1993／1994年南极夏季对中国南极长城湾及附近海区表层海水四种营养盐浓度及其分布状况作了调查。结果表明，NH4－N、NO3－N、NO2－N及PO4－P的大致浓度分别是2．13、7．07、0．74和1．12μg·dm-3。一般来说，湾内高于湾外氮盐于12月份常出现高值。四种形态的无机盐类之最高、最低浓度出现的时间和站位不尽一致。∑N／P递减次序大致是12月，2月，1月。水温变化与NH4－N、PO4－P浓度和∑N／P的变化常较一致，而与NO2－N则常不一，一些站位上营养盐浓度偏低可能与浮游植物摄取有关。结果显示了调研海区的浅水内湾特征。浮游植物所需营养充分。该湾仍维持正常状态。

The 1993/94 summer Antarctic summer survey of four nutrient concentrations and their distribution in surface waters in the Great Wall and Antarctic waters of the Antarctic. The results showed that the approximate concentrations of NH4-N, NO3-N, NO2-N and PO4-P were 2.13, 7.07, 0.74 and 1.12 μg · dm-3, respectively. In general, nitrogen in the bay higher than that outside the bay often shows high value in December. Four kinds of inorganic salts of the highest, the lowest concentration of time and stations are not consistent. ΣN / P decreasing order is roughly December, February, January. The change of water temperature is consistent with the changes of NH4-N, PO4-P and ΣN / P, but not with NO2-N. The lower nutrient concentration in some stations may be related to phytoplankton uptake. The results show the shallow-water inner bay features of the study area. Phytoplankton required adequate nutrition. The Bay is still in its normal condition.
