摘 要：
利用X-Ray荧光光谱仪测量土壤重金属含量,分析土壤重金属元素之间以及与土壤性质之间的相关关系。结果表明:研究区土壤重金属含量变化不大;Pb和Zn由表层到深层含量逐渐减少,具有一定表层富集效应;其他重金属变化规律不明显。相关性分析显示:As与Pb呈较强的负相关;As与Zn相关性较好;Cu与Ni、Cu与Zn呈显著的正相关;Ni与Zn之间的相关性较好。Pb含量与表层土壤有机质有较强的相关关系,As和Ni与较小粒径的含量成正相关关系,与细沙粒、中沙粒和粗沙粒的含量成负相关关系,而金属Cr、Pb的含量正好与之相反。

摘 要：
By X- Ray fluorescence spe ctrometer to measure soil heavy metal content, the correlations among soil heavy metal elements and among soil properties were analyzed. Results showed that soil heavy metal content in the study area changed little. The contents of Pb and Zn gradually reduced from the surface to the deep soil, which showed a certain surface concentration effect. The variation of other heavy metal content was not obvious. Correlation analysis showed that As had a strong negative correlation with Pb, but had a good positive correlation with Zn. Cu significantly positively correlated with Ni and Zn, and the correlation between Ni and Zn was strong, too. The correlation between Pb and the surface soil organic matter was strong. The correlations were positive between As and Ni and the content of small diameter, and As was negatively correlated with the content of fine sand, medium sand and coarse sand grains. Metal Cr and Pb, had the reverse correlation analysis to As.
