摘要:
以博尔塔拉河沿岸表层土壤中重金属As，Cd，Ni，Cr，Pb与有机质及pH为研究对象，并对它们之间关系进行研究。结果表明：土壤中5种重金属元素As，Cd，Ni，Cr，Pb平均含量分别为22.37，52.52，27.50，0.48，28.92 mg/kg。土壤有机质平均含量为27 431 mg/kg。土壤pH值为6.5～7.5，平均值为6.94。研究区土壤性质与土壤重金属含量间关系复杂：有机质含量与As，Cd，Cr，Pb含量呈显著正相关，有机质易与重金属离子形成络合物，从而降低重金属离子活性，导致土壤重金属含量增加；pH值与As，Cd，Pb含量之间呈显著负相关，随pH值增大，有效态As、有效态Cd和有效态Pb在土壤中含量明显减少。通过对土壤有机质、pH与重金属含量的关系研究，发现土壤有机质、pH是影响土壤重金属含量的重要因素。
Abstract:
As, Cd, Ni, Cr, Pb, organic matter and pH were monitored in the surface soil of the Bortala River. The correlation of five kinds of heavy metals: As， Cd， Ni， Cr， Pb in surface soil in the studied area and the soil organic matter and pH value was analyzed. The results show that average contents of 5 kinds of soil heavy metals such as As, Cd, Ni, Cr, Pb were 22.37, 52.52, 27.50, 0.48， 28.92 mg/kg， respectively, the average soil organic matter content along the Bortala River is 27 431 mg/kg. Soil pH value range from 6.5 to 7.5, with an average of 6.94. The correlation between soil properties and heavy metal contents in the study area is complex: Organic matter content is significantly correlated with contents of As, Cr, Cd and Pb. Organic matter is easy to form a complex with heavy metal ions, thereby reducing the heavy metal ion activity, resulting in increased heavy metal contents in soil. pH value show a negative correlation with the contents of As, Cd, Pb. With the increase of pH value, the contents of available As，Cd and content of available Pb in soil significantly reduced. By analyzing the correlation between soil organic matter, pH and heavy metals, it was found that soil organic matter and pH are the important factors affecting soil heavy metal contents.
