对于围隔养殖对虾生态系中有机碳的变动进行了研究 ,结果表明 :溶解有机碳 (DOC)含量波动在 5 .2 99～ 13.39mg/ L之间 ,平均为 8.5 3mg/ L± 2 .2 5 mg/ L;颗粒有机碳 (POC)含量波动在0 .6 5～ 6 .6 3mg/ L之间 ,平均为 3.2 5 mg/ L± 1.76 mg/ L;总有机碳 (TOC)含量波动在 6 .92～ 2 0 .0 2mg/ L之间 ,平均为 11.78mg/ L± 3.82 mg/ L ;其中 DOC∶ POC∶ TOC为 0 .72∶ 0 .2 8∶ 1。各种有机碳组分的含量明显高于自然海水中各种有机碳的含量 ;各种有机碳组分的含量在养殖期间总体上呈上升的趋势 ;其变化与 DCOD的变化呈显著线性正相关的关系。
The results showed that the content of dissolved organic carbon (DOC) fluctuated between 5.299 ~ 13.39mg / L and the average was 8.53mg / L ± 2. 2 The content of total organic carbon (POC) fluctuated between 0.56-6.3 mg / L and the average was 3.2 5 mg / L ± 1.76 mg / L. The content of total organic carbon (TOC) fluctuated between 6 .92 ~ 20.2 mg / L, with an average of 11.78 mg / L ± 3.82 mg / L; of which DOC: POC: TOC was 0.72: 0.28: 1. The contents of various organic carbon components were significantly higher than those of natural seawater. The contents of various organic carbon components showed an overall upward trend during the cultivation period. The changes were positively correlated with the changes of DCOD Relationship.
