摘　　要：为了明确南海常见双壳贝类碳含量及评估广东、广西和海南养殖双壳贝类固碳量,对21种热带常见双壳贝类壳碳含量及软体部碳含量进行了测定,同时基于所测贝类碳含量,对广东、广西和海南2022年养殖双壳贝类固碳量进行了统计分析。结果显示:21种双壳贝类软部碳含量为31.33%~43.20%,缢蛏最高,橘色海菊蛤最低;壳碳含量为11.32%~14.35%,翡翠贻贝最高,华贵栉孔扇贝最低;所测双壳贝湿重碳含量为7.10%~11.48%,栉江珧最低,缢蛏最高;广东、广西和海南2022年养殖双壳贝类固碳总量分别为145936、104645和164 t,养殖区单位面积固碳量分别为2.78、3.14和0.15 t·hm^(-2)。To detect the carbon contents of common bivalve mollusks in the South China Sea and evaluate the carbon sequestration capacity of bivalve mollusks cultivated in Guangdong,Guangxi and Hainan,this study measured the carbon contents in the shells and soft tissues of 21 common tropical bivalve mollusks.Additionally,based on the carbon contents of these mollusks,a statistical analysis was conducted on the carbon sequestration capacity of bivalve mollusks cultivated in Guangdong,Guangxi and Hainan in 2022.The results showed that the carbon contents of soft tissues in 21 bivalve mollusks ranged from 31.33%~43.20%,with the highest being observed in Sinonovacula constricta and the lowest in Spondylus aurantius;the carbon content of their shells ranged from 11.32%to 14.35%,with the highest in Perna viridis and the lowest in Mimachlamys nobilis;the carbon content of the whole body wet weight ranged from 7.10%to 11.48%,with the lowest content found in Atrina pectinata and the highest in Sinonovacula constricta.The total carbon sequestration capacities of bivalve mollusks cultivated in Guangdong,Guangxi and Hainan provinces in 2022 were 145,936,104,645 and 164 t,respectively;the carbon sequestration capacities per unit area in these provinces were 2.78,3.14 and 0.15 t·hm^(-2),respectively.
