Suggestions for Ecological Restoration of Seagrass Under the Background of Sinicized NbS

Nature-based solutions (NbS) is the concept advocated by the International Union for Conservation of Nature (IUCN), based on China’s unique ecological protection and restoration traditions, natural geospatial patterns, and natural resource features. The development of Chinese NbS solutions will contribute to the implementation of the concept of NbS in China. China has a tradition of afforestation and grassland protection, and the successful experiences are the embodiment of NbS. Therefore, the research on the highlights of ecological restoration of “forest” and “grass” has important inspiration and reference significance for the ecological restoration of seagrass beds. Through the comparison of domestic and foreign research results and case study data, the logical system diagram of countermeasures and suggestions is drawn to improve the correlation and rationality of each recommendation. This paper summarizes the highlights of mangrove and grassland ecological restoration, and points out that there are disadvantages in domestic seagrass bed ecological restoration in terms of policy and public participation, capital investment and technical means, but there are also advantages in the utilization of subtidal space resources and carbon sink under the condition of the seagrass fast growth rate and no change in the nature of tidal flats. The paper puts forward 15 suggestions for promoting the ecological restoration of seagrass beds in China: carry out seagrass bed online monitoring and survey of suitable seagrass places, strengthen the publicity of NbS and seagrass beds, strengthen supervision and law enforcement and coordination, establish reasonable reward and subsidy policies, establish Chinese seagrass professional societies and non-governmental organizations, facilitate public participation, try experiment of climate change adaptation, etc.
