【摘要】 文章分析了太原盆地土壤微量营养元素Fe、Mn、Cu、Zn、Mo、B和有害重金属元素As、Cd、Cr、Hg、Pb的含量变化特征。太原盆地土壤中微量营养元素与世界土壤和全国土壤的平均值相比趋于缺乏状态,而高于全国黄土和山西省土壤的平均含量。有害重金属元素在太原盆地表层土壤的富集已较明显,原有的地球化学特征已发生较大变化。Hg、Cd、Pb对环境的危害作用应引起重视。更多还原

【Abstract】 Based on analyzing the contents of trace nutritive elements of Fe, Mn, Cu, Zn, Mo and B and harmful heavy metallic elements of As, Cd, Cr, Hg and Pb in soils of the Taiyuan basin, It is pointed out the trace nutritive elements in soils of the Taiyuan basin are in lacking level compared with the average world and China’s soils, and higher than the average contents of the Shanxi province’s soils and Chinese loess. It has been also found that obvious enrichments of harmful heavy metal elements in top-soils of the Taiyuan basin, which could cause great changes of the original geochemical features of soils. Environmental damaging caused by Hg, Cd, Pb in the Taiyuan basin should be paid more attention.更多还原
