| 摘 要： | 湿地作为地球上重要的生态系统之一,具有稳定环境、物种基因保护及资源利用功能,被誉为自然之肾、生物基因库和人类摇篮。随着近年来湿地面临着面积萎缩、功能下降、污染日趋严重等危机,国内外学者对湿地保持着持续关注与研究,其中对湿地重金属的污染评价就是湿地科学研究领域的重要内容之一。笔者通过对国内十多年来有关重金属污染方面的报道进行整理分析,回顾总结了湖泊、河流、三角洲以及滨海等类型湿地的底泥、水体及土壤中重金属的污染现状与迁移特征,重点对重金属的种类、空间分布以及分析方法等进行总结归纳。在众多研究成果中,对污染物评价的方法以地累积指数法和潜在生态风险指数法使用最多。

Evaluation of Heavy Metal Pollution in Wetland: Research Progress in China |
| |
| Abstract: | As a kind of important human living environment and ecological system on the earth, the wetland plays an important role in stabilizing environment, protecting species gene and utilizing resources. The wetland is known as the cradle and biological gene pool of nature and human. With more and more serious wetland reduction, functional decline and pollution, domestic and foreign scholars focus their research on wetland continuously, and heavy metal pollution and assessment is one of the key research fields. The author analyzed domestic reports on heavy metal pollution in more than a decade, reviewed present pollution situation and migration characteristics of heavy metals in sediment, water, and soil such as lake, river, delta and coastal wetlands, and summarized the research types, spatial distribution of heavy metal and analysis method, etc. In many research achievements, the mostly used methods were the cumulative index method and potential ecological risk index method. |
