| 摘 要： | [目的]研究三峡库区不同地域土壤中微量元素分布与空间变异性。[方法]对三峡库区重庆段中下游的万州区、开县、忠县、城口县、奉节县、丰都县、云阳县7个县市土壤中的Fe、Mn、Zn、Cu等4种微量元素含量进行测定与分析。[结果]研究结果表明,重庆万州区、云阳县属于缺Fe、Mn、Zn亚区,开县属于富Fe缺Zn亚区,丰都县、忠县属于缺Zn亚区,奉节县属于缺Cu亚区,城口县属于富Fe、Mn,缺Zn亚区。[结论]三峡库区重庆段中下游土壤中Fe、Mn、Zn、Cu含量分布不均匀。

| Abstract: | [Objective] The research aimed to study the trace element Fe,Mn,Zn,Cu distribution and spatial variability of different soil in the Three Gorges reservoir area.[Method] The concentrations of 4 kinds trace elements Fe,Mn,Zn,Cu in Chongqing section middle and lower reaches 7 counties Wanzhou District,Kai County,Zhong County,Chengkou County,Fengjie County,Fengdu County,Yunyang County of Three Gorges reservoir area were measured and analyzed.[Result] The results showed that Wanzhou District and Yunyang County was subregion lacking,Fe,Mn,Zn.Kai County was subregion rich of Fe,lacking Zn.Fengdu County and Zhong County was subregion lacking Zn.Fengjie County was subregion lacking Cu.Chengkou County was subregion rich of Fe and Mn,lacking Zn.[Conclusion] The concentrations distribution of 4 kinds trace elements Fe,Mn,Zn,Cu in Chongqing section middle and lower reaches of Three Gorges reservoir area was uneven. |
