摘要
通过取样调查和实验分析,研究了西安市郊农田土壤环境的地球化学特征。土壤中的常量元素和微量元素结果分析显示,CaO、MgO和Na2O含量明显高于陕西土壤、全国土壤中的平均值,重金属元素Pb、Ni、Zn、Cr、Co、Mn、As等严重超标。通过相关分析和聚类分析,探讨了土壤元素间的亲和性及赋存特征,为农业生产、农业结构调整和防治土壤污染提供地球化学依据。
Based on systematic sampling and investigation of agricultural soil, the geochemistry characters of agriculture soil of Xi＇an city were studied. The results showed that the contents of CaO,MgO and Na2O were more than the averages of Shaanxi and Chinese, and the contents of the heavy metal elements such as Pb.Ni.Zn.Cr.Co.Mn and As were also beyond the limit. Through the study on geochemistry characters of. agriculture soil, we could supply the geochemical basis for agriculture production, agricultural restructuring and remediation of soil contamination.
