摘    要:本文根据1987年对虾养殖期间丁字湾海域的调查结果,以 IN、IP、COD和 DO为指标参数分析了该海域有机质和营养盐的污染状况和营养类型。分析结果表明,大面积对虾养殖排出的虾塘废水,能引起丁字湾海域有机质和营养盐的严重污染和富营养化,并且这种污染程度和营养类型有明显的季节变化。本文对丁字湾海域的赤潮能否形成也进行了预测。

关 键 词:有机质  营养盐污染  营养状况  海域

Abstract:Pollution condition of organic matter and nutrient salts and nutri-tion type were analysed to the investigation of Dingzi Bay waters during shrimpculture season in 1987. The results showed that the waste water discharged fromlarge area shrimp ponds could result in eutrophication in the bay and thus causeserious pollution of organic matter and nutrient salts. Pollution degree and nutri-tion type evidently varied in season. IP was a restrictive factor that limited theincrease of primary production in the waters. The possibility of occurance of redtide in Dingzi bay waters was also discussed.
Keywords:nutritional condition  pollution of organic matter and nutrient salts  nutrition type  waste water discharged from shrimp ponds
