中国人. 选择合肥市不同功能区及不同母质上发育的20个水稻土剖面,分析Cd、Hg、Pb、As、Cu和Ni等重金属元素的剖面分布特征。结果表明,工业岗（圩）区、农业岗（圩）区水稻土剖面表层土壤Hg、Cd元素含量均值有显著差异,Cd、Hg、Pb在表层土壤中富集明显,向下迁移能力较差;工业岗（圩）区Cu、Ni元素在表层土壤中略有累积,As、Cu、Ni含量的剖面分布特征在工业岗（圩）区、农业岗（圩）区差异不显著,土壤中TFe2O3含量和地下水位是控制土壤剖面中As、Cu、Ni元素分布的重要因素。[著者文摘]

Twenty paddy soil profiles from Hefei, Anhui Province in industrial and agricultural environment, developed on different weathered parent materials and impacted under different environment, were chosen to study the profile distribution of heavy metals （ Cd, Hg, Pb, As, Cu and Ni）. The average value difference of Cd, Hg in the topsoils was remarkable. Cd, Hg and Pb accumulated in the topsoil obviously, and moved down to deep soil weakly. Light accumulations of Cu and Ni in the topsoil were found in the industrial environment. The, distributions of As, Cu, and Ni had little difference in the different profiles. TFe2 O3 content and water level impacted the migration of the As, Cu, Ni elements in the paddy soil profile.
