Assessment of carbon sequestration capacity of marine aquaculture shellfish and algae in Shandong Province
摘要
Abstract
The continuous increase in atmospheric CO2 concentration has had a significant impact on biodiversity and social development.China is one of the major carbon emitting countries,and carrying out reduction of emission and increase of sink is an inevitable way for China to achieve carbon peaking and carbon neutrality goals.Reducing CO2 concentration in the atmosphere through ocean carbon sequestration is an effective way to mitigate global climate change,protect biodiversity,and achieve sustainable development.In recent years,the fishing carbon sink by mariculture of shellfish and algae has attracted much attention.Researchers have used different estimation methods to estimate their carbon sink capacity,but there are significant differences in the results.The scale of marine aquaculture production of Shandong has been among the top in China for many consecutive years.To understand the status and carbon sink development potential of shellfish and algae aquaculture in Shandong,this study analyzed the data of shellfish and algae aquaculture in Shandong from 2016 to 2021 and calculated its carbon sink capacity.This is the first time in China that a standard accounting method has been used to estimate carbon sequestration capacity.The research results indicate that the carbon sink capacity of shellfish and algae aquaculture in Shandong Province has remained basically stable.The carbon sink capacity of shellfish aquaculture is 33.86×104 t·y-1,and that of algae is 3.91×104 t·y-1.Among them,scallops and Laminaria japonica are the species with the highest carbon sink capacity in shellfish and algae aquaculture.The carbon sink capacity of shellfish is significantly higher than that of algae.There are significant differences in the types of aquaculture in different cities,showing obvious spatial clustering characteristics.The regions with high carbon sink capacity are mainly Yantai,Weihai,and Qingdao,accounting for 75％of the province.The carbon sink capacity of shellfish and algae aquaculture is closely related to its yield.Shandong Province has a huge production of shellfish and algae aquaculture.According to the standard method,it is calculated that the potential for carbon sink in shellfish and algae aquaculture in Shandong is enormous.Mariculture can not only bring considerable economic and social benefits,but also ecological benefits.The carbon sink calculation for marine aquaculture of shellfish and algae is an effective way to achieve carbon peaking and carbon neutrality and is the foundation for establishing a carbon trading market.It is of great significance for comprehensively understanding the carbon sink potential of marine fisheries in Shandong Province.关键词
