| 淤积问题对我国的水利事业影响深远，而底泥清淤是近些年淤积治理中经常采用的措施。针对底泥清淤的现状和存在问题，系统梳理了底泥清淤这一学科交叉领域的相关理论、技术和方法;阐述了对底泥清淤的概念、内涵、类型及基本问题的科学理解;提出了淤积治理中底泥清淤必须明确的四大问题：为什么治理、治理什么、用什么方法治理以及对后续产物如何处置。依据淤积对河湖库产生的危害，可分为物理性淤积、化学性污染和生态性损害三种类型。分别讨论了工程清淤、环保清淤和生态清淤间的共性和差异。对底泥清淤工程在目的、目标、手段及后续处理处置方面的现状及存在问题进行了评述。未来底泥清淤势必成为一个长期存在的工程和管理行为，因此更加高效、低投入、绿色、可持续的底泥清淤技术，是行业必然的发展方向。 |

| The siltation problem has a far-reaching impact on China’s water conservancy，and sediment dredging is a frequently adopted measure in siltation management in recent years.In view of the current situation and problems of sediment desilting，the relevant theories，technologies and methods in the interdisciplinary field of sediment desilting are systematically sorted out;the scientific understanding of the concepts，connotations，types and basic problems of sediment desilting are elaborated;and four major problems that must be clarified in sediment desilting are put forward:Why Remediate，What to Remediate，Which Methods to Use，and What to do with Treated Sediments.Considering the hazards of siltation on rivers，lakes，and reservoirs，the article categorizes these into three types:physical siltation，chemical pollution，and ecological damage.It delves into the commonalities and distinctions between engineering desilting，environmental protection desilting，and ecological desilting.The current state and challenges of siltation control engineering are then reviewed with respect to purpose，objectives，means，and subsequent treatment and disposal.Looking ahead，sediment dredging is poised to be a long-term engineering and management endeavor，making the pursuit of more efficient，low-input，green，and sustainable technology an inevitable industry development direction. |
