| 摘 要： | 以关中东部全新世黄土-古土壤剖面为研究对象,分析了Ni、Mn、Cu、Zn、Nb、As、Ti、V、Co和Pb十种土壤重金属元素的含量及其分布特征,并与磁化率、Rb/Sr曲线进行了比对和相关性分析,研究结果表明:Ni、Cu、As、V、Mn、Zn和Nb重金属元素的动态变化与全新世以来成壤环境的变化趋势是一致的,暗示全新世土壤...

| Abstract: | Based on the Holocene loess-soil profile in eastern Guanzhong,we analyzed the content and distribution of Ni,Mn,Cu,Zn,Nb,As,Ti,V,Co and Pb at TSG site and compared with magnetic susceptibility and Rb/Sr.The results showed that the changes of Ni,Cu,As,V,Mn,Zn and Nb were affected by climate change and its pedogenesis environment,Co was contacted closely with soil parent materials,and the sensitivity of Pb into its pedogenesis environment was poor.In the stage of paleosol period in eastern Guanzhong,the conte... |
