摘要

  • 摘要: 对云浮硫铁矿矿区及其周边土壤中Cu、Zn、Pb、Cd、Cr和Ni等元素含量进行了测定分析,利用地统计学方法研究了6种重金属的空间结构与分布特征。结果表明，6种重金属元素平均含量都超出当地土壤元素背景值；结构性因素对Cd、Cu、Zn的空间变异起着较显著的主导作用，而随机性因素对其空间变异的影响是较弱以及不显著的；Pb和Cr表现为具有中等程度的空间相关性，随机效应与结构效应相近；土壤中Cd、Cr、Cu与矿石加工企业以及矿渣的堆放密切相关，Zn的污染主要来源于农业施肥，Ni的含量除了受企业的影响外，农业施肥对重金属污染的影响也是不可忽略的。Pb含量的增加主要是由于矿石的开采造成。
    Abstract: The contents of six kinds of heavy metals (Cu、Zn、Pb、Cd、Cr、Ni) in soils of YunFu pyrite mining area were determined and analyzed. The spatial distribution characteristics of all the six kinds of heavy metal elements were analyzed based on geostatistics methods. The results showed that all the average contents of the six heavy metals had exceeded the local soil background values. By the results of semivariance analysis, structural factors played a leading role in the spatial variability on Cd, Cu and Zn, and the random factors played a much weaker role on Cd, Cu and Zn. Both of Pb and Cr showed a moderate degree of spatial correlation and their random factors were similar with the structural factors. The spatial distribution revealed that the contents of Cd,Cr and Cu in soil were closely related with the mineral processing enterprises and slag stacking, Zn pollutants were mainly from agricultural fertilizers. By our results, in addition to the influence by the mineral enterprises, the effects on the contents of Ni by agricultural fertilization could not be ignored. The increasing of Pb was mainly due to the extracting ore.
