广东省阳江-茂名地区土壤地球化学背景值与基准值分析

Analysis of soil geochemical background values and reference values in Yangjiang Maoming area of Guangdong Province

基于阳江茂名地区多目标地球化学调查数据资料,获得了表层和深层土壤地球化学基准值、背景值。研究表明,阳江—茂名地区土壤富集Se、Sn、Th、Zr、B、U,贫乏Zn、Sb、Cr、Cu、Mn、Ni、Sr、MgO、Na_2O、CaO,表层土壤化学组成表现出既对深层土壤具有一定的继承性,同时又在表生作用下,富集土壤中生物元素和环境元素,如OrgC、S、Hg、Bi、P、Y等。

Based on the data of multi-target geochemical survey in Maoming area of Yangjiang,geochemical and surface values of surface and deep soil are obtained.The soil enriched Se,Sn,Th,Zr,B,U,poor Zn,Sb,Cr,Cu,Mn,Ni,Cu,Mn,surface soil chemical composition showed a certain inheritance to the deep soil,and enriched the biological elements and environmental elements in the soil under the effect of epigenetic action.S,Hg,Bi,P,Y and so on.
