The waters around Sansha City of south China's Hainan Province have seen thriving marine ecosystems, as witnessed by vast stretches of coral reefs, according to a recent ecological survey.
Using underwater observations and transect analysis, the survey team found higher-than-expected coral coverage in several areas of Sansha -- China's southernmost island city.
The waters host a wide variety of species, from hard and soft corals to staghorn, brain and mushroom corals, forming complex, diverse reef structures. Lush and brightly colored, the corals reflect strong ecological health.
In recent years, Sansha has strengthened marine protection, strictly regulated fishing, and reduced human disturbance, creating favorable conditions for coral recovery and growth.
"In some areas, the coral communities are thriving far more than we imagined. For example, south of the airport, we found a massive stretch of reefs, covering hundreds of hectares. The coverage rate here is likely to surpass 80 or even 90 percent," said Yang Qingsong, an engineer at the Xisha Marine Environment National Observation and Research Station in Hainan.
The flourishing coral reef ecosystem has significantly enhanced marine biodiversity in the region. The corals teem with diverse marine life, including tropical fish, shellfish, and starfish, providing them with essential habitats and food sources that sustain the entire marine ecosystem.

Police in Shenzhen City of south China's Guangdong Province have deployed 24-hour drone patrols around the Shenzhen Sports Center to enhance public safety control during the 2026 Chinese Super League season.
The Shenzhen Xinpengcheng Football Club has officially made the Shenzhen Sports Center its home ground for the 2026 Chinese Super League season. Football matches have attracted more than 10,000 fans per match, leading to intense crowd density and severe traffic congestion, which places immense pressure on security.
Amid the excitement of tens of thousands, the calmest "guards" aren't in the stands, but stationed over 100 meters above, in the sky.
Before a match began, police officer Wang Yiyuan and two teammates would be already deployed with well-defined roles: one would pilot the drones, another would keep an eye on the spectrogram to monitor the drone activity, and the third would coordinate with other ground police via his walkie-talkie.
Just before the end of the second half, a sudden alert for crowd flow popped up at the south square, where a large number of spectators had begun to gather as they leave the site. As this area served as the only passage for leaving the stadium, the crowd pressure could easily lead to a stampede.
From the initial alert to the loudspeaker broadcast and then to the arrival of police reenforcements on the scene, it took Wang and his colleagues just three minutes to complete the communication, and the crowds began to disperse.
