Shanghai Fengxian coastal marine ecological protection and restoration project will be completed by the end of 2024.

　　On the morning of June 30th, Shanghai Fengxian coastal marine ecological protection and restoration project started smoothly. This project is another marine ecological protection and restoration project supported by the central government in Shanghai after the implementation of the coastal marine ecological protection and restoration project in Shanghai in 2022, and will be completed by the end of 2024.

　　The Paper learned from the Shanghai Water Affairs Bureau that the project starts from China and Hong Kong in Fengxian District in the east and reaches Huadian Ash Dam in the west, and the layout of the project is "one corridor and three districts". "One Corridor" refers to building a 17.4-kilometer coastal ecological corridor, relying on coastal ecological restoration, forming land-sea linkage and creating an open strip-shaped coastal composite ecological space; "Three areas" refers to the construction of multiple ecological service function integration area, middle and high beach habitat protection demonstration area and natural succession habitat area along the coastline from east to west, giving full play to the ecological service functions of each area, creating a bright spot for the restoration of coastal wetlands in Shanghai, and continuously improving the diversity and stability of coastal ecosystems.

　　It is understood that the main project indicators include 51.97 hectares of Spartina alterniflora ecological control, 4,115 meters of tidal ditch system restoration, 69 hectares of native salt marsh vegetation restoration and 6,438 meters of wave dam restoration; A total of 45 hectares of reef habitats have been built, and the ecological transformation of seawalls is 4.5 kilometers; A new coastal ecological monitoring and research station will be built, three ecosystem buoys will be deployed, a carbon flux tower will be built, ecological environment tracking and monitoring will be carried out, and supporting facilities such as popular science signs and scientific research stations will be arranged.

　　"The ecological control project of Spartina alterniflora can solve the ecological problem of serious invasion of Spartina alterniflora in the project area, and the restoration of salt marsh vegetation communities such as reeds and sea bream can further improve the habitat quality of salt marsh wetlands." Yang Dongyan, the second bid construction unit of Shanghai Fengxian Coastal Marine Ecological Protection and Restoration Project and Fengxian Project Manager of China Communications Shanghai Airlines Co., Ltd., said that the coastal zone is an important support for the green development of the city and an important barrier against natural disasters such as storm surges at sea. It plays multiple functions in biodiversity protection, shore protection and beach protection, carbon sequestration and foreign exchange enhancement.

　　At the same time, the ecological problems of serious beach erosion and low health of marine biological community in the project area are solved by implementing the in-situ restoration of wave dam and the construction project of reef habitat with both ecological function and disaster reduction function. By carrying out the ecological reconstruction project of seawall, the ecological problems of blocked habitat connection inside and outside the seawall and poor land-sea coordination in the project area are solved.
