摘　　要：河道是水的主要承载体,河道底泥作为河道的重要组成部分,对整个河道的污染状态起决定性作用。因此,文章以潮白河流域为例,研究了河道底泥污染和释放特征,并对发展趋势进行了分析。通过分析底泥的组成、来源、污染特征以及释放机制,为河道污染的评估和监测提供科学依据。在外源污染得到有效控制的基础上,研究提出了采用生态清淤疏浚方式来快速减小内源污染的方法。最终,根据评价及实验结果,揭示了底泥对上覆水体的影响,并提出了科学的生态清淤方案。通过深入研究河道底泥污染和释放特征,文章为环境保护、生态恢复和人类健康提供了科学支持,为保护水环境、维护生态平衡和保障人类健康提供了有效的管理和决策依据。The river is the main carrier of water,and the sediment of the river,as an important component of the river,plays a decisive role in the pollution status of the entire river.This article takes the Chaobai River Basin as an example to study the pollution and release characteristics of riverbed sediment,and analyzes its development trend.By analyzing the composition,source,pollution characteristics,and release mechanism of sediment,scientific basis is provided for the assessment and monitoring of river pollution.On the basis of effective control of external pollution,this study proposes a method of using ecological dredging to quickly reduce internal pollution.Finally,based on the evaluation and experimental results,the impact of sediment on the overlying water body was revealed,and a scientific ecological dredging plan was proposed.Through in-depth research on the pollution and release characteristics of river sediment,this article provides scientific support for environmental protection,ecological restoration,and human health,and provides effective management and decision-making basis for protecting water environment,maintaining ecological balance,and ensuring human health.
