摘要:
八放珊瑚广泛分布在近岸浅海到深海,以及热带、温带甚至寒带等高纬度海区,在维持海洋生态系统结构完整性和生物多样性方面发挥了重要作用。受气候变化和人类活动影响,八放珊瑚呈现不断衰退趋势,忽视海洋生态系统原生物种自然禀赋的现象明显,尤其是八放珊瑚可供头足类产卵附着的生态功能尚未引起足够重视。本文综合梳理了八放珊瑚的结构和分类、繁殖特性和生殖方式、影响生态因子和退化原因等研究现状和问题,提出针对性保护和修复八放珊瑚的对策与建议,以期为我国重要生态系统保护和修复重大工程的实施提供基础资料。

Abstract:
Octocorallia corals are widely distributing in shallow to deep coastal waters across tropical, temperate, and even boreal zones and other highlatitude marine waters. Octocorallia play an important role in maintaining the structural integrity and biodiversity of marine ecosystems. Due to the influence of climate change and human activities, Octocorallia shows a trend of continuous decline. The phenomenon of neglecting the natural endowment of native species in marine ecosystems is noticeable, and especially the ecological function of Octocorallia for cephalopod spawning attachment has not yet received sufficient attention. In this paper, we comprehensively reviewed the current status and problems of the structure and classification, reproductive characteristics and mode of reproduction, ecological factors and causes of degradation of Octocorallia, and proposed countermeasures and suggestions for the conservation and restoration of Octocorallia. We hope it can provide fundamental information for the implementation of major projects for the conservation and restoration of essential ecosystems in China.
Key words:  marine biology  Octocorallia  ecological factors  causes of degeneration  reproductive mode  conservation  restoration
