南海深海生物多样性国际研究态势与热点分析

南海是西太平洋边缘海,有陆架、陆坡、岛礁、深海平原、海山、冷泉等多种生境,近10年来南海逐渐成为世界深海研究的热点。南海是中国海洋生物多样性最高的区域,与作为海洋生物多样性中心的印太珊瑚大三角区具有一定的环境与生物连通性,对南海的深海生物探测研究可丰富对西太平洋及印太交汇区生物多样性及地理分布格局的认知。目前有关南海的生物多样性研究主要集中在北部陆架浅海及岛礁,对于深海生物多样性认知明显不足。本研究梳理了全球深海生物多样性的主要国际战略布局,并对南海深海生物多样性SCIE论文发表情况进行了综合分析,探讨了南海深海生物多样性研究态势,对未来南海深海生物多样性调查与研究提出了研究展望和建议。

Analysis of international trends and hotspots in research on deep-sea biodiversity in the South China Sea

The South China Sea is a marginal sea of the Western Pacific Ocean, with numerous habitats, such as continental shelves, continental slopes, reefs, abyssal plains, seamounts, and cold seeps. Over the past ten years, the South China Sea has gradually become a hotspot in deep-sea research. The sea has the highest marine biodiversity in China and has certain environmental and biological connectivity with the Coral Triangle, the world''s center of marine biodiversity. The exploration and investigation of deep-sea organisms in the South China Sea will enrich the understanding of biodiversity and geographical distribution patterns in the Western Pacific and Indo-Pacific convergence region. Studies on the biodiversity in the South China Sea have mainly focused on the shallow waters and reefs on the northern continental shelf, and the knowledge of deep-sea biodiversity is insufficient. This study reviewed the major international strategic layouts and research programs in deep-sea biodiversity, analyzed SCIE papers on deep-sea biodiversity in the South China Sea, and summarized the research situation and trends. Future research prospects are proposed for the investigation of deep-sea biodiversity in the South China Sea.
