摘要
根据１９８７年６，８，１１月和１９８８年２月４个航次珠江口伶汀洋的调查资料，分析了溶解氧的特征。结果表明：溶解氧含量表层均高于底层，周年变化呈现从夏季到冬季逐渐上升，且明显受珠江径流的影响，溶解氧（基本上是不饱和状态）与盐度成负相关。有机物和营养盐均影响溶解氧，但水温仍为溶解氧主要影响因素。
he characteristics of dissolved oxygen (DO)has been analyzed based on four cruisesof investigated data in Lindingyang waters of the Zhujiang (Pearl River)estuary in June, August, November 1987 alld Februnary 1988, respectively. The results show that DOamount in surface water was higher than that in bottom water; annual variation of DOincreased gradually from summer to winter; and was apparently affected by the runoffof Zhujiang River; There was a negative correlation between DO, which was mostly undersaturated, and salinity. Organic matter and nutrients (N, P and Si) have influence onDO, but water temperature is still a major factor for DO.
