Core Insights - The ecological environment of the Huangyan Island sea area is reported to be continuously excellent, with water quality and marine sediment quality maintaining a first-class rating, and pollutant residues in fish samples below evaluation standards [1][2] Group 1: Environmental Quality Assessment - The report indicates that the Huangyan Island sea area has a stable and healthy coral reef ecosystem, with 134 species of reef-building corals recorded, an increase of 25 species compared to 2024 [2] - The average coverage of live corals is reported at 29.8%, with a high replenishment rate of coral juveniles, demonstrating good resistance and tolerance to rising sea temperatures [2] - The biodiversity of reef-associated organisms is rich, with 145 species of reef fish recorded, an increase of 20 species from the previous survey [2] Group 2: Ecological Risks and Pressures - Despite the positive assessment, the report highlights that the coral reefs face increasing thermal stress due to climate change, and the potential risk of coral bleaching should not be overlooked [2] - The natural ecosystem's diversity, stability, and sustainability are deemed beneficial for marine life in the South China Sea, serving as an important habitat and refuge [2]

Core Insights - The report titled "2025 Ecological Environment Status Assessment of Huangyan Island Waters" indicates that the environmental quality of Huangyan Island waters remains excellent, with water quality and marine sediment quality classified as first-class [1][2] Group 1: Environmental Quality - The assessment shows that heavy metals and petroleum hydrocarbons in fish samples are below evaluation standard limits, and cyanide was not detected in water, sediment, or fish samples [1] - The average coverage of live coral is reported at 29.8%, with a high replenishment rate of coral juveniles, indicating resilience to rising sea temperatures [2] Group 2: Coral Reef Ecosystem - The coral reef ecosystem is healthy and stable, with 134 species of reef-building corals recorded, an increase of 25 species compared to the 2024 survey [2] - Biodiversity is rich, with 145 species of reef fish recorded, an increase of 20 species from the previous year, and no signs of coral disease or significant predatory species [2] Group 3: Ecological Significance and Risks - Huangyan Island's natural ecosystem is noted for its diversity, stability, and sustainability, providing crucial habitats for marine life and serving as an important indicator of global climate change and environmental evolution [2] - However, the report warns that the coral reefs face increasing thermal stress due to climate change, and the potential risk of coral bleaching should not be overlooked [2]
