中文摘要
        珊瑚礁是生产力水平最高,同时也是最脆弱的海洋生态系统之一。由气候变化及人类活动导致的珊瑚礁全球衰退,已经影响到珊瑚礁的钙化和碳循环过程,也加大了长期悬而未决的珊瑚礁二氧化碳(CO2)“源-汇”争议。尽管珊瑚礁的钙化过程伴随CO2释放,但考虑到珊瑚礁生态系统内部复杂的生物地球化学循环过程,以及造礁珊瑚特殊的混合营养特性,其作为碳汇功能的属性也不容忽视。文章从提高珊瑚礁对气候变化的弹性适应角度出发,尝试厘清有关珊瑚礁生态系统的CO2“源-汇”争议,探索将珊瑚礁由碳源向碳汇转变的生态调控方式和途径,以期为实施海洋负排放、践行国家碳中和战略提供理论和技术支撑。
英文摘要
        Coral reefs are one of the most productive, and yet most vulnerable marine ecosystems. The global decline of coral reefs induced by climate change and human activities has already affected the processes of coral calcification and carbon cycling in the reef ecosystem, intensifying the long-standing CO2 "source-sink" debate over coral reefs. Despite the fact that coral calcification is accompanied by the release of CO2 to the atmosphere, the significance of coral reefs as a carbon sink cannot be ignored, given the complex biogeochemical processes in the reef ecosystem and the characteristic mixotrophic lifestyle of the reef-building corals. From the perspective of increasing coral resilience to climate change, this study attempts to clarify the controversy over the coral reef CO2 "source-sink" debate, explore the possible ecological regulations and pathways to transform coral reefs from a carbon source to a carbon sink, and provide theoretical framework and technical support for the deployment of ocean negative carbon emissions and the implementation of the national carbon neutrality strategy
