摘要:

为了解浙江瑞安牡蛎礁修复区域沉积物碳储量情况,本研究于2024年对瑞安丁山二期(EC、EX)和丁山三期(SX)牡蛎礁修复区的沉积物进行垂直剖面柱采样,探讨该区域沉积物有机碳含量、有机碳密度和有机碳储量的特征。结果表明,EC、EX和SX沉积物有机碳含量平均值分别为0.373%、0.431%和0.203%,有机碳密度平均值分别为2.95×10-3、3.12×10-3和1.35×10-3 g·cm-3。3组沉积物的有机碳含量和有机碳密度,均随深度增加呈波浪状变化,但变化趋势并不一致。相同剖面深度下,SX有机碳储量与EC、EX相比差异显著(p<0.05)。EC沉积物各剖面有机碳储量在0~120 cm沉积物层的总有机碳储量中所占比例最高的剖面是70~80 cm,而EX和SX占比最高的剖面均为20~30 cm。对采自丁山二期(EX)和丁山三期(SX)不同潮间带区域的沉积物进行分组分析,结果显示,有机碳密度和有机碳储量在高、中、低潮带的样品之间无显著差异。本研究结果揭示了瑞安牡蛎礁修复区域沉积物有机碳含量及剖面碳储量分布特征,为该区域开展生态修复效果评估提供了基础数据。

Abstract:

To investigate sediment carbon reserve in the oyster reef restoration area of Rui’an,Zhejiang,China,this study collected vertical sediment cores from the Dingshan Phase Ⅱ(EC,EX)and Dingshan Phase Ⅲ(SX)oyster reef restoration areas in Rui'an in 2024. The characteristics of sediment organic carbon content,organic carbon density,and organic carbon reserve in the study area were explored. The results showed that the average sediment organic carbon contents in EC,EX,and SX were 0.373%,0.431%,and 0.203%,respectively,while the average organic carbon densities were 2.95×10-3,3.12×10-3,and 1.35×10-3 g·cm-3,respectively. The organic carbon content and density of sediments in all three areas exhibited wavelike changes with increasing depth,though their trends were inconsistent across sites. At the same sediment depth,the organic carbon reserve in SX showed significant(p<0.05)differences compared with those in EC and EX. For EC,the 70-80 cm profile had the highest organic carbon storage proportion within the 0-120 cm sediment layer,whereas for EX and SX,the highest proportions were both observed in the 20-30 cm profile. Grouped analysis of sediments collected from different intertidal zones in Dingshan Phase Ⅱ(EX)and Dingshan Phase Ⅲ(SX)revealed no significant differences in organic carbon density and organic carbon reserve among samples from the high,medium,and low tidal zones. These findings revealed the characteristics of sediment organic carbon content and vertical carbon reserve distribution within the Rui’an oyster reef restoration area,providing essential baseline data for evaluating the effectiveness of ecological restoration in this region.
