Core Viewpoint - The ecological environment of the Huangyan Island sea area is being systematically assessed, revealing a stable and diverse natural ecosystem that requires ongoing protection and research efforts [1][4]. Group 1: Investigation Characteristics - The 2025 investigation emphasizes three aspects: increased systematization and specificity, scientific rigor and advancement, and integration of multi-source data [2][3]. - Compared to the previous year, the investigation has expanded its focus to include new ecological elements such as seagrass and giant clams, with a 50% increase in coral reef survey points and a sample collection volume that is 2.9 times larger than last year [2][3]. Group 2: Ecological Findings - The investigation found that the environmental quality of the Huangyan Island sea area remains excellent, with water and sediment quality classified as Grade I [3][6]. - Coral reef ecosystems are healthy and stable, with an average coral cover of 29.8%, and a significant increase in coral species recorded compared to 2024 [6][7]. - The biodiversity of the area is rich, with 134 species of reef-building corals and 145 species of reef fish documented, indicating a thriving ecosystem [5][6]. Group 3: Conservation Efforts - China has established a national nature reserve for Huangyan Island, emphasizing strict ecological protection and regulatory enforcement to safeguard the area's biodiversity [12][13]. - Continuous scientific research and monitoring are being conducted to understand the resilience of coral reefs to climate change and to implement targeted conservation measures [11][13].
