烏蘭呼都格地區(qū)戈壁化草原地球化學(xué)特征及異常評(píng)價(jià)摘要：本文通過(guò)采集烏蘭呼都格地區(qū)戈壁化草原不同深度土壤，對(duì)其地球化學(xué)特征進(jìn)行研究，并對(duì)地球化學(xué)異常進(jìn)行評(píng)價(jià)。結(jié)果表明，土壤中主量元素含量依次為Si、Al、Fe、Ca、Mg、K、Na，微量元素含量依次為Ti、Mn、V、Ni、Cr、Co、Cu、Zn、As。其中Si和Al富集在粘土礦物中，F(xiàn)e和Mn主要富集在氧化物中。土壤Ba、As、Pb、Zn等微量元素含量較高，其中As、Pb超過(guò)生態(tài)標(biāo)準(zhǔn)。評(píng)價(jià)結(jié)果表明，本區(qū)土壤Zn異常較為顯著，As、Pb、Cu等微量元素可能存在環(huán)境風(fēng)險(xiǎn)。

Abstract:Inthispaper,thegeochemicalcharacteristicsofsoilinthedesertifiedgrasslandofWulanHUDUGeareawerestudiedbycollectingsoilsamplesfromdifferentdepths,andthegeochemicalanomalieswereevaluated.TheresultsshowedthatthecontentofmajorelementsinthesoilwasSi>Al>Fe>Ca>Mg>K>Na,andthecontentoftraceelementswasTi>Mn>V>Ni>Cr>Co>Cu>Zn>As.SiandAlwereenrichedintheclayminerals,whileFeandMnweremainlyenrichedintheoxides.ThecontentsofBa,As,Pb,Znandothertraceelementswererelativelyhigh,amongwhichAsandPbexceededtheecologicalstandards.TheevaluationresultsshowedthatsoilZnanomalywasmoresignificantinthisarea,andtraceelementssuchasAs,PbandCumighthaveenvironmentalrisks.
