| 摘 要： | 对红枫湖、百花湖水库沉积物及其磷储量的调查统计,结合近年来两湖频繁发生的水污染事件,研究了红枫湖、百花湖水库沉积物总磷含量分布及其总磷负荷对湖泊富营养化贡献,探讨了红枫湖、百花湖水库沉积物的释磷潜力。结果表明,红枫湖、百花湖沉积物中总磷含量分布由表层到底层进行递减堆积,沉积物已成为两湖近年来湖泊磷富营养化的内源。到2006年红枫湖、百花湖沉积物干重累积量分别为240.7万t、73.78万t,平均总磷含量为0.163%、0.174%,总磷储量已达3 924 t、1 284 t。当外界环境因素推动时,沉积物发生搅动造成磷大量释放,是两湖频繁发生湖泊大面积水华污染事件的主要原因。 |

| Abstract: | Base on the investigation statistics of sediment and its phosphorus reserves in Hongfeng and Baihua lake reservoirs,integrated with frequent water pollution in recent years,this article has discussed emphatically sediment total phosphorus burden of Hongfeng and Baihua lake reservoirs to its eutrophic contribution.The results indicated,started from the 1990's,phosphorus in sediment of Hongfeng and Baihua lakes is astonishing.The average values of total phosphorus in dry sediments are up to 0.163% and 0.174% ... |
