摘　　要：通过对比金矿区水库底泥剖面与邻区水系沉积物重金属含量,评价了底泥中砷、铬、汞、铅、铜、锌等重金属的污染现状;结合剖面不同层位物理性状,分析了影响重金属富集的两个因素:一是沉积物自身的吸附作用,二是区域矿业活动的强弱。In this paper, by comparing the contents of heavy metals in the sediments profile of reservoirs in the gold mining area and in stream sediments of neighbour areas, the evaluations of pollution in the sediment by heavy metals including arsenic, chromium, mercury, lead, copper, zinc were finished. The two effecting factors on enrichment of heavy metals were analyzed with the physical properties of different sections and layers： one is adsorbent actions of sediment by itself, and the other is the strength of mining actions in these regions.
