| 摘 要： | 对南四湖不同湖区的20个表层底泥样品的营养盐浓度做了实验分析,结果表明:南阳湖的总磷最高,独日湖次之;独山湖的总有机碳和总氮含量最高,南阳湖次之;而昭阳湖的总有机碳、总氮和总磷含量为最低。显然,南阳湖和独山湖两个湖区显示出一定程度的营养盐污染。表层底泥总氮与土覆表层湖水的总氮相关程度不高,其原因是该湖水中的总氮主要是无机氮含量;而底泥中的总氮主要是有机氮。而表层底泥总磷与土覆表层湖水的总磷含量相关程序很高。这表明南四湖底泥与湖水中的总磷在其来源和迁移转化途径上是相同的,即是湖水中的总磷主要是由流域内工农业及生活污水排放带来的,并在底泥中沉积和积累。 |
| 关 键 词： | 南四湖 表层底泥 营养盐 |

| Abstract: | The nutrient concentrations in the surface sediment of Lake Nansihu were obtained at 20 locations. this was performed to determine the pollution degree and spatial distribution of nutrients in different areas of Lake Nansihu. The results show that sediments from Lake Nanyanghu had significantly higher TP concentrations than any other area of Lake Nansihu. Lake Dushanhu suffered from the worst TOC and TN contamination. Lake Zhaoyanghu had low TOC, TN and TP concentrations. The correlation between the TN contents in lake water and its surface sediment is low because the TN in the lake water was mainly inorganic nitrogen but the TN in the surface sediment was mainly ogranic nitrogen. The correlation between the TP contents in lake water and its surface sediment is good, which indicates that the TP in the lake water and its surface sediment had the same source and transfer approach. |
