摘  要:
对不同水动力条件下上覆水体中总磷(TP)、可溶性正磷酸盐以及总氮(TN)的释放规律进行了研究。结果表明,徒骇河沉积物中TP的释放随着水体扰动强度的增强而增强,呈现一定的正相关关系;沉积物中可溶性正磷酸盐在释放过程中存在一个最适扰动强度,转速增强或减弱释放均减弱;而TN在一定扰动强度内,不受扰动时的释放强度比扰动时要大。

摘  要:
According to the study of the release of overlying water in total phosphorus(TP),solubility orthophosphate and total nitrogen(TN) in different hydrodynamic conditions,the results showed that: TuHai River sediments in the release of TP would increase with water perturbation strength,basically positively related.There was an optimal perturbation strength in the process of release of solubility orthophosphate in sediments.Then the revolving speed increased or decreased,the release of those above will diminishing.During certain perturbation strength,the release of TN will be more when without perturbation than with it.
