Discussion on the Main Technologies and Problems of the Restoration of Typical Coastal Ecosystems in China
The restoration of coastal ecosystems is an important part of China's marine ecological protection work.Numerous marine ecological restoration projects have been approved and implemented throughout the country,resulting in higher requirements for research on marine ecological restoration technologies.Starting from the mode division of typical coastal ecosystem restoration,this article summarizes the common restoration technologies for typical ecological types such as coastal salt marsh wetlands,tidal flats,seagrass beds,mangroves,coral reefs,and oyster reefs;Briefly introduced The technical bottlenecks of various restoration techniques;The current practical problems in the current marine ecological restoration in China were pointed out,including insufficient theoretical research on coastal ecosystem restoration,mainly relying on artificial restoration methods,insufficient emphasis on ecosystem function restoration,and a lack of connectivity and continuity in the spatiotemporal scale of restoration effects.The current practical problems in the current marine ecological restoration in China were pointed out,including insufficient theoretical research on coastal ecosystem restoration,mainly relying on artificial restoration methods,insufficient emphasis on ecosystem function restoration,and a lack of connectivity and continuity in the spatiotemporal scale of restoration effects.Several key technical issues that urgently need to be solved have been proposed,such as the breakthrough of efficient and low-cost seagrass bed restoration key technology,the development of coral reef restoration key technology,and the need to improve the selection of suitable forest land for mangrove forests and the technology of returning ponds to forests;And it is proposed that in the future,the top-level planning of ecological restoration should be taken as the guide to further strengthen relevant research.
