| 摘 要： | 通过对＂三峡库区响水滩等7幅1∶5万区域地质多目标调查＂取得的土壤元素进行分析统计,对比国内土壤元素和重庆沿江土壤元素含量数据,结果表明：调查区大多数元素含量处于正常水平,而Cd、Zr元素含量较高,Mo、Br、I偏低;通过对54项元素及指标相关性分析,发现部分元素如Sc-V、Fe-Ga、Nb-Ti、Sr-Na、Br-I、F-Li等元素对具有较强的相关性,而Ag、Au、Hg等较为分散;通过对每个地层的元素含量统计揭示出各种元素在各个地层单元中的分布特征。

| Abstract: | By studying the soil samples from multi-objective survey areas in Three-Gorges Reservoir Region and comparing domestic soil elements content and soil elements content along the Yangtze River in Chongqing,the result showed that most elements in survey area were at normal levels when compared to national background,while Cd,Zr were higher and Mo,Br,I were lower;the cluster analysis of the elements indicated that elements like Sc-V,Fe-Ga,Nb-Ti,Sr-Na,Br-I,F-Li had the negative correlation;the statistics analysi... |
