Ecological bay channel based on permeable dike
The invention discloses an ecological bay channel based on a permeable dike. The ecological bay channel based on the permeable dike comprises the permeable dike (5) arranged between the upstream sideof an ecological island (3) and a river bank (7) of a river channel (1). An accommodating chamber (51) is formed downwards in the middle of the top of the permeable dike (5), and a plurality of artificial biological grids (51a) are arranged inside the accommodating chamber (51). The side wall of the accommodating chamber (51) is a reinforced concrete permeable wall (52), and an ecological floatingbed (55) is arranged at the top of the accommodating chamber (51) in a covering mode. The artificial biological gates (51a) are arranged at the bottom of the ecological floating bed (55) in a hung mode. A bay channel body (2) is separated from a main channel body of the river channel (1) by the permeable dike (5) formed by piling up stone, and the water level of the bay channel body (2) is regulated by controlling the elevation of the top end of the permeable dike (5). During the flood season, flood water overflows to the bay channel body (2) through the top end of the permeable dike (5), andthe flood regulation and storage total amount of the river channel (1) can be increased; and after raining, since water is blocked by the permeable dike (5), the water velocity in the bay channel body (2) is much lower than that in the river channel (1), and a suitable place for aquatic animals to live and breed is provided.

Construction method and application of coastal wetland protection and restoration system
PendingCN110984059APromote water circulationIncrease varietyDamsClimate change adaptationEnvironmental resource managementDry season
The invention discloses a construction method and application of a coastal wetland protection and restoration system. Through micro-slope reconstruction, earth cutting is conducted in shoal water to construct an ecological island to provide a breeding place for summer residents; deep trenches are excavated around the island to provide a shelter for fishes in the dry season; and fresh water supplyand circulation are ensured to create a bird foraging habitat and a sheltered habitat, and thus a bird conservation effect is improved. According to the construction method and application of the coastal wetland protection and restoration system, a principle of using local materials is adopted, local soil is utilized to conduct dam surrounding and island building, and foreign building materials are not introduced, so that disturbance to a local environment due to introduce of the foreign building materials is reduced while the cost is saved, and good practical application value is achieved.
