摘　　要：该文将目前国内主要河流、湖泊底泥的重金属污染状况进行了归纳整理,概述了底泥重金属污染的成因,指出了底泥重金属污染已成为水质重要的内源污染并对其带来的危害进行了描述。同时介绍了底泥重金属污染的两种主要修复技术:原位修复技术与异位修复技术。重点介绍了原位修复技术分为物理修复、化学修复及生物修复三种修复方式,详述了三种修复方式,包括各修复方式的修复原理、适用条件及其修复效果。最后展望了底泥重金属污染原位修复技术的应用与发展,指出在日益恶化、污染环境复杂的背景下物理、化学、生物的联合修复是目前原位修复最为环保、高效的修复方式。The cause of the sediments with heavy metal pollution was concluded in this paper, which pointed out that the sediment of heavy metal pollution has become an important endogenous pollution to water quality and described its damage with the situation of sediments of heavy metal pollution about the present domestic major rivers and lakes. At the same time, two major repaired technologies of sediments with heavy metal pollution： in-situ remediation technology and ex-situ remediation technology were described. The in-situ remediation technology was introduced and descripted as a key, and the in-situ remediation technology was divided into three remediation methods： physical remediation, chemical remediation and bioremediation. The description of three remediation methods was detailed, including the application condition and its repair effect, especially the principle of remediation. Finally, with the development prospect of remediation technology, combination of physical, chemical and biological repair is the most environmental and efficient remediation technology with the deterioration of the environment.
