摘　　要：水体沉积泥沙质量不仅对底栖生物具有影响 ,而且由于泥沙与上覆水体相互间频繁的交换作用 ,泥沙质量与水体水质也有着密切的关系 ,污染的泥沙往往会成为水域的潜在污染源。因此 ,泥沙质量的评价对水环境保护具有重要意义。同时 ,利用泥沙质量评价水环境质量比利用水质评价具有一定的优越性。本文介绍了国际上常用的泥沙质量评价方法 ,并列出几种具有代表性的泥沙质量标准。通过一定的比较 ,推荐暂以美国的NOAA或FDEP泥沙质量标准来进行我国水体泥沙质量的评价。Sediment quality in waters not only affect the benthic organism, but also has close relation with the water quality due to the frequent pollutant interchanges between the sediment and overlaying water. The polluted sediment often becomes the potential source to pollute waters. So it is very important to evaluate the sediment quality for the water environmental protection. Moreover, using the sediment samples to evaluate the water quality is much better than using the water samples. In this paper, the authors introduce the evaluation methods in common use for sediment quality and list several kinds of representative sediment quality standards. By comparison, the NOAA or FDEP sediment quality standards are recommended for evaluating the sediment quality in waters.
