This invention relates to a method for constructing a biodegradable mangrove ecological island based on dynamic tidal energy regulation, and an artificial island siltation device. The artificial island siltation device includes a bamboo gate system, a hemp rope net system, a fixed pile system, and a limiting system. A dynamic filtration structure is formed by the liftable bamboo gate and the hemp rope net. Utilizing the buoyancy difference and water flow velocity changes generated by tidal rise and fall, a synergistic effect is achieved: accelerating the passage of sediment-laden water during high tide and promoting siltation during low tide. A fully biodegradable material is used to construct a growing silt body. The buoyancy balance is regulated by the bamboo joint holes, ensuring the device remains suspended on the surface layer of the silt body. This allows for continuous siltation and elevation of the tidal flat, forming an artificial island that provides a site for mangrove seedling planting and meets the required daily sunrise duration for mangrove growth. The method and device of this invention have technical advantages such as low construction cost, dynamic adaptation to tidal changes, and avoidance of secondary pollution.

The present application relates to a kind of ecological island building fill unit, fill unit middle is provided with through hole, fill unit includes shell surface layer, middle structural layer and internal filling layer;Shell surface layer is made of neutral material, to ensure that the sea bottom water quality and related environmental indicators where fill unit is after sinking to bottom are not affected;Structural layer uses high-performance corrosion-resistant material, for bearing the water head pressure after fill unit sinking to bottom, unit stacking transmission pressure and mutual collision force, the whole outside of structural layer is covered by shell surface layer, and internal full-closed cavity is formed;Filling layer uses the full-closed cavity surrounded by structural layer, and fills crushed construction waste.The present application has the advantages of simple structure, large specific weight, easy production and transportation, etc.

This invention relates to an ecological island construction method for land reclamation, comprising, from bottom to top, a reef base layer, a perforated rockfill layer, an island surface leveling layer, and a subsequently constructed concrete island surface. The reef base layer is laid on the reef bottom and is composed of artificial pebbles dumped into the sea. The perforated rockfill layer is laid on top of the reef base layer and is formed by the natural sinking and accumulation of reclamation units. The reclamation units are artificial pebbles with through holes in the center. The island surface leveling layer is laid on top of the perforated rockfill layer and is composed of artificial pebbles bonded together with concrete adhesive, filling the gaps in the lower perforated rockfill layer and providing a sealed space for the subsequent concrete island surface pouring. The subsequent concrete island surface is constructed by pouring concrete onto the surface of the island surface leveling layer, allowing it to penetrate the lower island surface leveling layer, mix with the graded artificial pebbles within the layer, and solidify to form a reclaimed island surface that can be exposed above the sea surface. This invention combines load-bearing and ecological functions, reducing the damage to the nearshore reef ecosystem caused by sand blowing, while also improving the flexibility of land reclamation construction.

The invention discloses a river channel ecological restoration method based on construction of an ecological island, and the method comprises the following steps: S1, bank protection pile foundation construction: after the bank protection pile foundation is completed, ecological island planting piles are constructed; s2, pile foundation construction of ecological island planting piles is conducted according to the construction drawing; s3, pile foundation construction of ecological island planting piles is completed through piling equipment; s4, steel pipe piles are installed around the ecological island planting piles, and then earthwork backfilling is conducted in the ecological island planting piles; the construction of the ecological island is completed; s5, after the ecological island is constructed, plants in the island are planted, and construction of the ecological island is completed; s6, river dredging and water quality adjustment are conducted, and river bottom sludge is cleaned through a pontoon; and S7, ecological soft enclosure construction is carried out, water quality adjustment treatment is carried out through an ecological soft enclosure, and river ecological restoration is completed. According to the method, by building the ecological island and arranging the ecological soft enclosure, the pollution load of the water body is rapidly reduced, a healthy aquatic ecological sequence is rebuilt, and the water body remediation speed is increased.

The application discloses a kind of progressive gain type repair city riverway's device's repair method, it includes floating garbage collection device, artificial ecological island and ecological blanket, artificial ecological island includes the base being located at riverway bottom, different particle sizes of stone are sequentially arranged in base along the river direction, water purification plant is planted on base, gas collected in the collecting chamber of the bottom of ecological blanket is connected with one end of gas guide pipe, the other end of gas guide pipe is stretched into below floating garbage collection device;The application realizes three-dimensional repair process, the uppermost layer is intercepted and collected by floating garbage collection device and the garbage floating on the water surface, the upper layer of water body is treated by artificial ecological island in the particulate pollutants in water body, the lower layer of water body and the area close to the bottom mud of riverway bottom are repaired by ecological blanket water body, and the methane generated by the bottom mud of riverway bottom is collected, is introduced below floating garbage collection device by gas guide pipe, the bubble formed drives the particulate pollutants mixed in water body to float upwards, prevent it from depositing in riverway bottom.

This invention relates to a method for constructing a near-natural vegetation landscape for urban wetland ecological islands. The city in question is located in the Yangtze River Delta region. The method includes the following steps: Step S1: Selecting several plant communities in the target area and its surrounding areas, and evaluating their naturalness using a modified AHP-entropy weight method, to obtain a reference native plant community suitable for constructing a near-natural vegetation landscape for the urban wetland ecological island; Step S2: Setting up several square sample grids within each reference native plant community, and identifying the climax pioneer species, successional sequence species, and successional climax species within each sample grid; Step S3: Using a heterospecific-heterogeneous diameter-class-simultaneous stratified mixed planting method, planting the climax pioneer species, successional sequence species, and successional climax species in the target area. This invention's vegetation landscape construction method is objective and scientific, has high ecological benefits, a rapid succession process, and low construction costs.
