| 摘 要： | 采用校园水体底泥进行上覆水营养盐浓度对底泥释放量之间的关系研究。结果表明,在本实验条件下,上覆水水质影响底泥氮、磷的释放,尤其显著影响氮、磷的初期释放;上覆水氮、磷的浓度越小,底泥氮、磷的释放量越大;上覆水氮、磷的浓度超过一定值,会抑制底泥氮、磷的释放。

| Abstract: | This paper carried out the experiment on the relationship of nutrient salt concentration in overlying water and nitrogen and phosphorus release of sediment by using campus sediment. The experimental results show that nitrogen and phosphorus releases especially the initial release rate, is obviously affected by the quality of overlying water, the lower concentration of nitrogen and phosphorus of overlying water, the higher release amount of TN and TP of sediment, when the concentration of nitrogen and phosphorus of overlying water is higher than a certain value, nitrogen and phosphorus releasing would be restrained. |
