| 摘要: |
| 通过系统测定鄱阳湖湖水、主要入湖口河水及部分农田水、地下水及城市污水氮磷含量,对其氮、磷污染状况进行了分析,同时对湖水及河水的氮、磷来源进行了初步讨论.结果表明,鄱阳湖区水体已达到一定程度的氮、磷污染,特别是饶河段氮含量较高(0.89-3.15mg/L),信江磷含量较高(0.098-0.22mg/L),而湖体的总氮、总磷含量也分别达到1.06±0.28mg/L和0.067±0.042mg/L,已具备富营养化的条件. |

| Abstract: |
| Based on the systematic measurment of nitrogen (N) and phosphorus (P) concentrations in lake water, the main river water,
partial agricultural drainage, groundwater and urban sewage, we analyzed the present situations of N and P pollution at the Lake
Poyang Basin, and discussed the sources of the pollution primarily. Lake Poyang Basin was polluted by N and P at some extent, while
especially Rao River was polluted by N seriously and Xin River was polluted by P badly. The concentrations of total nitrogen and
total phosphorus were 1.06±0.28mg/L and 0.067±0.042mg/L respectively in the Lake Poyang water and the lake has subjected to
eutrophication status. |
