摘　　要：在践行渔业节能减排战略背景下,为了解山东省海水养殖污染物负荷及能耗现状,采用竹内俊郎法对海水鱼类及虾类的氮、磷污染负荷量,工厂化和海水池塘两种养殖方式的能耗进行了评估和分析。结果表明:山东省海水鱼类氮、磷污染负荷分别为147.90和16.00 kg/t,虾类氮、磷污染负荷分别为64.03和22.10 kg/t,海水鱼虾养殖氮、磷污染负荷总量为2.63×10^4和0.48×10^4 t/a。养殖能耗约为8.26×10 8 kW h/a,工厂化和海水池塘能耗分别为5.64×10^8和2.62×10^8 kW h/a。养殖结构和养殖方式对污染负荷和能耗具有重要影响,积极推广工厂化循环水等技术模式对渔业节能减排具有重要作用。As a response to‘energy-saving and emission-reduction’strategy,in order to investigate the status of pollution loads and energy consumption of marine aquaculture in Shandong Province,pollution loads were estimated by ZHU NEI JUN LANG method for sea fish and shrimp,while energy consumption was calculated for the industrialized and pond culture pattern.The results showed that nitrogen and phosphorus pollution loads of sea fish were 147.90 kg/t and 16.00 kg/t,nitrogen and phosphorus pollution loads of shrimp were 64.03 kg/t and 22.10 kg/t,total amount of nitrogen and phosphorus pollution loads in Shandong were 2.63×10^4 t/a and 0.48×10^4 t/a,respectively.Energy consumption was 8.26×10^8 kW h/a,including 5.64×10^8 kW h/a for the industrialized culture and 2.62×10^8 kW h/a for the pond culture.The structure and mode of marine aquaculture is important for the pollution loads and energy consumption.It plays an import role for the‘energy-saving and emission-reduction’strategy to extend the technologies such as recirculating aquaculture systems.
