摘　　要：采用现场调查和实验室模拟研究的方法对胶州湾水域春季NH4-N吸附量、硝化效率、平均硝化速率与颗粒物的关系以及硝化作用对NH4-N的周转时间进行了研究。结果表明，胶州湾硝化作用对NH4-N的周转时间为0．10～3．33d，平均1．65d，且存在中西部和湾口附近海域周转时间短，在湾的东北部海域周转时间长的分布特征。The adsorption amount of ammonia, nitrification efficiency and average rate of nitrification, and the relationship between the particulate matters and turnover time of ammonia were studied by the method of on-site investigation and laboratory simulation in spring in Jiaozhou Bay. The results showed that the turnover time of ammonia by nitrification is 0.10 - 3.33d with an average of 1.65d in Jiaozhou Bay. The turnover times in the Western and the near bay mouth area were shorter than in else area. The turnover time is the longest in the northeast area in Jiaozhou Bay.
