Core Viewpoint - The Hainan University marine ranch research team has significantly contributed to the ecological restoration of coral reefs in Sanya, enhancing marine biodiversity and attracting tourism to the region [2][3]. Group 1: Coral Reef Restoration Efforts - The Hainan University marine ranch research team has been working on coral reef ecological restoration since 2011, utilizing artificial reef technology and coral transplantation techniques [2][3]. - The team has implemented a three-dimensional restoration model combining artificial reefs, coral nurseries, and ecological monitoring, which has improved coral planting density and simulated natural reef structures [2][3]. - The coral coverage in the Sanya Wuzhizhou Island marine ranch demonstration area has increased from less than 15% to 28.78%, with soft coral coverage rising to 9.6% since the introduction of artificial reefs [3]. Group 2: Research and Technological Innovations - The research team has developed a "coral nursery" vertical planting technology, increasing the survival rate of coral seedlings from 40% to 75% [2]. - A coral reef health assessment model based on drone remote sensing technology has been created, enabling dynamic monitoring of ecological indicators in restoration areas [2]. - Over 1 hectare of coral reef has been artificially restored, with more than 50,000 coral transplants of over 10 species, achieving a survival rate exceeding 90% within one year [3]. Group 3: Biodiversity and Ecological Impact - The nearshore coral coverage at Wuzhizhou Island has surged to 37.08%, with the presence of 116 species of reef-building corals and 265 species of fish, including rare species like dolphins and whale sharks [3]. - The marine ranch has developed a complete ecosystem comprising coral reefs, fish, shrimp, and shellfish, demonstrating significant achievements in marine ecological restoration and fishery resource conservation [3].
