摘要：

本文报道了1999年12月—2000年3月期间南极长城站码头叶绿素a的含量及变化,调查期间叶绿素a含量较高,平均值为2.16mg/m3,变化范围为0.60—7.67mg/m3。高值出现在月初和月中,低值出现在月上旬,这是潮汐所至。而营养盐的含量较高且变化较大,但PO4P的含量较低,且变化不明显。营养盐的浓度由高到低依次为NO3N>NH4N>NO2N>PO4P。

Abstract:

The variations of chlorophyll a and nutrient contents were investigated at the wharf of the Great Wall Station between December 1999 and March 2000. The chlorophyll a contents were high during the investigation period. The values ranged from 0.603 to 7.667mg/m3 with an average of 2.162mg/m3. With the influence of tide, the highest values occurred both at the beginning and in the middle of months. The nutrient contents and variations were high except for PO_4-P. The order of the contents from high to low was NO_3-N>NH_4-N>NO_2-N>PO_4-P.
