摘　　要：对近年来国内湖泊、河流和滨海等的湿地重金属污染研究情况进行了回顾,重点对重金属的种类、含量、形态、存在形式、空间分布等进行介绍。污染物危害评价主要采用地积累指数、潜在生态危害系数和潜在生态风险指数法进行。对于重金属污染的植物修复技术进行了探讨,建议对湿地中本土生长的植物的重金属富集能力进行分析,经过筛选从而得到适合本地生长且重金属富集能力较强的富集植物,并对污染的治理等提出了建议。The domestic research progress of heavy metal pollution in wedand, incuding lake, river and coast was reviewed. The kind, content, form, existing form, space distribution, etc. of the heavy metal were introduced. The geoaccumulation index, the potential ecological risk coefficient and the potential ecological risk index were used to estimate the harm. The plant renovation was discussed too. The plants which could strongly enrich the heavy metals and grow natively were recommended, Some suggestions about the pollution harmless were given.
