    摘要:

    为研究枸杞岛贻贝养殖海域不同季节碳通量及固碳能力, 本研究在 2020―2021 年监测和分析了养殖海域温度、盐度、pH、总碱度(TA)及水体中溶解无机碳(DIC)、溶解有机碳(DOC)、颗粒有机碳(POC)分布特征, 估算了枸杞岛贻贝养殖海域表层海水二氧化碳分压(pCO2)及海–气界面二氧化碳交换通量(FCO2)值, 并分析 pCO2 的影响因素, 探讨枸杞岛贻贝养殖海域固碳能力。结果表明, 枸杞岛海域表层海水 4 个季节的温度、盐度、pH、TA、DIC、 DOC、POC 的空间分布在季节上差异极显著(P<0.01)。枸杞岛海域 pCO2 全年的变化范围为 65.19~719.1 μatm, 水团混合和生物活动等是影响海域表层海水 pCO2 的重要因素。枸杞岛贻贝养殖海域 FCO2 值的变化范围为–63.75~ 99.18 mmol/(m2 ·d), 四季变化极显著(P<0.01), 全年碳分布格局有较大差异, 其中, 春、夏、秋三季均为碳汇, 分别为 (–18.86±12) mmol/(m2 ·d), (–11.59±7.95) mmol/(m2 ·d), (–3.61±37.22) mmol/(m2 ·d), 冬季为碳源[(78.24±5.09) mmol/(m2 ·d)]。枸杞岛贻贝养殖区 FCO2 值均高于外海非养殖区, 且达到显著水平(P<0.05), 是弱汇区。本研究区域内贝壳固碳量为 18425.59 t, 贻贝软组织固碳量为 4973.97 t, 单位面积贻贝固碳量达 22.83 t/hm2 。该研究可为贝类养殖碳汇评价提供参考。
