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.

原标题:珠江流域优化水资源调配日前,环北部湾广东水资源配置工程正式开工建设。

B | 这标志着广东省历史上引水流量最大、输水线路最长、建设条件最复杂、总投资最高的跨流域引调水工程进入实施阶段。

C | 水利部部长李国英表示,工程建成后,将进一步优化环北部湾城市群水资源配置格局,从根本上解决粤西地区水资源短缺问题,提升区域供水安全保障能力,对支撑粤西地区经济社会发展具有十分重要的意义。

D | 广东降水丰沛,为何还会缺水?水利部珠江水利委员会副主任易越涛介绍,粤西地区特别是雷州半岛,自古以来就以干旱闻名,沿海诸河多为中小河流,自然调蓄能力弱,丰枯变化大,工程性缺水问题突出。

E | 由于地表水匮乏,导致当地工农业过度开采地下水,又造成了地面沉降等问题。

F | 水资源也因此成为影响区域发展的限制因素。建设重大引调水工程,势在必行。2013年,珠江流域综合规划获国务院批复。“环北工程建成后,可长远解决粤西地区水资源承载能力与经济发展布局不匹配问题,大幅提高区域供水安全保障能力。”水利部规划计划司副司长乔建华介绍,环北部湾广东水资源配置工程总投资606亿元,是国务院确定的今年加快推进的55项重大水利工程之一。

G | 工程从西江干流取水,通过泵站加压提水,穿过云开大山,调水至雷州半岛,输水线路约500公里,覆盖人口超1800万人。据介绍,环北部湾广东水资源配置工程主要为城乡生活和工业生产供水,兼顾农业灌溉,同时也将为改善水生态环境创造条件。“工程建成后,受水区增供水量20.79亿立方米,其中,城乡生活和工业供水14.38亿立方米,农业灌溉供水6.41亿立方米。”易越涛说。此外,工程建成后可退减超采地下水5.66亿立方米,退还被挤占的生态环境用水1.85亿立方米。从西江到粤西,既有连绵的云开大山,又有平缓的滨海平原,既要连通10座水库,又要跨越诸多中小河流,其中不乏行业性甚至世界级技术难题。“针对设计、建设、运维各阶段的重点难点,我们依靠科技创新,聚焦重大技术难题科研攻关,充分论证,编制了《环北部湾广东水资源配置工程科研纲要》。”环北工程项目设计总工程师刘元勋说。珠江流域,水网密布。多年来,各项珠江治理工作不断推进。目前,流域累计建成江海堤防2.7万多公里、各类水库1.7万多座、各类蓄水工程14万多座,流域整体防洪能力有了显著提高,水资源配置和城乡供水体系基本完善。“作为国家水网的重要组成部分,环北部湾广东水资源配置工程的建成将进一步完善珠江流域水资源调配格局。

H | ”易越涛说,接下来,将接续全力做好环北部湾广东水资源配置工程各项工作,不断完善珠江流域水网,为粤港澳大湾区高质量发展提供有力的水安全保障。
