山东长岛海水养殖碳汇核算与能力评估

Carbon Sink Accounting and Capacity Assessment of Mariculture in Changdao, Shandong Province

为促进长岛碳汇渔业的发展和国家公园的建设,文章首次核算长岛海域养殖贝藻类的碳汇数据,综合评估长岛海水养殖的碳汇能力及其影响因素,并提出对策建议。研究结果表明:长岛海水养殖具有一定的碳汇能力,2016—2020年长岛海域养殖贝藻类的平均碳汇量为2.94万t,其中贝类尤其是扇贝的碳汇量显著高于藻类;养殖结构和养殖产量是长岛海水养殖碳汇能力的主要影响因素,其中养殖产量又受养殖规模、环境、方式和技术等因素的影响;未来长岛发展碳汇渔业应进一步优化海水养殖结构、建立海水养殖碳汇核算体系以及制定和实施相关政策。

In order to promote the development of the carbon sink fisheries and the construction of national parks in Changdao, this paper calculated the carbon sink data of marine bivalves and seaweeds in Changdao for the first time, comprehensively evaluated the carbon sink capacity of mariculture in Changdao and its influencing factors, and put forward countermeasures and suggestions. The results showed that mariculture in Changdao had a certain carbon sink capacity. The average carbon sink of shellfish cultured in Changdao from 2016 to 2020 was 29 400 tons, and the carbon sink of shellfish, especially scallop, was significantly higher than that of algae;the structure and yield of mariculture were the main factors affecting the carbon sink capacity of Changdao mariculture, and the yield of mariculture was also affected by the scale, environment and technology. In the future, the development of carbon sink fisheries in Changdao should further optimize mariculture structure, establish mariculture carbon sink accounting system, and formulate and implement related policies.
