| 摘 要： | 为了揭示三峡库区消落区不同垂直高程土壤重金属污染状况，笔者通过对三峡库区消落带不同垂直高程（145~155、155~165、165~175 m）土壤样品的分析，结果表明三峡库区消落带土壤重金属污染以As、Cd为主，Hg、Pb污染程度相对轻微。从长寿到巴东，即从库区的上游到下游，重金属含量普遍呈下降趋势。综合评价结果表明：三峡库区9个区县消落带中，除涪陵的3个垂直高程土壤重金属超过背景值，处于轻度污染状态，其余区县的3个垂直高程土壤重金属处于警戒线以下，土壤未受污染。总体来说，长寿、涪陵地区消落带土壤受重金属污染，控制污染源是防止消落带土壤重金属含量增加的有效方法。 |

| Abstract: | In order to reveal situation of heavy metal pollution from various vertical heights in water flooding fluctuation zone of Three Gorges reservoir areas,soil samples investigated from various vertical heights including 145-155,155-165 and 165-175 m in water flooding fluctuation zone of Three Gorges reservoir areas were analyzed,which indicated that soil heavy metal pollutions mainly were caused by arsenic (As) and cadmium (Cd) in comparison with mercury (Hg) and lead (Pb) pollution due to relatively lower con... |
