根据2008年2～11月对流沙湾海域4个航次的溶解氧和营养盐含量的调查数据，分析了表层海水中表观耗氧量的时空分布，并探讨它与营养盐之间的相互关系。结果表明：流沙湾冬春季海域表观耗氧量较大，而夏秋季表观产氧量较大；夏秋季大部分站位海水的溶解氧处于过饱和状态，其中秋季溶解氧的平均饱和率最高；表观耗氧量与溶解氧和溶解氧饱和率都呈现显著负相关，溶解氧和溶解氧饱和率呈显著正相关；表观耗氧量和营养盐根据不同的季节具有一定的相关性。流沙湾海域△CN／△CAOU，的比率为1：41．0，△Cp／ACAOU，的比率为1：588和1：303，均低于Redfield的理论比值。

According to the four seasonal surveying data of dissolved Oxygen and nutrients in Liusha Bay from Feb- ruary to November, 2008, the spatial and temporal distributions of apparent oxygen utilization in surface seawater were analyzed, and the relationship between apparent oxygen utilization and nutrients were discussed. The results showed that the apparent oxygen utilization in winter and spring was higher and the apparent oxygen production was higher in summer and autumn in Liusha Bay. Supersaturated dissolved oxygen appeared in autumn and summer at most of stations. The average saturation rate was the highest in autumn. The apparent oxygen utilization was signifi- cantly negatively correlated to the dissolved oxygen and dissolved oxygen saturation rate. The dissolved oxygen was significantly positively correlated to the dissolved oxygen saturation rate. The apparent oxygen utilization and nutri- ents were correlated to each other at different seasons. The ratio of △CN/△CAOU was 1：411 0 and that of △Cp/ACAOU was 1 ： 588 or 1 ： 303, being lower than Redfield theoretical ratio.
