【摘要】：在积极发展低碳经济背景下,生物碳汇扩增成为低碳发展的重要途径和内容,淡水捕捞是水生生物碳汇的重要组成部分。2016年9月对浙江省平湖市、富阳区、吴兴区的30艘淡水捕捞船进行了生产统计调查,并借助营养级方法评估淡水捕捞渔业碳汇量,研究结果表明:样本船捕捞总产量为117 557 kg,其中鱼类、虾类和螺的产量占比分别为92.87%、0.89%和6.23%,生产具有明显的区域性特征;总的碳汇量评估结果为909.82 t,鱼类、虾类和螺的碳汇量分别为874.40 t(96.11%)、4.07 t(0.45%)和31.35 t(3.45%);与碳含量评估方法相比,营养级方法的评估结果增加了893.68 t,不同方法的评估结论差异明显。最后提出了开展淡水捕捞碳汇量评估方法研究和碳平衡分析等建议,以期为科学评估淡水捕捞渔业碳汇量提供参考。
[Abstract]:In the context of the positive development of low-carbon economy, biological carbon sink amplification has become an important way and content of low-carbon development. Freshwater fishing is an important part of aquatic biological carbon sink. In September 2016, Pinghu City, Zhejiang Province. In Fuyang District, 30 freshwater fishing vessels in Wuxing District conducted production statistics survey, and evaluated the carbon sink of freshwater fishing fishery by means of nutritional grade method. The results showed that the total fishing yield of the sample vessel was 117,557 kg, and the proportion of fish, shrimp and snail were 92.87% and 6.23% respectively. The production has obvious regional characteristics; The total carbon sequestration was 909.82 t, and the carbon sequestration of fish, shrimp and snail was 874.40 t ~ 96.11 t respectively. 4.07 Tu 0.45) and 31.35 t / 3.45%; Compared with the carbon content evaluation method, the evaluation result of nutrition grade method increased 893.68 t. The conclusions of different methods are obviously different. Finally, some suggestions are put forward for the study of carbon sink assessment methods and carbon balance analysis in freshwater fishing, in order to provide a reference for scientific assessment of carbon sinks in freshwater fishing fisheries.
