摘　　要：为确定河北省海水养殖贝类、藻类的固碳能力,根据河北省近8年的养殖产量,参考有关贝藻含碳率,测算出养殖贝类、藻类的总固碳量;并利用Tapio脱钩模型分析了海水贝藻养殖固碳与海水贝藻养殖经济的关系。结果表明:2012—2019年河北省贝藻总固碳量为334448.47 t,相当于减排二氧化碳1226311.07 t,创造经济价值约为0.62亿元;2012—2019年河北省海水贝藻养殖碳汇与海水贝藻养殖经济脱钩关系呈现弱脱钩、扩张连接、强脱钩、弱负脱钩和扩张负脱钩等5种类型。根据上述数据表明,河北省海洋碳汇作用巨大,今后应大力合理发展碳汇渔业产业。In order to determine the carbon sequestration capacity of shellfish and macroalgae marine culture in Hebei Province,the total carbon sequestration capacity of cultured shellfish and macroalgae were calculated based on the cultivation output of Hebei Province in the past 8 years and the carbon content of related shellfish and algae.The Tapio decoupling model was used to analyze the relationship between the carbon fixation of shellfish and macroalgae cultivation and the economics of shellfish and macroalgae marine cultivation.The results showed that the total carbon sequestration of shellfish and macroalgae from 2012 to 2019 in Hebei Province was 334448.47 t,which is equivalent to reducing carbon dioxide emissions by 1226311.07 t,creating economic value of approximately 62 million yuan.The relationship between the carbon sink of shellfish and macroalgae culture and the economic decoupling of shellfish and macroalgae marine culture in Hebei Province showed five types:weak decoupling,expansion connection,strong decoupling,weak negative decoupling and expansion negative decoupling from 2012 to 2019.According to the above data,Hebei Province has a huge role to play in marine carbon sinks,and the carbon sink fishery industry should be vigorously and reasonably developed in the future.
