摘要:
海水贝藻类养殖碳汇是海洋渔业碳汇的重要组成,开展其碳汇研究对服务我国实现碳中和目标有积极的作用。福建省的海水养殖规模和产量居于全国前列,对其海水贝藻类养殖碳汇及潜力评估有重要的意义。本研究分析了2015至2020年度《中国渔业统计年鉴》海水贝藻类养殖数据,估算了2014年至2019年全国及福建省海水贝藻类养殖碳汇强度,并评估了福建省贝藻类养殖碳汇潜力。研究结果表明,福建省在全国贝藻类养殖碳汇强度占比较大,且逐年递增,在2019年估算的碳汇强度高达211.3万吨(占全国估算总值的31.16%)。与全国海水贝藻类碳汇增速17.3万吨/年相比,福建省的年增速数据(10.7万吨/年)表明福建省具有较强的海水贝藻类养殖碳汇潜力,并可带来可观的减排经济效益,为我国实现碳中和这一宏伟目标做出重要贡献。

Abstract:
The carbon sequestration of marine shellfish and seaweed cultures is an important part of fishery carbon sequestration. The assessment of carbon sequestration in marine shellfish and seaweed cultures is beneficial for realizing the purpose of carbon neutrality in China. The scale and output of marine culture of Fujian Province are in forefront of the country, therefore, it is of great significance for the study of carbon sequestration in Fujian. Using the data of the Chinese Fisheries Statistical Yearbook published from 2015 to 2020, we evaluated the carbon sequestrations and its potentialities in Fujian Province and China from 2014 to 2019, respectively. The results indicated that the carbon sequestration of Fujian Province accounted for a large proportion and it increased significantly yearly. Impressively, the estimated carbon sequestration strength in 2019 was up to 2.113 million tons, accounting approximately for 31.15% of the total of the whole country. Compared with the annual growth rate of the country (about 0.173 million tons per year), the annual growth rate of marine cultivated shellfish and seaweed carbon sequestration in Fujian Province is approximately 0.107 million tons per year, which indicated that Fujian Province has strong potentiality of carbon sequestration in marine culture. It is optimistic that the marine culture of shellfish and algae in Fujian Province could bring considerable economic benefits for the reduction of carbon emission and make an important contribution to realizing the carbon neutralization in China.
Key words:  marine environmental science  carbon neutrality  shellfish  seaweed  carbon sequestration  Fujian Province
