基于模糊综合评价的桑沟湾增养殖区富营养化水平分析

On the Eutrophication Level of Mariculture Zone in Sanggou Bay Based on Fuzzy Synthesis Evaluation

文章简要回顾海洋水体富营养化评价方法,探索建立海水养殖区富营养化水平模糊综合评价模型,并就桑沟湾海水养殖区的化学需氧量、无机氮(硝酸盐、亚硝酸盐和氨氮之和)、活性磷酸盐、溶解氧、pH值、叶绿素a等指标进行了不同时段、不同时空的综合评价,系统分析综合评价结果的合理性,与其他富营养化评价方法进行了比较,得出用模糊综合评价方法取得的结果更有利于指导海水养殖生产的结论。

Fuzzy synthesis was used for the evaluation of eutrophication in mariculture zone of-Sanggou Bay.The COD,DIN,DIP,dissolved oxygen,pH and chlorophyl-a were assessed by different periods and spaces in Sanggou Bay.The rationality of evaluation results was analyzed. Compared with other evaluation methods,fuzzy synthesis was considered to be the best method to assess the eutrophication level of mariculture zone.
