摘　　要：随着经济的快速发展,水体沉积物中的重金属污染越来越严重,对于重金属污染的研究也成为热点。对于水体沉积物中的重金属污染的评价方法有很多种,本文主要介绍了水体沉积物重金属污染评价具有代表性的方法,包括综合污染指数法、地累积指数法、潜在生态危害指数法、生物效应浓度法、沉积物富集系数法、尼梅罗综合污染指数法。以上方法各有优点和不足,在实际应用评价的过程中,应尽可能地采用多种方法相结合的方式对重金属污染进行评价,使评价结果更加准确,具有可信度。With the rapid development of economy,heavy metal pollution in water sediments is becoming more and more serious. Therefore,study on heavy metal pollution evaluation becomes a hot topic. There are manykinds of evaluation methods about heavy metal pollution including comprehensivemethods of pollution assessment, method of geoaccumulation index, potentialecological risk index method, biological effect concentration method, and Nemerowcomprehensive pollution index method. Each method has advantages anddisadvantages. In the process of practical application evaluation, multiplemethods should be used to evaluate heavy metal pollution as much as possible,so as to make the evaluation result more accurate and reliable.
