摘　　要：重金属污染是当前重点关注的环境问题之一,重金属生态风险评价是污染生态学的有效方法和手段之一。综述目前国内外常用的4种沉积物重金属污染生态风险评价方法,包括单因子污染指数法、地累积指数法、潜在生态危害指数法、尼梅罗综合指数法,比较各方法的优缺点和适用性,指出根据研究目的和污染特性选择适当的评价方法。Heavy metal pollution is one of the current focuses on environmental issues, and the ecological risk assessment of heavy metals is one of the most effective methods in pollution ecology. The paper summarized four common methods of environmental risk assessment of heavy metals in sediments adopted at home and abroad, including Single index method, geoaccumulation index method, potential ecological hazard index method, Nemerow index method, made a comparative study on advantages and disadvantages and practicability of methods, pointed out the suitable assessment method according to the goal of study and the pollution characteristic.
