| 摘 要： | 通过实验室模拟试验,以富营养化湖泊-乌梁素海沉积物为试验材料,模拟了在零外源污染状态下沉积物中营养盐的释放特征,揭示了沉积物中TN、TP的释放规律和过程,量化了营养盐的释放速率.试验结果显示,在无扰动的静态水力条件下,沉积物中营养盐在向上覆水体的释放过程中,伴随着解吸-平衡的动态过程,其中TP的释放量是调控水体富营养化...

| Abstract: | A laboratory test was carried out on modelling the release processes of nutrients from the sediment of contaminated water bodies.The sediment was sampled from Lake Wuliangsuhai,which had been highly eutrophicated.The work revealed the release processes and characteristic nutrients from the sediment,and quantified the release rates.The results showed that at static state of water bodies the release processes were accompanied by dynamic transport processes.TP was the key element in controlling the eutrophicat... |
