海山生物多样性研究近10年国际发展态势与热点

Analysis of the international trend and research hotspots of seamount biodiversity research in the past decade

海山是全球深海生物多样性的汇聚区,且以其高富钴结壳资源和高渔业资源成为深海探测研究热点。海山生态系统易受到人为活动的影响,海山及其冷水珊瑚被认为是脆弱海洋生态系统的重要构成部分。对海山生物多样性的破坏以及过度开发可能对海洋健康造成不可逆的严重影响,法律和地缘政治等因素的影响也使得保护海山生物多样性面临很多挑战。本研究对海山生物多样性近10年(2001—2020年)的国际研究计划以及论文发表情况进行了综合分析,探讨了海山生物多样性研究的国际发展态势和研究热点,为海山生物多样性研究、保护与管理及相关国际合作的开展提供参考。

Seamounts are the global reservoirs of deep-sea biodiversity and have become a hot spot for deep-sea exploration and research due to their high cobalt-rich crust resources and high fishing resources.Seamounts are vulnerable to human activities such as bottom trawling and thus seamount ecosystems and their cold-water corals have been considered as important components of Vulnerable Marine Ecosystems(VMEs).The destruction of seamounts and overexploitation may have an irreversible and serious impact on seamounts'biodiversity and the health of the ocean.Legal and geopolitical factors also bring great challenges to seamount biodiversity and conservation.This research conducted a comprehensive analysis on the international programs and the publication output of seamount biodiversity in the past decade(2001-2020),to illustrate the international trend and research hotspots of the seamount biodiversity research.We aim to provide information for the research,conservation and management of seamount biodiversity as well as related international cooperation.
