Coastal constructed wetland ecological maintenance system and ecological maintenance method

Abstract

The invention discloses a coastal constructed wetland ecological maintenance system and an ecological maintenance method. The system comprises a fish and shrimp ecological planting and breeding area, an artemia breeding and culture area and a bromine extraction and salt production area, the side surface of the fish and shrimp ecological planting and breeding area is provided with a water inlet channel for introducing seawater or brackish water into the fish and shrimp ecological planting and breeding area; a sedimentation and biological purification channel is arranged between the fish and shrimp ecological planting and breeding area and the artemia breeding and culture area and used for conveying organic high-concentration saline water containing fish and shrimp excrement in the fish and shrimp ecological planting and breeding area to the artemia breeding and culture area; a drainage channel is arranged between the artemia breeding and culture area and the bromine extraction and salt production area and is used for conveying high brine formed by evaporating the artemia breeding and culture area for a long time to the bromine extraction and salt production area; and waterfowl habitat islands are built in the fish and shrimp ecological planting and breeding area and the artemia breeding and culture area. According to the system and the method disclosed by the invention, wetland water system and food chain double-circulation ecological maintenance can be realized, so that abundant and safe wetland attributes and biological chains are guaranteed.

Description

technical field [0001] The invention relates to the field of wetland ecology, in particular to a coastal artificial wetland ecological maintenance system and an ecological maintenance method. Background technique [0002] Wetlands are located in the transition zone between terrestrial ecosystems and aquatic ecosystems, and are ecosystem types with extremely high biological productivity and rich biodiversity on the earth. According to the Ramsar Convention, wetlands are areas of marsh, peatland, water, natural or artificial, permanent or temporary, with bodies of water that are static or flowing, fresh or brackish and salt, including at low tide The sea area with a water depth of no more than 6 meters has huge ecological benefits and environmental functions, and is known as the "kidney of the earth". [0003] Wetlands are also breeding habitats for birds and a variety of wild animals. They contain rich biodiversity and water resources. They play an irreplaceable role in prot...

AI Technical Summary

Problems solved by technology

However, as water sources are cut off or blindly retreated, high-salt water and brackish water wetlands face no water supply and a sharp decline in the biological chain, which eventually leads to salinization, no aquatic plants, no fish and shrimp, and no birds migrating in the past
