Hainan Tropical Rainforest National Park has the most representative and largest contiguous tropical rainforest in China, which has advantages in exploring the realization mechanism of ecological product value in national parks. Based on the basic framework of "The Technical Guideline on Gross Ecosystem Product (GEP)", we constructed a GEP accounting system in line with the characteristics of tropical rain forest national park, and calculated the GEP of Hainan Tropical Rainforest National Park in 2019. The results showed that the GEP of Hainan Tropical Rainforest National Park in 2019 was 204.513 billion yuan, and the GEP per unit area was 0.046 billion yuan·km. Among all the service types, the value of material services was 4.850 billion yuan, accounting for 2.4% of the total GEP in the national park. The ecosystem regulation service value was 168.891 billion yuan, accounting for 82.6%. The value of cultural services was 30.772 billion yuan, accounting for 15.0%. Among different ecosystem types, the unit area value of the tropical rain forest ecosystem represented by mountain rain forest, lowland rain forest, deciduous monsoon forest, and tropical cloud forest was much higher than that of plantation or other ecosystems, indicating the dominant role of tropical rain forest ecosystem in providing ecosystem services. In addition, based on the GEP accounting results of the national park, we put forward relevant suggestions for further exploring the realization path and realization mechanism of ecological product value.
海南热带雨林国家公园拥有中国最具代表性和最大连片的热带原始雨林，在探索国家公园生态产品价值实现机制方面具有优势。本研究基于“生态系统生产总值（GEP）核算技术规范”的基本框架，构建了一套符合热带森林国家公园特点的 GEP 核算体系，并计算了海南热带雨林国家公园 2019 年的 GEP。结果表明，海南热带雨林国家公园 2019 年的 GEP 为 2045.13 亿元，单位面积 GEP 为 0.046 亿元·km。在所有服务类型中，物质服务的价值为 48.50 亿元，占国家公园总 GEP 的 2.4%。生态系统调节服务的价值为 1688.91 亿元，占 82.6%。文化服务的价值为 307.72 亿元，占 15.0%。在不同的生态系统类型中，以山地雨林、低地雨林、落叶季雨林和热带云雾林为代表的热带森林生态系统的单位面积价值远高于人工林或其他生态系统，表明热带森林生态系统在提供生态系统服务方面发挥着主导作用。此外，基于国家公园的 GEP 核算结果，提出了进一步探索生态产品价值实现路径和实现机制的相关建议。
