摘　　要：沉积物是湖泊的重要组成部分,是水体重金属的源与汇。文中重点介绍了国内湖泊水体沉积物重金属污染概况及其成因,以及对水生态系统造成的影响与对人体健康的危害。阐述了沉积物重金属污染常用的评价方法,并分析了各自的优缺点。论述了对沉积物重金属污染修复的相关研究方法及其适用范围。继而展望了沉积物重金属污染的研究方向。Sediment is an important part of lake system, and usually considered as a sink and source for heavy metals of water body. The status and properties of heavy metal contamination in sediment of lakes in China were introduced in details, as well as the causes of sediment heavy metal contamination. The impacts on the safety of aquatic ecosystems and human health by heavy metals contamination were presented. Subsequently, several favorite risk assessment methods of heavy metals in sediment were summarized and the respective advantages and disadvantages of these methods, were analysed. Moreover, the relevant remediation methods of sediment contaminated with heavy metals and their application scopes were described. Finally, the future directions relating to heavy metal contamination of lake sediment were discussed.
