摘要:
海藻养殖碳汇是渔业碳汇的重要组成部分,分析海藻养殖产量与碳汇量变动关系具有重要意义。从海藻养殖碳汇核算原理出发,分别设计3种海藻养殖情景模式:基准情景、海带积极型情景和海带消极型情景。分析表明,与基准情景相比,海带积极型情景下,海带养殖形成碳汇量较多;相反,海带消极型情景则会减少海藻养殖碳汇。根据海带积极型情景的预测,预计到2020年我国海藻养殖碳汇总量可达到118.9万t,较基准情景增加了碳汇量152.75 t,由此认为提高海带养殖比重有助于我国提高海藻养殖碳汇总量。

Abstract:
Algae carbon constitutes an important part in fishery carbon sinks. Three algae development scenarios, namely, the baseline, kelp positive and kelp negative, were designed to evaluate their effect on fishery carbon sinks. The results showed that, in comparison with the baseline scenario, the kelp positive type increased, while the kelp negative type reduced the carbon sink. The kelp positive type would aggregate algae carbon sinks to reach 1.189 million tons in 2020. That would be 152.75 tons more than the baseline could provide. It was, therefore, speculated that kelp aquaculture could be applied as an important means for increasing the fishery carbon sink.
