| 摘要: |
| 海岸带生态系统固碳增汇是应对气候变化的重要路径。目前海岸带生态系统碳汇潜力的估算研究大多是局地、相对零散的，缺少相对统一的估算标准和估算系统性，且数据资料相对滞后。本研究基于典型海岸带生态系统分布与贝藻类渔业资源状况，系统量化红树林、盐沼、海草床生态系统碳汇和贝藻类渔业碳汇的潜力。结果表明：全国海岸带红树林、盐沼和海草床生态系统每年自然增汇潜力超过60万t C，其中盐沼每年自然增汇潜力约为52万t C，辽宁、山东、江苏、上海、浙江等地增汇潜力较大，年增汇潜力均超过4万t C。2020—2025年渤海滨海盐沼、海草床生态修复与全国红树林保护修复的增汇总量预计将达到40万t C，红树林修复产生的碳汇量约为34万t C。2020—2022年我国养殖贝藻类固碳总量分别为191万t C、228万t C和196万t C，其中贝类固碳占比分别为62%、67%和64%，牡蛎(Ostreidae)、海带(Saccharina japonica)分别为固碳量最大的贝类和藻类，山东、福建、辽宁3省贝藻类养殖固碳量约占全国的70%。在此基础上，本研究讨论了国际核证碳减排标准(VCS)机制、国家核证自愿减排量(CCER)机制、地方碳普惠等海洋碳汇开发机制的应用场景，以期为国家海洋生态保护修复碳汇开发提供支持。 |

| Abstract: |
| Carbon sinks of coastal ecosystems represents a crucial strategy in response to climate change.Current estimations of the carbon sink potential of coastal ecosystems are predominantly localized,fragmented,and hindered by lack of unified estimation standards and systematic assessment and delays in data availability.On the basis of the distribution of typical coastal zone ecosystems and the status of shellfish and algae farming,this paper endeavors to quantify the carbon sink potential of various coastal ecosystems,including mangroves,coastal salt marshes,seagrass meadows,as well as shellfish and algae farming.The results showed that coastal ecosystems in China possessed the natural carbon sink potential exceeding 600 000 t C per year,with salt marshes contributing the largest carbon sink,estimated at 520 000 t C per year.Particularly,Liaoning,Shandong,Jiangsu,Shanghai,and Zhejiang exhibited higher carbon sink potential,which exceeded 40 000 t C per year.The total carbon sink resulting from the restoration of salt marshes and seagrass meadows in the Bohai Sea,in conjunction with national mangrove restoration efforts from 2020 to 2025,was projected to reach 400 000 t C,of which 340 000 t C were attributed to mangrove restoration.Furthermore,the carbon sink contributions from shellfish and algae farming in China from 2020 to 2022 were estimated at 1.91 million t C,2.28 million t C,and 1.96 million t C,respectively,with shellfish accounting for 62%,67%,and 64% of these totals.Notably,Ostreidae and Saccharina japonica were the shellfish and algal species showing the highest carbon sink potential,with the carbon sink contributions in Shandong,Fujian,and Liaoning comprising about 70% of the total.Furthermore,this study discusses the application scenarios for development mechanisms,including international verified Carbon Standard (VCR) mechanism,Chinese Certified Emission Reduction (CCER) mechanism,and local carbon-inclusive approaches,aiming to provide support for carbon sink development from national marine ecosystem protection and restoration. |
