通过1995年4月至1996年1月间对大鹏湾南澳水域网箱养殖区、非养殖区、某养殖场进出水口处海水营养盐(NH4-N，NO3－N，NO2－N，PO4－P）的含量检测，分析了其含量水平、平面与垂直含量分布、含量季节变化以及海水氮磷比值（N／P）和海水营养质量状况。为了解网箱养殖海域自身污染与赤潮发生的关系提供了基础资料。
The results showed that the nutrients (NH4-N, NO3-N, NO2-N and PO4-N) in the cage culture area, the non-culture area and the inlet and outlet of a farm during the period from April 1995 to January 1996, P) content, the content of horizontal and vertical distribution, the content of seasons and the ratio of nitrogen and phosphorus (N / P) in seawater and seawater nutrient quality were analyzed. In order to understand the relationship between cages aquaculture own pollution and the occurrence of red tide provides the basic information.
