珊瑚礁生态系统修复研究进展

A review on ecological restoration techniques of coral reefs

健康的珊瑚礁生态系统具有造礁、护礁、固礁、防浪护岸、防止国土流失的功能。同时,珊瑚礁生态系统生物多样性极高,被称为海洋中的“热带雨林”。我国南海拥有200多个珊瑚岛、礁与沙洲,是世界海洋珊瑚礁最丰富的区域之一。近年来,由于全球气候变化和围填海等人类活动的影响,珊瑚礁生态系统受到了不同程度的影响或破坏,危及海洋生态与岛礁安全,珊瑚礁生态系统的修复至关重要。本文对珊瑚礁生态系统的现状、修复方法及存在的问题进行了总结,并在此基础上创新性地提出了基于系统的珊瑚礁多维生态系统修复模式并付诸实践,以期提供更有效的珊瑚礁生态系统修复新方法。

Coral reefs play vital roles in the construction,protection,and adhesion of reefs,and they protect coastal and national territories as well.Coral reefs have also been considered as tropical rainforests in the marine ecosystem with their abundant biodiversity.More than 200 species of coral reefs exist in the South China Sea;however,some of them have been severely damaged due to natural climate change and human activities in recent years,which threats marine and island safety.Therefore,ecological restoration for coral reef ecosystem is necessary and urgent.In this paper,we summarized the status of coral reefs,technical progress of ecological restoration,and important issues of coral reefs.Furthermore,a novel multidimensional restoration model based on system integrity was proposed and applied in restoring coral reefs,which may provide a new way to restore marine ecosystem.
