摘　　要：通过1998年6月对广东省红海湾海水养殖水域环境因子的调查,阐述了海水中溶解氧、盐度、pH值和营养盐的分布特征及其变化规律并讨论了它们之间的相互关系,结果表明,溶解氧及海水pH值随温度由北(除15～17号站)向南(除6号站)增高而增高.同时证实了光合作用是导致溶解氧含量和pH值增高的主要原因.而营养盐与盐度呈密切的负相关.浮游植物总量随营养盐由北向南降低而明显增高.In this paper the enviroumental factors are surveyed of the marine culture waters of the Hong Hai Bay at the end of the spring to early summer (6 month) in 1998. The distribution feature and variation law of dissolved oxygen, salinity, pH and nutrition salts in the sea water are expouned. Also discussed are their relationship between each other. The results show that the contents of dissolved oxygen and pH in the sea water increase with the increaseing temperature from north (except for No. 15 -17 stations ) to south (except for No.6 station). At the same time it is affirmed that photosynthesis is the major cause of the high content of dissolved oxygen and pH. And the nutrient shows a negative correlation with salinity. The total content of phytoplankton obviously increases with the reduction of nutrient from north to south.
