- 摘要:
- 对大宝山矿区6个功能区进行土壤基本性质分析和重金属含量测定,并分析其相关性.结果显示,土壤Cu,Zn,Pb,Cr含量以露采区最高,土壤Mn和Cd含量以尾矿库最高,大部分区域土壤重金属含量高于国家三级标准,各区域土壤重金属含量变异性较大,与区域功能和土壤来源有关.Cu,Pb,Zn含量之间具有较强相关性,且这三种重金属都与沙粒含量呈正相关,说明可能是由于人为活动释放到土壤中,有机质与Cu、pH、速效钾,粉粒与Mn,CEC与Cr、速效钾,pH与Cr呈正相关;全氮、pH与Cu,碱性氮与Mn,有机质与Cr,全磷、全氮、pH与Cr呈负相关.
- Abstract:
- The properties and heavy metal contents of soil samples taken from 6 function areas in Dabaoshan Mine were measured and the relationships between them were tested. The results showed that the contents of soil Cu, Zn, Pb, and Cr in Open-pit Mining Area were the highest; the contents of soil Mn and Cd in Caoduikeng Tailings Reservoir were the highest. The soil heavy metal contents of most area in Dabaoshan Mine were higher than grade Ⅲ of national environmental quality standard for soils. The variability of heavy metal contents of different areas was significant, which was related to the functions and origin of the soils. There was strong correlation between soil Cu, Pb and Zn content, and they were also correlated to sand particles positively, showing that the high contents of soil Cu, Pb and Zn maybe were caused by human disturbance. There were positive correlations between contents of soil organic matter and Cu, between pH, available potassium, silt particles and Mn and between CEC, available potassium and Cr. There were negative correlations between contents of total nitrogen, pH and Cu, between available nitrogen and Mn, between organic and Cd and between total phosphorus, total nitrogen, pH and Cr.
