摘要
根据1990年夏季大鹿岛海域无机氮、无机磷、化学耗氧量及溶解氧调查资料,计算该海域富营养化及有机污染指数,揭示出大多数站位水质已呈富营养化状态,有机污染严重,模糊聚类分析将该海域水质划分出4种类型,分别是贫营养型、开始富营养化型、高COD富营养化型及高氮、磷富营养化型。河流排污和海水养殖废水污染是导致海域富营养化的主要因素。
In this paper, indexes of eutrophication and organic pollution are calculated by using the survey data on inorganic nitrogen, inorganic phosphorus, chemical oxygen demand and dissolved oxygen in the sea area around Dalu Island in 1990. The results show that most part of the sea area is eutrophic and organic pollution is heavier. The water quality in the area is divided into four types by fuzzy cluster. They are clean, initialy eutrophic, rich COD eutrohpic and rich N and P eutrophic type respectively. The eutrophication is caused by pollutant discharge of the river and by sea farming pollution in the sea area.
