低碳是海洋循环经济实现的重要途径, 实现海洋渔业的碳平衡是海洋传统经济转变的重要发展方式。本文通过对2013—2022年全国及沿海9省(区)的海洋捕捞碳排放量与碳汇量测算, 在此基础上分析了全国及沿海9省(区)的碳平衡状态, 并利用灰色关联度分析碳平衡状态影响因素的关联度。结果表明除2020年-2022年山东省的碳平衡状态为盈余外, 其他均为碳赤字状态。对于碳平衡状态的影响因素, 总体来看全国与沿海9省(区)关联度较大的是海洋捕捞产量、捕捞人员数量和海水养殖面积。最后从加快渔船的升级改造与更新淘汰、调整捕捞的作业方式、提高海水养殖贝藻类的养殖规模以及加快渔业专业合作组织的建立和加速推广渔业碳汇交易提出相关对策建议, 以期尽快地实现海洋渔业的碳平衡。 |

Abstract: |
Low carbon is crucial in realizing the circular economy of the ocean, and achieving carbon balance in marine fisheries is a critical development method for transforming the traditional economy of the ocean. This study analyzes the carbon balance in China in general and nine coastal provinces (districts) in particular on the basis of the carbon emissions and sinks in marine fishing from 2013 to 2022. The results show that except for Shandong Province, which has a carbon balance status of surplus in 2020-2022, all others have a carbon deficit status. As for the factors affecting the carbon balance status, in general, the factors that have a greater correlation with the nine coastal provinces (districts) in the country are marine capture production, the number of fishing personnel and the area of mariculture. Finally, we propose countermeasures to accelerate the upgrade and renovation of fishing vessels, adjust the operation mode of fishing, and increase the scale of mariculture shellfish and algae farming. Furthermore, we provide recommendations for hastening the establishment of professional fishery cooperative organizations and accelerating the promotion of fishery carbon trading to achieve carbon balance in marine fisheries as soon as possible. |
