摘　　要：根据2013-2014年对三门湾17个站位的四期调查结果,与20世纪80年代的结果进行分析比较,讨论了沉积物中营养盐的含量及分布特征。结果表明,调查海区沉积物中总氮和总磷的含量较之前有所降低,说明了三门湾富营养化程度在降低。不同营养盐表现出了不同的年内变化特点,有机碳含量2月>5月>8月>11月,总氮含量8月>11月>5月>2月,总磷含量8月>5月>11月>2月。According to the 2012-2013 of Sanmen Bay at 17 stations in four survey results,and results of the 1980 s for comparative analysis,discusses the content and distribution of nutrients in sediments. The results show that the investigation of sediments in the sea area of total nitrogen and total phosphorus content compared to the previous decreased,indicating that the Sanmen Bay eutrophication degree is reducing. Different nutrients showed different characteristics in different years. The content of organic carbon was 〉5 months 〉8 months,〉 11 months, 〉11 months,total nitrogen content was 〉5 months, 〉2 months,months,total phosphorus content was 〉11 months 〉5 months months 〉2 months.
