combination of artificial intervention and natural succession, forms the base by filling the silt and reinforces it, and realizes the fluctuation through the damp-proof and wave-blocking effect of the ecological dam, the water gate and the artificial water system in the early stage of wetland vegetation growth. The water exchange during the tidal period promotes the rapid growth of vegetation. After the vegetation matures, the embankment is broken and the sea water current is introduced to form a tidal flat wetland that can grow and develop naturally. recover.

Description

technical field [0001] The invention relates to the fields of marine environmental protection and ecological engineering, in particular to a muddy coastal wetland and a restoration method thereof. Background technique [0002] With the increase in the development and utilization of coastal zones and reclamation projects, the area of ​​coastal tidal flat wetlands has decreased sharply, and the ecological functions have been degraded. It is necessary to restore coastal tidal flat wetlands. At present, the coastal wetland restoration technology mainly adopts artificial silting, digging pond and soil, terrain shaping, planting vegetation and other technologies. 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, digs ponds and piles up soil in the restoration area to form a plant growth area, grows wetland plants and conserves them. After the vegetati...
