| 摘要: |
| 深海被认为是地球上尚未被认识和开发的“最后疆域”，深海环境不仅可满足人类对未来资源的部分需求，还孕育出了独特的生态系统和特殊的生命过程。地球上绝大部分生态系统是利用光合作用来维持生命循环，而深海中存在着以化能合成为基础的生态系统。本文重点综述了国内外关于深海化能生态系统中大型生物多样性及其起源演化方面的研究进展，并对印太交汇区深海极端环境的生物多样性研究趋势和发展方向进行了展望。 |

| Abstract: |
| The deep sea is the largest and least explored habitat on the Earth. Exploitation of the Earth's last place will meet a part of human demand for future resources. In addition, the unique ecosystems and extreme life processes have been discovered in the deep ocean. Most ecosystems on the Earth use photosynthesis to sustain life cycles, while in the deep ocean the chemosynthetic ecosystems are based on chemical synthesis. In the present paper, the research progress of the origin, evolution, and biogeography of megafauna biodiversity in deep-sea chemosynthetic ecosystems in the world was reviewed systematically, and the prospect of the further studies on the deep-sea biodiversity in Indo-Pacific region was discussed specifically. |
