| 摘 要： | 根据2002年4月-2003年1月对哑铃湾网箱养殖的调查数据，分析了养殖水体中不同形态N／P值的分布趋势、季节变化及哑铃湾网箱养殖水体中的限制性营养盐。结果表明：各形态N／P具有显著的季节变化，其分布趋势基本表现为网箱养殖区低于非养殖区，并且随着养殖年限的增加，这种现象更明显。总体上说，哑铃湾浮游植物生长主要受P的限制，但从无机态N／P来看，春、夏季以P为该海域浮游植物生长的控制因子：秋、冬季以N为该海湾浮游植物生长的控制因子。

| Abstract: | Based on the investigations from April 2002 to January 2003, the distribution, seasonal change and the limiting nutrient of the cage culture in the Yaling Bay were analyzed. The results showed that the various forms of N/P rations have obvious seasonal changes; those in the cage culture area were lower than in the non-cage culture, and the phenomenon was more evident with time. Phosphorus was the limiting factor of phytoplankton on the whole in the Yaling Bay. However, according to inorganic N/P rations, phosphorus was the limiting factor in spring and summer, and nitrogen in autumn and winter. |
