摘    要:通过同步监测表层沉积物和上覆水体氮磷浓度以及环境因子(pH值、温度、溶解氧等),利用回归分析方法,对溶解氧、表层沉积物有机质含量与上覆水体氮磷浓度之间的关系以及氮磷在表层沉积物和上覆水体间迁移规律进行探讨。结果表明,高水温、碱性环境有利于氮磷营养物质的释放;上覆水体氮磷浓度与溶解氧呈现显著非线性负相关关系,与表层沉积物中有机质含量呈现显著线性正相关关系,且冬季极显著;表层沉积物氮磷含量与上覆水体氮磷浓度呈现出互补的动态特征。

关 键 词:表层沉积物  上覆水体      迁移规律

Abstract:By monitoring simultaneously nitrogen phosphorus in the surface sediments and overlying water,environmental factors such as pH,temperature,dissolved oxygen and so on,a regression analysis is used to study the correlation between nitrogen phosphorus of overlying water and dissolved oxygen,organic matter content of the surface sediments.At the same time the migration rule of nitrogen phosphorus in the surface sediments and overlying water is studied.The results show that high temperature,alkaline environment ...
Keywords:surface sediment  overlying water  nitrogen  phosphorus  transport law
