Ecological conservation system and method for artificial coastal wetland

An ecological conservation method for an artificial coastal wetland, comprising:

• providing a fish and shrimp ecological breeding area, an artemia breeding area and a bromine extraction and salt production area;
• providing a water inlet channel, for introducing seawater or brackish water into the fish and shrimp ecological breeding, arranged on a side of the fish and shrimp ecological breeding area and is used area;
• providing a sedimentation and biological purification channel, for conveying organic high-concentration saline water containing fish and shrimp excreta in the fish and shrimp ecological breeding area to the artemia breeding area, arranged between the fish and shrimp ecological breeding area and the artemia breeding area;
• providing a drainage channel, for conveying high-concentration brine formed by long-time evaporation in the artemia breeding area to the bromine extraction and salt production area, arranged between the artemia breeding area and the bromine extraction and salt production area;
• and
• providing a waterfowl habitat island in the fish and shrimp ecological breeding area and the artemia breeding area
• carrying out ecological culture and proliferation, maintenance and biomass regulation on fish and shrimp in the fish and shrimp ecological breeding area;
• carrying out culture and proliferation, maintenance and biomass regulation on artemia in an artemia breeding area, and feeding caught artemia to the fish and the shrimp in the fish and shrimp ecological breeding area;
• conveying high-concentration saline water carrying organic matter particles in the fish and shrimp ecological breeding area to the artemia breeding area by means of a sedimentation and biological purification channel to be utilized and consumed by the artemia;
• maintaining a water source guarantee of each functional area in the system, connecting the functional areas and injecting and draining water of the functional areas by the water inlet channel and the drainage channel;
• providing, by the waterfowl habitat island, a habitat for a migratory waterfowl, and feeding the fish and the shrimp in the fish and shrimp ecological breeding area and the artemia in the artemia breeding area to the bird;
• and
• making high-concentration brine generated by long-time evaporation in the artemia breeding area enter the bromine extraction and salt production area for bromine extraction and salt production.
