摘要
1990年5月～1991年2月海坛岛周围海域调查结果表明该海域NO_3-N是无机氮的主要存在形态,NH_4-N的存在也不容忽视.NO_3-N含量冬季高夏季低,夏季东庠岛周围存在上升流,上升流区NO_3-N与S呈显著正相关关系,与T呈显著负相关关系.
The survey results from the area around the Haitan Island from May, 1990 to February, 1991 show that NO3-N is the major form of inorganic nitrogen in the sea area, and NH4-N is also a relatively important one. The contents of NO3-N are the highest in winter and the lowest in summer. There is a upwelling in the sea area around the Dongqiang Island in summer. In the upwelling area there are the significant positive correlation between NO3-N and salinity , and the significant negative correlations between NO3-N and temperature.
