摘要
土壤矿物和粒级组成及其与土壤元素关系的研究对土壤生态环境和肥力评价具有重要意义。对安徽铜陵地区土壤的研究发现,不同粒级段土壤中元素富集程度不同,不同元素的富集粒级也不尽相同,-200目细粒级中各种元素含量最低。研究表明,土壤不同粒级段的矿物组成不同,伊利石和针铁矿对Cu、Zn、Cd、Pb、As等元素具有较强的吸附作用。
The same element has different concentrations in different sizes of soft, and the enrichment of different elements is not the same in the same size of soil in Tongling area of Anhui Province. All elements have the lowest content in -200 mesh. Tests show that different sizes of soil have different mineral compositions. There exists strong positive correlation between minerals of illite and goethite and Cu, Zn, Cd, Pb, As, indicating that illite and goethite can strongly adsorb these elements.
