摘　　要：黄海绿潮自2007年至今连年暴发,对海上交通、滨海旅游、水产养殖等方面造成不同程度危害。大量研究表明,苏北辐射沙洲紫菜养殖区是绿潮源头,且筏架绿藻人为入海是绿潮主要来源。为了防控绿潮灾害,现有方法为物理打捞法和化学法,耗费大量人力物力。本文在紫菜养殖区现场调研分析基础上,提出了一种绿潮早期防控方法—筏架下沉法,并基于此方法结合已有物理打捞、化学方法,设计了一套筏架区绿潮早期综合防控方案。本文提出的筏架下沉法具有环保、经济的优势,综合防控方案可为绿潮灾害防灾减灾提供重要参考。Green tide in the Yellow Sea has been erupting every year since 2007,causing different degrees of marine environment harm to marine traffic,coastal tourism and aquaculture.A large number of studies have shown that the porphyra culture area in subei shoals is the source of the green tide,and the main source of the green tide is algae abandoned on the shoals.In order to control and prevent the green tide disaster,the existing methods include physical salvage method and chemical method,which cost a lot of manpower and material resources.Therefore,based on field investigation and analysis in porphyra raft area,this paper proposed an earlystage green tide control and prevention method--raft sinking method,and based on this method combined with existing physical salvage,chemical method,put forward a set of early-stage green tide control and prevention plan in raft area.The raft sinking method proposed in this paper has the advantages of environmental protection and economy,and the comprehensive control and prevention plan proposed in this paper can provide important reference for disaster prevention and mitigation of green tide disasters.
