| 摘 要： | 桑沟湾营养现状调查结果表明，桑沟湾营养状况不仅受沿岸排放水的影响，而且大面积的海带和扇贝养殖对于营养盐的补充与消耗也有较大的影响，特别是在扇贝养殖区水域，富营养化水平较高。由Ｎ／Ｐ比值计算结果表明，从整个海湾看，冬季无机氮显得相对紧缺，而其他季节无机磷则显得相对紧缺。但从局部海域看，各季节扇贝养殖区无机磷显得相对紧缺。而在扇贝和海带混养区的１月，以及在海带单养区养殖海带期间的１月和４月无机氮显得相

| Abstract: | This paper presents results of study on the nutrient state of aquaculture waters in Sanggou Bay showing that its nutrients state is affected not only by drain water from along the coast,but also by the large area culture of laminaria,and that the eutrophication level here was high,in the scallop culture region especially,But for the whole Sanggou Bay,inorganic nitrogen seems insufficient in winter,and inorganic phosphorous seems insufficient in other seasons. Inorganic nitrogen seems insufficient in the scallop-and-laminaria mix culture region in January and the laminaria culture region in January and April. Inorganic phosphorus seems insufficient in other months. |
