摘要：

结合GPS采用网格法，对山东省聊城市耕地进行了136个样点11种重金属元素的测定。对各样点进行了重金属元素的富集指数计算，并利用GIS中的空间插值法将重金属元素富集程度进行空间分布研究。结果表明：聊城市土壤重金属元素富集程度从大到小依次为：Cu＞Hg＞V＞Zn＞Ni＞Cr＞Co＞As＞Mn＞Pb＞Cd。As、Co、Hg、Cu、Ni、Mn的最大富集值及Cd、Zn、V的最小富集值都出现在东阿县。不同重金属元素在各县市的富集程度存在着一定的差异。

Abstract:

The arable land in Liaocheng was distributed as 136 points to be monitored. 11 kinds of heavy metals had been monitored. The enrichment of all heavy metals had been calculated. The enrichment index showed that the pollution degree of 11 kinds of soil heavy metals were different. Their order was: Cu>Hg>V >Zn>Ni>Cr>Co>As>Mn>Pb >Cd. The heavy metals in 8 different regions had been counted, which showed that the largest enrichment index of As、Co、Hg、Cu、Ni、Mn were in Dong’e town. At the same time, the smallest enrichment index of Cd、Zn、V were in Don’t’e town too. There’s difference during different regions in Liaochent city.
