| 摘 要： | 以超额磷负荷为评价指标,计算武汉东湖底质中磷的可释放量为439.4t,底质磷释放实验表明其释放速率为9.47mg/m2·d。东湖底质磷释放对水体磷水平的贡献达到25%。预测在无新外源输入条件下,其内源污染仍会使水体在近20年内保持高的磷水平。

| Abstract: | The quantity of phosphorus that can release to water in sediment of East Lake, Wuhan is 439.4t with the excessive loading of phosphorus as assessment index. Determination about the release of phosphorus in sediment showed that the rate of P release is 9.47mg/m2·d. The proportion of phosphorus in water sourcing sediment reaches to 25%. Internal loading of phosphorus would maintain higher level of P in water in 20 years without any external loading. |
