摘要
为减缓全球变暖趋势,海洋碳汇逐渐进入人们的视野,在此基础上我国提出了碳汇渔业的发展理念,可直接或间接实现降低大气中CO_(2)浓度。本研究以辽宁省海水养殖贝藻类主要品种(海带、裙带菜、牡蛎、贻贝、扇贝、蛤、蛏和蚶)为碳汇研究对象,依据《中国渔业统计年鉴》中2010—2019年辽宁省海水养殖贝藻类碳汇的相关数据对辽宁贝藻海洋碳汇能力进行了定量评估。结果表明,辽宁省通过养殖海藻和贝类的方式,10年间总计碳移出量约为267.73万t,相当于减排了982.57万t CO_(2)。有效地证明了海水养殖贝藻类碳汇具有巨大的生态效益,也对辽宁渔业发展有着很可观的经济效益,同时对我国达成碳达峰和碳中和目标具有一定程度的推动性。
In order to slow down the global warming trend,marine carbon sink gradually comes into people′s view,based on which the development concept of carbon sink fisheries has been proposed in China,which can directly or indirectly achieve the reduction of COconcentration in the atmosphere.In this paper,the main species of marine aquaculture shellfish and algae in Liaoning Province(Saccharina japonica,Undaria pinnatifuda,Crassostrea gigas,Mytilus galloprovincialis,Placopecta magellanicus,Ruditapes philippinarum,Sinonovacula constricta and Scapharca subcrenata)were used as carbon sink research objects,and the capacity of marine carbon sink of shellfish and algae in Liaoning Province was quantitatively assessed based on the data related to carbon sink of marine aquaculture shellfish and algae in Liaoning Province from 2010 to 2019 in the China Fisheries Statistical Yearbook.The results showed that the total amount of carbon removed by seaweed and shellfish farming in Liaoning Province during the ten-year period was about 2,677,300 t,which was equivalent to the reduction of 9,825,700 t COfor Liaoning Province.It also had a certain degree of promotion for China to reach the carbon peak and carbon neutral goal.
