摘要
利用养殖期间水体中颗粒有机质垂直迁移通量 ,测定了虾塘自污速率 ;并以虾塘沉积物的 Eh和 Com值为指标 ,结合其空间分布形式 ,初步探讨了虾塘中有机质污染程度。结果表明 ,新、旧虾塘尤其是不同养殖区域间的自污速率都存在明显差别 ;而沉积物中 Eh和 Com值的垂直分布形式 ,则可能成为虾塘有机质污染程度的重要评估参数。
Self pollution rate of organic matter in cultural shrimp pond was quantitatively determined by organic matter flux in cultural waters. Assessment method of the self pollution extent was also promarily studied. The results showed: There were apparent difference about the self pollution rate between new and aged ponds, especially between different culture areas at the same ponds. Because vertical distribution of Eh and C om in sediment were closely related to self pollution condition, it must become a important parameter used to assess organic matter pollution extent in shrimp ponds.
