The title slide features "海底热带雨林" (Underwater Tropical Rainforest) as its main text. The subtitle introduces an exploration of the Sanya Coral Reef National Nature Reserve, guardian of the South China Sea coast's ecological treasure.

海底热带雨林

三亚珊瑚礁国家级自然保护区探秘 守护南海之滨的生态瑰宝},

This slide presents basic information on a coral reef ecosystem protected area, China's first national-level coral reef reserve. Established by Hainan Province in 1989 and upgraded in 1990, it covers about 85 km² (55 km² marine, 30 km² land) in the offshore waters at Hainan Island's southernmost tip.

Coral reefs are presented as a core resource, with reef-building corals—animal "architects" like staghorn, brain, and willow types—likened to an "underwater tropical rainforest." They provide habitat for over 400 fish species and feature key organisms such as zooxanthellae and giant clams.

核心资源：珊瑚礁生态系统

• 造礁珊瑚：动物，“建筑师”
• 常见类型：鹿角、脑、柳珊瑚
• “海底热带雨林”
• 栖息地：400余种鱼类
• 关键物种：虫黄藻、砗磲

This slide outlines the core functions and value of marine ecosystems, including coastal protection via wave reduction, supporting nearly 30% of ocean fish breeding, and contributing to the global carbon cycle. It also highlights their role in Sanya's diving tourism and research, plus forming unique tropical marine cultural landscapes.

核心功能与价值

• 海岸防护：消波减浪，保护海岸线
• 生命摇篮：支撑近30%海洋鱼类繁育
• 碳汇功能：参与全球碳循环
• 旅游与科研：三亚潜水旅游与科研基础
• 海洋文化：构成独特热带海洋景观

The slide's left column lists main threats to coral reefs, including global issues like seawater warming, coral bleaching, and ocean acidification, plus human pressures such as unregulated tourism, pollution, and destructive fishing. The right column outlines protection actions, such as functional zoning management, coral cultivation and transplantation, and public engagement via science education and ecotourism.

威胁与保护行动

| 全球威胁：海水升温、珊瑚白化、海洋酸化。 人为压力：无序旅游、污染、破坏性捕捞。 | 保护措施：功能分区管理。 生态修复：珊瑚培育与移植。 公众参与：科普教育与生态旅游。 |

The conclusion slide highlights coral reefs as key nodes in marine ecosystems, essential for safeguarding the ocean's future and serving as a frontline against climate change. It urges action with the subtitle: "Guard the ocean's future, starting now!"

结语

• 珊瑚礁是海洋生态系统的关键节点

• 保护珊瑚礁就是守护海洋未来
• 是应对气候变化的重要前沿阵地

守护海洋未来，从现在开始！},
