| 摘 要： | 根据2002至2003年福宁湾海域的监测资料,研究该海域PO4-P、DIN的时空变化特征、营养程度现状以及本海域的营养盐限制因子.研究表明：PO4-P、DIN含量均呈冬季最高、夏季最低;福宁湾海域季度平均E值为1.48,水体已呈现富营养化状态;N/P〉16并不是福宁湾海域爆发赤潮的必要条件;福宁湾海域N/P值长期保持较高,秋、冬季N/P值较为稳定;PO4-P为福宁湾海域浮游植物生长营养盐限制因子.

| Abstract: | Based on the investigation from 2002 to 2003 in Funin Bay,temporal and spatial variation characteristics of active phosphorus and inorganic nitrogen, status in quo of nutrition and limitative factors of nutrition were studied.The results showed that the contents of PO_4-P and DIN were highest in winter and lowest in summer.The evalue of seasonly average in Funin Bay was equal to 1.48.The water in Funin Bay was eutrophied.N/P ratio exceeds 16 that isn't a necessary condition of breaking out red tide.N/P ratio keeps high for a long time.N/P ratio is steadier in autumn and winter than in spring and summer.PO_4-P is the limitative factor of nutrition of the growth of phytoplankton in Funin Bay. |
