Ecological Impact - The restoration has led to significant improvements in marine biodiversity, with the number of benthic species increasing from 60 to 111, an 85% increase [7]. - The water quality in the area has stabilized at Class II or above, indicating a healthier marine environment [7]. National Policies and Support - Marine ecological restoration, including seagrass bed protection, is included in national plans such as the "14th Five-Year Plan for Marine Ecological Protection and Restoration" [7]. - Central government funding has supported major projects, including the restoration of 1,180 hectares of seagrass beds since the start of the "14th Five-Year Plan" [7]. Broader Marine Ecosystem Initiatives - The article also discusses the restoration of mangroves and coral reefs, which are critical marine ecosystems alongside seagrass beds [9]. - In Hainan, efforts to restore mangroves have led to significant ecological improvements and economic benefits for local communities through eco-tourism [13][14].
