| 摘 要： | 根据1995年的调查资料，概述了廉州湾沿岸海域营养盐的分布特征及与水化因子之间的关系。以化学耗氧量（COD）、无机磷（P）、无机氮（N）为评价指标，分析评价了该湾的富营养化程度，指出该湾赤潮形成的主要因素是陆源营养物质的排人，通过N／P值，表明了N是该湾初级生产力的主要限制因子。

| Abstract: | The distribution characteristics of nutrient salt and its relation with water chemical factors in the Lianzhou Bay waters are analyzed based on the data in 1995.The eutrophication level of the bay is evaluated using COD, inorganic phosphorus and inorganic nitrogen as evaluation indexes. It is pointed out that the inflow of land nutrient is the main cause of red tide formation. The N/P ratio shows that inorganic nitrogen is the main factor to confine the primary productivity in the bay. |
