6686ÌåÓýAPP

By CCCC, the Lingang Shanghai Lingang Ecological Restoration Project not only rebuilds the coastal ecological barrier but also stands as a model for intelligent restoration in support of China's national blue carbon strategy.

The project restores 17.05 kilometers of shoreline, including the re6686ÌåÓýAPP of wave-dissipating dikes that reduce wave energy by 70% and can withstand direct impact from Category 14 typhoons. In parallel, a 1,167-meter-long ecological management walkway has been constructed, working in tandem with the dikes to form a solid tidal and shoreline defense line, while also providing a safe habitat for the reproduction of benthic organisms.

The project pioneered the use of oyster reefs and artificial wetlands to combat coastal erosion. Oyster shells were used to construct honeycomb-shaped reef structures, forming an ¡°eco-fortress¡± that buffers wave impact, stabilizes the shoreline, and delivers integrated benefits¡ªbeach protection, wave mitigation, flood prevention, and ecological resilience.

The wetlands act like natural sponge pools, capable of capturing around 5,200 cubic meters of suspended sediment annually. Additionally, the release of 17 tons of marine "eco-cleaners"¡ªsuch as polychaetes and clams¡ªfurther enhances the tidal flat¡¯s self-purification capacity.

The project team employed multiple strategies to control the spread of Spartina alterniflora, an invasive species known as an ¡°ecological killer,¡± while restoring approximately 160 hectares of native salt marsh vegetation such as reeds. Two new benthic species were introduced to the coastal zone, providing abundant feeding grounds for migratory birds and attracting species like the white crane back to the area. As a result, the structure of the coastal wetland ecosystem has been significantly enhanced.

What was once barren tidal flat has now been transformed into a vibrant blue-green habitat teeming with life, emerging as a new driving force for the blue carbon ecosystem along Shanghai¡¯s coast.
