大鹏湾南澳养殖水域的氮、磷含量特征

CHARACTERISTICS OF NITROGEN AND PHOSPHORUS CONTENTS IN NAN'AO WATERS OF DAPENG BAY

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。

Based on the content detedrination of nutrient salts (NH4-N, NO3-N,NO2-N, PO4-P) in the cage cultUre are4 the non-culture area and the outlet of somefarming ground in the Nan'ao waters of the Dapeng Bay from April 1995 to January1996, the paper analyzes the content levels,the horizontal and vertical distributionsand the seasonal change of nutrient salts, as well as the ratio of nitrogen tOphosphorus and the quality .status of nutrient salts in the seawater, offeringfundamental data for understanding the self-pollution of cage culture area and itsrelation with red tide.
