【摘要】 在综合调查的基础上，对１９９７ 年１０ 月胶州湾的营养盐分布作了较详尽的分析。湾内各营养盐硝酸氮、亚硝酸氮、氨氮、磷酸盐及硅酸盐的含量分别为２．７３～１４．７１、０．６１～３．２１、３．３１～３４．５５、０．２６～２．０５、４．４７～１５．８６μｍ ｏｌ／Ｌ，其中表层含量低于底层，湾内明显高于湾外，此次调查结果比往年略有提高。ＴＩＮ／Ｐ在２０～３０ 之间，表层平均为２６．３，底层平均为２５．４。并探讨营养盐分布的基本特征及影响因子，对胶州湾口的两个断面分析为研究胶州湾内外水团交换作了较好的基础工作。更多还原

【Abstract】 Detailed analyses on the horizontal and vertical distributions of nutrients in Jiaozhou Bay are presented in this paper, based on the investigation in October 1997. The ranges of nitrate, nitrite, ammonia, phosphate and silicate are 2.73~14.71μmol L -1 , 0.61~3.21μmol/L, 3.31~34.55μmol/L, 0.26~2.05μmol/L and 4.47~ 15.86 μmol/L, respectively. Nutrients contents are lower in the surface water than those near the bottom, and those inside the Bay are higher than outside. All nutrients show slightly higher contents compared to their former values. The TIN/P ratio ranges from 20 to 30 with a value of 26.3 in the surface and 25.4 at the bottom. Reasonable and detailed discussions are also made about the formation of this distribution and its influential factors.更多还原
