摘　　要： 根据2001年7月～2002年7月间对柘林湾进行的溶解氧和营养盐含量的调查数据,探讨柘林湾海域溶解氧的时空分布规律及其与营养盐之间的相关关系.结果表明柘林湾的溶解氧含量年均值为5.88mg/dm^3,呈河口、湾外高,湾内低的平面分布规律.回归分析表明,柘林湾溶解氧含量与NO3-N含量呈显著的正相关关系,与PO4-P、NH3-N含量呈显著的负相关关系.大规模的养殖生产是影响柘林湾水体DO含量的一个重要因素. Based on the surveying data of dissolved oxygen （DO） and nutrients in Zhclin Bay from July 2001 to July 2002, spatial and temporal distributions and its relationship with nutrients were discussed. The result showed that the annual average of DO is 5.88 mg/dm^3. The contents in estuaries and outer bay were higher than inner bay. There was positive correlation between DO and NO3-N and a much significant inverse correlation was found between DO and PO4-P, DO and NH4-N. One of important factors influencing DO was the large-scale maricuhure in Zhelin Bay.
