海水中的无机氮是浮游植物生长必需的营养要素之一,是海洋生物食物链中基础的一环,其含量的变化将会对海洋生物的生态平衡和海域初级生产力产生直接影响。因此,研究潮间带养殖区海水中无机氮含量的分布和变化及其与物理、化学、生物诸因素之间的关系,对于“海洋水产生产农牧化”研究的重要性是毋容置疑的。本文根据1981年1月至1983年10月对围头湾潮间带养殖区牡蛎死因调查中所得的理化环境资料,主要对围头湾潮间带养殖区海水中无机氮含量分布和季节变化以及物理、
Inorganic nitrogen in seawater is one of the essential nutrients for the growth of phytoplankton. It is one of the basic elements in the marine food chain. The change of its content will have a direct impact on the ecological balance of marine organisms and the primary productivity of marine waters. Therefore, the study of the distribution and changes of inorganic nitrogen in the seawater in the tidal zone and its relationship with the physical, chemical and biological factors is of undoubted importance in the study of “marine aquaculture production and agriculture and animal husbandry” . Based on the data of physical and chemical environment obtained from the investigation of the cause of death of oyster in the intertidal zone of Wentou Bay from January 1981 to October 1983, the distribution and seasonal variation of inorganic nitrogen in the seawater in the intertidal zone of Wentou Bay were analyzed. physical,
