摘要: 长江流域是一个贯通串联起我国西部、中部、东部的辽阔地域。在全球变化的大背景下,该地区工业化、城市化进程不断加快,由此引发的重金属污染问题愈来愈被人们所重视。本文分析了目前长江流域沉积物和土壤重金属污染的现状,以及长江流域沉积物和土壤重金属整体分布规律、分布特征以及污染来源,讨论了重金属的迁移规律、存在形态以及全球变化可能会对长江流域重金属分布造成的影响。在此基础上,提出目前长江流域沉积物和土壤重金属研究的不足,并对未来需要开展的研究工作进行展望。

Abstract: The Yangtze River Basin is a vast area connecting the western, central and eastern parts of China. In the context of global change, the industrialization and urbanization in this region are accelerating. Heavy metal pollution has been paid more and more attention. We summarized the current situation of heavy metal pollution in sediments and soils in the Yangtze River Basin, and the distribution pattern, characteristics of heavy metal pollution and sources of pollution. We discussed the migration patterns and existing forms of heavy metal and the possible effects of global changes on the distribution of heavy metals in the Yangtze River Basin. On this basis, we pointed out the deficiencies of current studies on heavy metals in sediments and soils of the Yangtze River Basin, and suggested a forecasting of future research.

Key words: sediment, soil, heavy metal pollution, global change, Yangtze River Basin.
