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。 The self-fouling rate of shrimp ponds was determined by vertical migration fluxes of particulate organic matter in the water body during aquaculture. The Eh and Com values ​​of shrimp ponds were taken as indexes, and the spatial distribution patterns of shrimp ponds were also discussed. The results showed that there was a significant difference in the self-fouling rate between new and old shrimp ponds, especially in different culture areas. The vertical distribution of Eh and Com values ​​in sediments may be an important evaluation parameter for the degree of organic matter pollution in shrimp ponds.
