摘要
本文根据1983年9月至1985年1月南海中部海域调查的资料,分析了该海区海水中铵浓度的频率分布、垂直分布特征和次表层铵最大值的形成及其与环境因子的关系。结果表明,铵浓度变化范围在0～2.71μmol/dm^3之间,铵含量小于0.5μmol/dm^3的样品数约为样品总数的78%,铵最大值出现在表层和次表层机率较大.文中还对该海域表层的铵含量与浮游植物的关系进行了初步探讨.
Based on the survey data of the central South China Sea from September 1983 to January1985,the frequency distribution and the vertical structure characteristics of ammonium con-centration and the relationship between the formation of subsurface ammonium maximumand enviromental factors are studied.It shows that the concentration of ammonium rangesfrom 0 to 2.71 μmol/dm^3,the samples containing less than 0.5 μmol/dm^3 accounting forabout 78% of the total sample,and the maximum ammonium occurs the surface or subsurfacein the spring.The relationship between surface ammonium content and the growth of phyto-plankton is primarily discussed in the study.
