摘　　要：根据20世纪60年代以来尤其是2000年后的胶州湾营养盐调查与研究资料,同时根据2013-2014年在胶州湾开展的14个航次的综合调查,研究近年营养盐的时空变化特征和限制的变化。结果表明,近10年胶州湾各项营养盐增加速率发生变化,氮磷比严重失衡。同时胶州湾营养盐结构与限制发生变化,营养盐由硅限制逐步转变为磷限制,磷为胶州湾的主要限制因子。Temporal and spatial variation characteristics and structural changes of nutrients were investigated in this study based on the data obtained from the Jiaozhou Bay ecosystem monitoring since 1960s, especially after 2000,and the comprehensive investigations of 14 voyages from 2013 to 2014.It was found that the increasing rate of nutrients in Jiaozhou Bay has changed in recent 10 years.The N/P ratio was seriously unbalanced.Nutrient structures also changed dramatically.The silicon limitation gradually shifted to phosphorus limitation.Phosphorus was the main limiting factor of Jiaozhou Bay.
