摘    要:根据1998年1月、4月、8月、10月4个航次的调查资料,分析廉州湾海水营养盐组成特征并用回归方法分析营养盐含量与主要环境因子的关系。结果表明,营养盐随季节不同而发生变化,丰水季节,营养盐组成Si:N:P比例明显偏高,枯水季节,营养盐组成比例明显偏低,影响这一特征变化的主要原因是与注入该湾的径流量和污染物有关。无机氮、无机磷、活性硅酸盐与主要环境因子具有明显的相关性,且相关程度随季节不同而发生差异。

关 键 词:海水  营养盐  组成特征  环境因子  相互关系

Abstract:Four voyages of investigations on the characteristics of the nutrient salts in the seawaters of Lianzhou Bay were carried out in January,April,August and October of 1998 The regression analysis was used to probe into the relationship between the contents of nutrient salts and the main environmental factors The results showed that the composition of nutrient salts varied in different seasons The ratio of Si to N to P was going up in the high discharge term,and going down in the low discharge term These are mainly related to the river runoff and pollutant intake in the Lianzhou Bay There existed correlations between inorganic nitrogen,inorganic phosphorus,active silicate and the environmental factors,and the correlations were different in different seasons
Keywords:seawater  nutrient salts  composition characteristics  environmental factors  correlation
