    An aerial view of the Xisha Qundao Photo: VCGChina's Ministry of Natural Resources on Friday for the first time released a concentrated assessment of the ecological conditions of islands and reefs in the Xisha, Zhongsha and Nansha Qundao island groups, presenting a detailed picture of nine representative islands and reefs ahead of China's 2026 National Ecology Day, which falls on August 15, China Central Television (CCTV) News reported Friday.
The assessment showed that the nine islands and reefs are generally in good ecological condition, although their ecosystems vary significantly from one location to another. The findings are expected to provide a scientific basis for more targeted conservation and management of different types of island and reef ecosystems.
Coral reef ecosystems in the Xisha Qundao have shown encouraging signs of recovery. The overall ecological conditions of four atolls, including the Beijiao, the Yongle Atoll, Yuzhuo Jiao and Langhua Jiao, of the Xisha Qundao, were rated as good.
Although live coral cover remains relatively low as a result of the large-scale coral bleaching event in 2020 and outbreaks of crown-of-thorns starfish since 2018, the reefs have recorded a high level of hard-coral recruitment, indicating strong and continued recovery, CCTV reported. 
Coral reefs are one of the best natural indicators of seawater quality, and are also a key foundation for marine biodiversity, Chen Xiangmiao, director of the World Navy Research Center at the National Institute for South China Sea Studies, told the Global Times on Friday. 
Huangyan Dao, meanwhile, stands out as a rare "biological gene bank" in the central South China Sea. Surveys recorded 135 species of reef-building corals around Huangyan Dao. Seagrass beds covering about 1.85 square kilometers were found distributed across its lagoon, with an average coverage of 19.2 percent. Live coral cover within the protected area has reached 38.8 percent.
The waters are also home to a range of rare and protected species, including green sea turtles, hawksbill turtles, giant clams and trumpet tritons, according to the assessment.
Chen said Huangyan Dao's coral reef ecosystem provides stable and diverse habitats for a wide range of marine species. With relatively limited development, its coral reefs function much like an underwater forest, offering feeding, shelter and breeding grounds for rare species such as sea turtles and giant clams. Its shallow lagoon and seagrass beds further enrich the variety of habitats, allowing different species to coexist and supporting a high level of biodiversity.
Ecological conditions among the Nansha Islands and reefs showed greater differences. While the overall condition remained good, some individual reef ecosystems have suffered serious degradation, according to CCTV News. 
Xianbin Jiao and Niu'e Jiao were assessed as being in good ecological condition, with live coral coverage reaching 24.7 percent and 37.7 percent, respectively.
By contrast, the ecosystems of Tiexian Jiao and Ren'ai Jiao have deteriorated significantly.
At Tiexian Jiao, outbreaks of crown-of-thorns starfish, tropical cyclones and foreign human activities, particularly continued construction by the Philippines on Zhongye Dao, have contributed to ecological damage. The area covered by live corals has fallen by nearly 70 percent compared with 2016. 
At Ren'ai Jiao, the long-term presence of a foreign military vessel illegally grounded there has caused pollution discharge, waste accumulation and fishing-net entanglement, according to the assessment. Live coral coverage has declined sharply, while both coral growth and natural recovery have been inhibited, according to CCTV. 
China has also continued to increase investment in marine ecological conservation and restoration in the South China Sea.
According to one of the released reports on ecological protection and restoration, natural resources, marine and forestry authorities at various levels in the South China Sea region implemented 66 marine ecological restoration projects in 2025, with total investment approaching 5 billion yuan ($741.5 million). 
China has long made the protection of the South China Sea's marine environment a priority, with particular attention to coral reefs, fishery resources and water quality, Chen said, adding that the good ecological conditions found at these islands under China's management show that conservation and restoration efforts have produced tangible results. 
During the 14th Five-Year Plan period (2021-25), a total of 262 marine ecological protection and restoration projects were carried out, involving more than 21.3 billion yuan in investment.
By the end of 2025, approximately 2.66 million hectares of marine ecological conservation redline areas and about 7 million hectares of marine nature reserves had been designated in the South China Sea region.

B |     处暑的“处”字是终止的意思，表示炎热日消，暑气渐退。

C | 《月令七十二集解》中记载：“处暑，七月中。处，止也。

D | 暑气至此而止矣。”古人将处暑分为三候。一候“鹰乃祭鸟”，古人称鹰为义禽，秋气肃杀，鹰感其气而开始大量捕猎鸟类，并把猎物整齐摆放仿佛祭祀。

E | 二候“天地始肃”，天地间万物开始凋零，充满了肃杀之气。三候“禾乃登”，禾是黍、稷、稻、粱等农作物的总称，“登”引申为谷物成熟。

F | 处暑过后，田野里可见“谷到处暑黄”的秋收景象。

G | 我国大部分地区昼夜温差增大的天气条件，对农作物体内干物质的制造和积累十分有利，庄稼成熟较快，因而民间有“处暑禾田连夜变”之说。

H | “处暑”的到来意味着炎热的夏天逐步向凉秋转换，昼夜温差增大，民间有处暑吃鸭子的习俗，认为农历七月中旬的鸭子最为肥美营养，能补阴益血、清热健脾。“离离暑云散，袅袅凉风起”，白居易的这句诗描绘的就是处暑时节暑气消散、凉风徐来的早秋情景。不过，这是对北方地区而言。对于杭州来说，秋天还早呢。杭州常年平均入秋时间为10月3日。最晚入秋时间是10月23日，出现在2006年。

I | 虽然最近几天因为东风气流和雨水的影响，杭州的最高气温都不算高，没有超过35℃高温线，但随着副热带高压的增强，明天天气转好，这雨一停，说不定马上就又是高温天。处暑到了，明天出伏。少儿公园的桂花已经零星开放，黄山栾也开花了，有细心的橙友发现银杏果也黄了，秋天的信号正在不经意间释放，可以开始期盼“一场秋雨一场凉”以及美好的秋天了。
