| 摘要: |
| 为了解渤海湾近10 a来渔业碳汇能力,本研究汇总了渤海湾地区2010—2020年海水养殖的品种和产量。通过建立不同养殖品种固碳能力评估体系,计算了不同养殖品种对渔业碳汇的贡献和渤海湾近10 a海水养殖固碳总量。结果表明,2010—2020年渤海湾海水养殖以池塘养殖为主要养殖模式,年固碳量从2010年的5.79万吨增至2020年的11.04万吨,10 a内共计固碳96.0万吨,平均碳转化比为12.5%,其中山东省贡献超过65%。该探索对建立“渔业碳汇”计算的指标体系、科学发展碳汇渔业、提升海洋碳汇生态价值具有一定的指导意义。 |

| Abstract: |
| To understand the carbon sink capacity of fisheries in Bohai Bay in the recent decade, the varieties and yields of mariculture in Bohai Bay from 2010 to 2020 were collected. A carbon sequestration capacity assessment system of mariculture was established to calculate the contribution of different species to the fishery carbon sink and the total carbon sequestration of marine aquaculture in Bohai Bay in a recent decade. The results showed that pond aquaculture was the main aquaculture mode in Bohai Bay from 2010 to 2020. Annual carbon sequestration amounts increased from 57 900 tons to 110 400 million tons, and the average carbon conversion ratio was 12.5%. A total of 960 000 tons of carbon were sequestered, of which Shandong Province contributed >65%. The results have a certain guiding significance for establishing a “fishery carbon sink” calculation system, transforming China’s offshore marine carbon sink economy, the scientific development of the fishery carbon sink, and promoting marine carbon sink ecological value. |
