摘要:

贝类是海洋生态系统重要组成部分, 通过生命活动利用和固定海水中CO2, 发挥重要碳汇作用。本文基于碳储量法探究了烟台各海域不同种类、规格贝类的固碳能力。不同种贝类固碳能力差别巨大, 其固碳能力随着个体增大显著增强。其中养殖型长牡蛎(Crassostrea gigas)、野生型长牡蛎(Ostrea plicatula)、栉孔扇贝(Chlamys farreri)、海湾扇贝(Argopecten irradians)及紫贻贝(Mytilus galloprovincialis)的固碳能力分别为3.37~16.64、2.87~14.17、0.21~2.10、0.87~1.58及0.21~0.38g·a-1·ind-1。牡蛎的固碳能力远远高于扇贝和贻贝(P<0.01), 而不同海域相同贝类的固碳能力无显著差异(P>0.01)。此外, 基于贝类碳汇计量指标的实际测定值与标准参考值进行烟台市主要养殖贝类碳汇量核算发现, 牡蛎碳汇量实测值显著高于标准估算量(P<0.01), 而扇贝的碳汇量实测值显著低于标准估算量(P<0.01), 长岛海域海湾扇贝及贻贝的碳汇实际核算量与标准估算量之间差异显著(P<0.01)。贝类固碳能力与其种类及个体大小直接相关, 表明贝类碳汇计量模型中参数的设定不仅要考虑养殖品种, 也要考虑个体大小的组成。

Abstract:

Bivalves play an important role as carbon sinks by absorbing and fixing CO2 in seawater. This study explores the carbon sequestration capacity (CSC) of different species and sizes of bivalves cultivated in Yantai sea areas to determine their carbon stocks. The results showed that the CSC of different species varied greatly, and increased significantly with the individual size. The CSC of Crassostrea gigas (farmed C. gigas), Ostrea plicatula (wild C. gigas), Chlamys farreri, Argopecten irradians and Mytilus galloprovincialis were 3.37’16.64, 2.87’14.17, 0.21’2.10, 0.87’1.58 and 0.21’0.38 g·a-1·ind-1, respectively. The CSC of oysters was much higher than that of scallops and mussels (P<0.01), and there was no significant difference among sampling sites. In addition, based on the measured and the standard reference values of bivalves carbon sink evaluation parameters, the actual measured amount of oyster carbon sinks in three study areas of Yantai was significantly higher than the estimation based on standard reference values (P<0.01), but the result was opposite for scallops. There was significant difference between the actual measured amount of carbon sinks and the standard estimation of A. irradians and M. galloprovincialis in Changdao waters (P<0.01), which was related to bivalve species and individual sizes. The results showed that the setting of parameters in the bivalve carbon sink evaluation model should take into account not only the composition of the species but also the individual size.

Key words: bivalve, carbon sequestration capacity, carbon sink, Yantai sea areas
